What BIOL1004 covers
BIOL1004 (Biology 1B: Evolution and Diversity of Organisms) moves from six evolution topics through protists and fungi, plant and animal biology, then population ecology.
The map follows the material actually available for Semester 1, 2026: full pages where the course publishes them, practical and quiz evidence where topic pages are absent, and explicit signposts back to MyLearning for missing animal physiology, Ecology Part 2 and the glossary-only plant topics.
Natural Selection: Darwin's Observations and Inferences
Defining life; hierarchy of biological organisation; emergent properties; the three domains; descent with modification; Darwin and Wallace; two observations, three inferencesLiving systems grow, metabolise, respond to stimuli, reproduce and show adaptation; the course uses viruses to test why possessing only some features is not enough.
- not enough.
- Biological organisation runs from molecules through organelles, cells, tissues, organs, organisms, populations, communities, ecosystems and the biosphere.
- Emergent properties appear when parts interact at a higher level, so the behaviour of a whole cannot be read from an isolated component alone.
- Bacteria, Archaea and Eukarya are the three domains; the classification establishes deep evolutionary branching rather than a ladder of progress.
- Descent with modification means lineages inherit features while accumulating changes, producing a branching history rather than a monkey-to-human chain.
- Darwin and Wallace independently developed natural selection as a mechanism that can explain adaptation without organisms choosing to change.
Evidence for Evolution and Models of Selection
Fossil, anatomical, genetic and experimental evidence; body vs trace fossils; rock types and unconformities; whale case study; homology; haemoglobin; corn-oil and soapberry-bug experiments; directional, stabilising, disruptive selectionThe course organises evidence into fossil, anatomical, genetic and experimental lines; strong answers state what each line independently contributes.
- The course organises evidence into fossil, anatomical, genetic and experimental lines; strong answers state what each line independently contributes.
- Body fossils preserve part of an organism, whereas trace fossils preserve activity such as tracks or burrows; they answer different biological questions.
- Sedimentary rock can preserve remains, while heat and transformation make igneous and metamorphic contexts much less suitable for fossil preservation.
- Superposition orders undisturbed strata relatively, while unconformities expose missing time and explain why a fossil sequence can be incomplete.
- The course gives 3.7 billion years for the earliest fossils on one page and about 3.5 billion years for the oldest fossils on another; the guide presents the conflict rather than choosing.
- The Pilbara cross-section caption has its own 3.35-3.46 billion-year range and must not be fused with the separate 3.7-billion-year statement.
Variation, Species Concepts and Phylogenetic Trees
Populations and gene pools; five sources of genetic variation; four species concepts; binomial nomenclature and the classification hierarchy; analogous vs homologous traits; symplesiomorphy, synapomorphy, autapomorphy; building a cladogramA population is a local group of the same species whose members can interbreed; its gene pool contains the alleles carried by that group.
- a local group of the same species whose members can interbreed; its gene pool contains the alleles carried by that group.
- a proportion in a gene pool, and population evolution is tracked as a change in such frequencies across generations.
- The mound-spring spider case shows why population boundaries matter: isolated springs can hold distinct local gene pools.
- The course lists recombination, mutation, gene flow, Mendelian inheritance and orthologous or paralogous gene histories as sources or patterns of variation.
- Independent assortment and crossing over rearrange existing alleles, whereas mutation can introduce a new allele.
- Gene flow moves alleles between populations and can counter divergence when migration connects local gene pools.
Fitness, Adaptation and Speciation
Biological vs everyday fitness; relative fitness; why survival of the fittest is incomplete; adaptation as inherited and dynamic; allopatric and sympatric speciation; drift, founder effect, bottlenecks; gradual evolution of complex traitsBiological fitness combines survival and reproduction; survival without offspring does not contribute genes to the next generation.
- Biological fitness combines survival and reproduction; survival without offspring does not contribute genes to the next generation.
- The course lists age at first reproduction, current age, survival at each age and female offspring produced at each age as fitness components.
