Answer
The rapid evolution of insulin in guinea pigs and coypu could be due to several factors, including environmental pressures, genetic drift, or a high mutation rate in the insulin gene.
Solution
a
Genetic Drift: Random changes in allele frequencies could lead to a faster evolution of certain genes, including insulin
b
Environmental Pressures: Unique ecological niches or dietary habits might exert selective pressures that accelerate the evolution of insulin
c
Mutation Rate: An increased mutation rate in the insulin gene could result in a faster evolution compared to other species
Key Concept
Evolutionary Rate Variation
Explanation
The rate of evolution for a particular gene can vary between species due to factors like genetic drift, environmental pressures, and mutation rates.
