Question

the similarity of the bone structrues in the forelimbs of mammals is an example of:
a homologous structures
b analogous structures
c convergent evolution
d divergent evolution

Answer 1

The similarity of the bone structures in the forelimbs of mammals is an example of:

**a) homologous structures.**

Homologous structures are anatomical features in different species that share a common ancestor, even if they have different functions. In this case, the forelimbs of mammals (such as humans, bats, and whales) have similar bone structures despite being adapted for different purposes (manipulation, flying, swimming), illustrating their common evolutionary heritage.