- Relative fitness compares contributions within a particular population and environment rather than assigning an absolute score to a species.
- incomplete because it omits reproduction and can tempt circular reasoning.
- Natural selection requires genetic variation; without heritable differences, unequal survival cannot accumulate as evolutionary change.
- inherited, improves survival and reproduction in a specific environment and can lose its advantage if conditions change.
Sexual Reproduction and Sexual Selection
The two-fold cost of sex and recombination load; genetic variation, DNA repair, Muller's ratchet and the Red Queen; the nematode co-evolution experiment; Bateman's principle; male competition and female choiceSex is widespread among multicellular eukaryotes and present in some single-celled organisms, so the question is why it persists despite costs.
- widespread among multicellular eukaryotes and present in some single-celled organisms, so the question is why it persists despite costs.
- The two-fold cost compares halved reproductive output with asexual exponential growth when only one sex directly produces offspring.
- Recombination load occurs when recombination breaks apart a high-fitness allele combination, illustrated with A and a frequencies and AA as the highest-fitness genotype.
- Sex can increase genetic variation by creating new combinations of alleles, giving selection more combinations to act upon.
- DNA repair can use non-homologous end joining or homology-directed repair, with homologous information providing a template.
- lost.
History of Life and Adaptive Radiation
Geological time; oldest evidence of life; the major-events table; features of Archaea, Bacteria and Eukarya; three causes of adaptive radiation; Galapagos finches; Cambrian explosion; Permian extinction; homeobox genesEarth is placed at roughly 4.5-4.6 billion years, with the Precambrian covering most of that history before the Phanerozoic.
- placed at roughly 4.5-4.6 billion years, with the Precambrian covering most of that history before the Phanerozoic.
- The page presents about 4.2 billion years for a genetically inferred last universal common ancestor, which is an inference rather than a fossil date.
- Oldest-fossil ages conflict across course pages at 3.7 and about 3.5 billion years; both readings are retained with attribution.
- The same history page gives first multicellular organisms as 570 million years in its table and about 770 million years in prose.
- First eukaryotes are 1.6 billion years on the history page and around 1.8 billion years on the protist page.
- Archaea and Bacteria are prokaryotic domains, while Eukarya includes cells with a nucleus and membrane-bound organelles.
Protists: Diversity, Nutrition and Life Cycles
Why protists are paraphyletic; shared eukaryotic features; heterotrophy, autotrophy, mixotrophy; primary and secondary endosymbiosis; diplontic, haplontic and sporic life cycles; algae, Plasmodium, slime moulds, EuglenaProtists are eukaryotes that are not animals, plants or fungi, so the label is convenient but does not name one clade. All protists have a nucleus enclosed by a double membrane, membrane-bound organelles and a developed cytoskeleton.
- convenient but does not name one clade.
- All protists have a nucleus enclosed by a double membrane, membrane-bound organelles and a developed cytoskeleton.
- Most are unicellular, while some are multicellular and some possess cell walls; those qualifiers must not be converted into universal claims.
- The course contrasts roughly 100,000 described species with estimates ranging from several hundred thousand to more than 1.5 million.
- Heterotrophs obtain organic material from other organisms; Amoeba and Paramecium are the featured examples.
- Autotrophs such as Chlamydomonas and diatoms make organic molecules using light, while mixotrophs such as Euglena can combine modes.
Fungi: Structure, Reproduction and Symbioses
Chitin walls, glycogen storage, absorptive heterotrophy; hyphae, septa and mycelium; moulds, yeasts and dimorphic fungi; asexual and sexual spores; dikaryons; lichens and mycorrhizae; crop and human pathogensFungi form a monophyletic kingdom more closely related to animals than to plants. Their core features are heterotrophy, absorption of small molecules, chitin cell walls and glycogen storage.
- Fungi form a monophyletic kingdom more closely related to animals than to plants.
- Their core features are heterotrophy, absorption of small molecules, chitin cell walls and glycogen storage.
- Hyphae are chains of cells that grow at their tips and collectively form a mycelium.
