Closely related species exhibit different traits due to accumulated genetic differences over time.
Two closely related species such as chimpanzees and gorillas have different traits because they have accumulated genetic differences over time through mutations that have led to distinct traits and characteristics.
This genetic divergence can be measured by comparing the differences in DNA sequences between species, with fewer genetic differences indicating a more recent common ancestor.
The anatomical differences observed between closely related species like chimpanzees and humans highlight how minor genetic changes can result in significant morphological variations despite high genetic similarity.
