Natural Selection and Heritable Variation
A scientist suggests that darker fur is becoming more common in a polar bear population because it enhances solar radiation absorption. The scientist’s explanation, however, does not account for the heritability of fur color. This reasoning is flawed because it overlooks the principle that:
A
Incorrectly attributed fur color changes to climate change alone
B
Neglected the potential for gene flow to affect fur color distribution
C
Failed to consider the genetic determinants of fur color
D
Overlooked the role of natural selection in fur color variation