- Septa can contain large pores, while coenocytic hyphae lack cross-walls and contain continuous cytoplasm.
- a reproductive structure produced by a much larger mycelium, captured by the apple-to-apple-tree comparison.
- Mould, yeast and dimorphic growth forms describe morphology and are not themselves evolutionary groups.
Plant Life Cycles and the Move onto Land
Alternation of generations; gametophyte and sporophyte dominance; homospory and heterospory; Bryophyta, Pterophyta, Coniferophyta, Anthophyta compared; controlling water loss; key features of true land plantsPlants are presented as descendants of a green algal ancestor, but dates for terrestrialisation conflict at about 420, 470, 475 and 500 million years. Alternation of generations contains a diploid sporophyte and a haploid gametophyte, both multicellular.
- Plants are presented as descendants of a green algal ancestor, but dates for terrestrialisation conflict at about 420, 470, 475 and 500 million years.
- Alternation of generations contains a diploid sporophyte and a haploid gametophyte, both multicellular.
- The sporophyte produces haploid spores by meiosis; the gametophyte produces haploid gametes by mitosis.
- Bryophytes are gametophyte-dominant, whereas vascular plants shift dominance toward the sporophyte.
- A pollen grain is a microscopic male gametophyte rather than a gamete.
- Homosporous plants make one spore type, while heterosporous plants make microspores and megaspores.
Angiosperm Reproduction: Flowers, Fertilisation, Fruits
The three Fs; stamen and carpel; embryo sac and pollen grain; pollination and pollen tubes; double fertilisation and 3n endosperm; seed and fruit development; simple, aggregate, multiple and accessory fruits; vegetative reproduction and apomixisThe chapter's three Fs are flowers, double fertilisation and fruits, which organise the angiosperm life cycle. A stamen consists of anther and filament and is the male floral structure; anthers contain microsporangia that make pollen.
- The chapter's three Fs are flowers, double fertilisation and fruits, which organise the angiosperm life cycle.
- the male floral structure; anthers contain microsporangia that make pollen.
- the female floral structure.
- Petals and sepals are sterile: petals can attract pollinators and sepals protect the developing flower.
- Within an ovule, a megasporangium produces a megaspore that develops into the embryo sac or female gametophyte.
- Within an anther, microsporangia produce microspores that develop into pollen grains.
Plant Structure, Growth and Transport
Dermal, ground and vascular tissue; apical and lateral meristems; primary and secondary growth; monocot vs eudicot anatomy; stomata and mesophyll; wood, bark and periderm; apoplast, symplast, Casparian strip; cohesion-tension; phloem source to sinkDermal, ground and vascular tissues provide the major structural framework used in the practical and quiz material. Meristems are unspecialised dividing tissues; apical meristems drive primary growth and lateral meristems drive secondary growth.
- Dermal, ground and vascular tissues provide the major structural framework used in the practical and quiz material.
- Meristems are unspecialised dividing tissues; apical meristems drive primary growth and lateral meristems drive secondary growth.
- Root primary growth passes through zones of cell division, elongation and differentiation or maturation.
- the innermost cortex layer, while the pericycle gives rise to lateral roots.
- Eudicot roots show star-shaped central xylem with phloem between the arms; monocot roots have a parenchyma core surrounded by alternating vascular tissues.
- removed or shaded.
Animal Body Plans, Digestion and Gas Exchange
Anatomical direction terms; diploblastic and triploblastic; acoelomate, pseudocoelomate, coelomate; insect gut regions and the tracheal system; amphibian vs mammalian respiratory and digestive anatomyDistal and proximal, dorsal and ventral, anterior and posterior, superior and inferior, rostral and caudal, lateral and medial must be applied from the named reference point.
- Distal and proximal, dorsal and ventral, anterior and posterior, superior and inferior, rostral and caudal, lateral and medial must be applied from the named reference point.
- Transverse and longitudinal sections describe the plane of a cut, not the animal's external direction.
- Dissection separates tissues where possible, uses scissors rather than scalpels in first-year biology and positions invertebrates dorsal-up but vertebrates ventral-up.
