← Life Sciences & MedicineIf a small group of finches colonizes a remote, previously uninhabited island, which evolutionary outcome becomes more pronounced?
A)Consistent natural selection pressures
B)Increased gene flow from mainland
C)Random genetic drift in population✓
D)Enhanced mutation rate adaptation
💡 Explanation
The effect of genetic drift becomes more pronounced in small, isolated populations because random events have a larger impact on allele frequencies. Therefore, the allele frequencies in the colonizing finch population will fluctuate randomly, rather than being driven by natural selection or gene flow.
