Answer
Variation within a species is crucial for evolution by natural selection.
Solution
a
Genetic variation: Genetic differences among individuals in a population may result in different traits (phenotypes)
b
Differential survival and reproduction: Individuals with traits that are advantageous in a particular environment are more likely to survive and reproduce
c
Inheritance of advantageous traits: The advantageous traits are passed on to the next generation, leading to a change in the population over time
Key Concept
Genetic variation is the foundation of natural selection.
Explanation
Without variation, there would be no differential survival and reproduction, and thus no evolution by natural selection. Over time, the accumulation of these advantageous traits can lead to the emergence of new species.