- Cockroach spiracles open to a branching tracheal system that delivers oxygen directly to body cells.
- The insect gut sequence includes mouth, oesophagus, crop, proventriculus or gizzard, foregut, gastric caecae, midgut, malpighian tubules, hindgut, rectum and anus.
- Triploblastic animals develop ectoderm, mesoderm and endoderm, with mesoderm separating the outer and inner layers.
Population Ecology and Growth Models
Populations and metapopulations; births, deaths, immigration, emigration; density dependence and carrying capacity; r- and K-strategists; sex structure, mortality, life tables, survivorship curves; exponential and logistic growthA population contains members of the same species in a defined area that share resources, experience similar conditions and can interbreed.
- A population contains members of the same species in a defined area that share resources, experience similar conditions and can interbreed.
- A useful boundary must be explicit and biologically sensible; the Adelaide 1.3-million example illustrates how scale changes the population being counted.
- A metapopulation is a set of spatially distinct populations connected by some immigration.
- Population dynamics depend on births, deaths, immigration and emigration, while density, distribution, age structure and sex ratio describe state.
- Density-dependent effects strengthen with population density and relate to carrying capacity K; density-independent events act externally.
- r-selected profiles grow rapidly, reproduce early, produce many small offspring with little care and can overshoot K before crashing.
Lab Skills: Microscopy, Drawing and Data
Lab safety and PPE; dissecting vs compound microscope set-up; micrographs, scale bars and figure legends; scientific drawing standards; data standardisation and plotting; how worksheets are marked and feedback loopsRequired laboratory conduct includes closed shoes, a long-sleeved lab coat kept within biology labs, tied hair and safety glasses when specified.
- Required laboratory conduct includes closed shoes, a long-sleeved lab coat kept within biology labs, tied hair and safety glasses when specified.
- Food and drink are excluded, biological material remains in the laboratory and accidents or spills are reported immediately.
- Students wait outside, work in pairs, share the lab computer and store bags in the under-bench cupboard.
- Pack-up returns equipment, logs out, stores the keyboard, cleans with ethanol and ends with hand washing.
- Standard bins take uncontaminated waste but not gloves or tips; biohazard bins take tips, gloves, tubes and petri dishes even when unused.
- Glass containers take broken glass, Pasteur pipettes, slides and coverslips; sharps containers take needles, razor blades and scalpels.
Its teaching sequence begins with the origin of biological diversity, evolutionary evidence, population variation, species concepts and phylogenetic trees, fitness and speciation, sexual reproduction and sexual selection, and the history of life.
It then moves through protist and fungal diversity, plant life cycles, angiosperm reproduction, plant growth and transport, practical animal body plans, population ecology and laboratory practice.
The source coverage is uneven and this guide keeps that boundary visible: Animal Biology has practical anatomy but no topic pages; Ecology Part 2 is absent; Plant Topics 1 and 3 rely on practical and quiz evidence; Plant Topics 6 and 7 are represented only in the glossary. Missing mechanisms are directed back to MyLearning rather than filled from a generic biology syllabus.
Assessment is a 30% Learning Engagement Portfolio in three parts, five preliminary practical quizzes worth 5% total, five paired practical worksheets worth 25% total and a 40% final exam. The final exam is closed book, three hours and 120 marks.
Sixty marks are 60 multiple-choice questions drawn from the ten Week Review Quizzes at six questions per quiz; the other 60 marks are short answer at approximately six marks for each teaching week. The course states that the exam is not a hurdle. Its date is not published in the materials available here, so students are directed to the Student Portal timetable.
The Week Review Quizzes carry no direct marks and are optional, but a result of at least 65% can be used as an additional portfolio artifact. Preliminary practical quizzes are graded, allow unlimited attempts before the close, retain the highest result and close at the start of the enrolled practical with no late submission.
Worksheets are completed in pairs, submitted before leaving and cannot be submitted by a student who did not attend; feedback is read and carried into the next worksheet. Campbell Biology 12e is recommended but explicitly not compulsory, and the course also points to free alternatives.
Worked example · free
Link an optional quiz to both assessment pathways
- unweightedFirst identify the exam pathway. All multiple-choice questions in the final exam are drawn from the ten Week Review Quizzes, with six questions selected from each quiz. Completing the quiz is therefore direct retrieval practice for half of the 120-mark exam.
- unweightedThen identify the portfolio pathway. A screenshot showing at least 65% can count as an additional Learning Engagement Portfolio artifact for that week. The quiz itself carries no direct mark, but its result can support the 30% portfolio.
- unweightedKeep the components separate. Do not say the Week Review Quiz is graded, and do not confuse it with the graded preliminary practical quiz that closes at the start of the enrolled practical.

BIOL1004 FAQ
Is the BIOL1004 final exam a hurdle?
No. The course explicitly states that the final exam is not a hurdle: a result below 50% on the exam can still be compatible with passing when performance across practicals, portfolios and the exam produces an overall passing result. All four configuration rows keep is_hurdle false; other component hurdle status is not stated and should be confirmed on MyLearning.
How is the Biology 1B exam structured?
It is a closed-book, in-person written exam lasting three hours for 120 marks. Sixty marks come from 60 multiple-choice questions and 60 marks come from short-answer questions, with approximately six short-answer marks for each of ten teaching weeks.
Where do the exam multiple-choice questions come from?
All of them are drawn from the ten Week Review Quizzes, with six questions selected from each quiz. Some non-MCQ quiz formats can be converted into multiple-choice form.
Do the Week Review Quizzes count for marks?
Not directly; they are described as optional and not for marks. However, a screenshot of at least 65% can count as an additional portfolio artifact for that week, and the quizzes supply the entire exam MCQ pool.
What happens if I miss a practical?
The published practical instructions say a student who is not in the practical cannot submit the worksheet. Follow the absence process and confirm the current procedure on MyLearning.
Can I retake a prelim quiz?
Yes, before the deadline. The quiz has no time limit, permits unlimited attempts before it closes and keeps the highest mark. It closes at the start of the enrolled practical class and cannot be submitted late.
Do I have to buy Campbell Biology?
No. The course says purchasing Campbell Biology is not compulsory, though it may be advantageous, and it also lists free alternatives.
How much is the Learning Engagement Portfolio worth?
It is worth 30% and is submitted in Parts A, B and C. The split of the 30% across those parts is not published in the available materials, so confirm it on MyLearning.
Questions students ask in each BIOL1004 chapter
- What is the core reasoning skill in Natural Selection: Darwin's Observations and Inferences?
- The core skill is turning Darwin's observations into a causal explanation of natural selection. The fastest revision test is to apply the five-part logic to a fresh trait and identify which link would fail if the trait were not inherited. Chapter 01 · Natural Selection: Darwin's Observations and Inferences
- What is the core reasoning skill in Evidence for Evolution and Models of Selection?
- The core skill is matching each line of evidence to the evolutionary claim it can actually support. The highest-value synthesis is convergence: fossils, anatomy, sequences and experiments support common descent on different timescales. Chapter 02 · Evidence for Evolution and Models of Selection
- What is the core reasoning skill in Variation, Species Concepts and Phylogenetic Trees?
- The core skill is moving from variation in a gene pool to a defensible cladogram and species claim. A defensible answer states the grouping rule, identifies the outgroup and names the synapomorphy that supports each internal branch. Chapter 03 · Variation, Species Concepts and Phylogenetic Trees
- What is the core reasoning skill in Fitness, Adaptation and Speciation?
- The core skill is explaining how reproductive success, isolation and stochastic processes reshape populations. Strong answers name the mechanism, the population scale, the source of divergence and the evidence for reproductive isolation. Chapter 04 · Fitness, Adaptation and Speciation
- What is the core reasoning skill in Sexual Reproduction and Sexual Selection?
- The core skill is weighing the costs and benefits of sex using predictions and experimental evidence. A strong experiment answer identifies arms, controlled contrast, prediction, observed pattern and the conclusion actually supported. Chapter 05 · Sexual Reproduction and Sexual Selection
- What is the core reasoning skill in History of Life and Adaptive Radiation?
- The core skill is reading the history of life as an evidence-based timeline with explicit uncertainty. The synthesis move is to connect geological opportunity, extinction, developmental genes and ecological competition without treating any one as a universal cause. Chapter 06 · History of Life and Adaptive Radiation
- What is the core reasoning skill in Protists: Diversity, Nutrition and Life Cycles?
- The core skill is tracking nutrition, endosymbiosis and ploidy through a deliberately diverse assemblage. The recurring exam skill is to identify which cell division changes ploidy and which preserves it. Chapter 07 · Protists: Diversity, Nutrition and Life Cycles
- What is the core reasoning skill in Fungi: Structure, Reproduction and Symbioses?
- The core skill is linking fungal structure and reproduction to absorptive nutrition and symbiosis. A strong comparison separates body form, nuclear state, spore origin and nutritional relationship rather than treating all fungi as mushrooms. Chapter 08 · Fungi: Structure, Reproduction and Symbioses
- What is the core reasoning skill in Plant Life Cycles and the Move onto Land?
- The core skill is following alternation of generations while separating firmly sourced plant content from missing topic pages. The safest life-cycle answer labels ploidy at every arrow and names whether mitosis, meiosis or fertilisation occurs. Chapter 09 · Plant Life Cycles and the Move onto Land
- What is the core reasoning skill in Angiosperm Reproduction: Flowers, Fertilisation, Fruits?
- The core skill is following flower structures through double fertilisation to seeds and fruits. A complete answer keeps anther-to-stigma pollination, pollen-tube growth and the two fusion events in their correct order. Chapter 10 · Angiosperm Reproduction: Flowers, Fertilisation, Fruits
- What is the core reasoning skill in Plant Structure, Growth and Transport?
- The core skill is connecting plant tissues and meristems to directional transport through roots, shoots and leaves. Plant Topics 6 and 7 are represented only by glossary terms, so soil nutrition, hormones and defence are defined but not expanded beyond the available material. Chapter 11 · Plant Structure, Growth and Transport
- What is the core reasoning skill in Animal Body Plans, Digestion and Gas Exchange?
- The core skill is using the practical specimens to compare body cavities, digestive surfaces and respiratory anatomy without importing missing physiology topics. Chapter 12 is intentionally thin because practical anatomy is the grounded limit of the available animal teaching content. Chapter 12 · Animal Body Plans, Digestion and Gas Exchange
- What is the core reasoning skill in Population Ecology and Growth Models?
- The core skill is keeping the course's Theory and Maths sections connected through population change. Ecology Part 2 content is absent, so the chapter ends at population ecology rather than inventing community or ecosystem topics. Chapter 13 · Population Ecology and Growth Models
- What is the core reasoning skill in Lab Skills: Microscopy, Drawing and Data?
- The core skill is turning practical procedures, records and figures into reproducible evidence. Worksheets are completed in pairs, submitted before leaving, cannot be submitted without practical attendance and feed demonstrator comments into the next worksheet. Chapter 14 · Lab Skills: Microscopy, Drawing and Data
How to study for the exam
Build revision around the ten Week Review Quiz pools because they are the published source for every exam multiple-choice question. For short answer, practise complete causal chains: variation to selection, character matrix to cladogram, isolation to speciation, ploidy through a life cycle, flower to seed, root to shoot to air, source to sink, body plan to function, and births or deaths to population change.
Keep a conflict ledger for dates and labels rather than averaging them. Before each practical, use the unlimited prelim-quiz attempts to diagnose gaps; during the class, produce labelled figures and data records that another student could interpret; afterward, read the demonstrator's feedback with your partner and write one correction into the next worksheet.
Where this guide says material is absent or glossary-only, use the live MyLearning module as the source rather than extending the topic from general biology memory.
