The arm bones of a whale, bat, bird, and human are all examples of _______________ structures.

The limbs of humans, cats, whales, and bats are examples of homologous structures. All of these structures—arm, leg, flipper, and wing—are supported by the same type of bone structure. Divergent evolution leads to homologies.

What are Homologous structures ?

Homologous structures are those that share a fundamental structure but serve distinct purposes.

Divergent evolution is an evolutionary trend in which species with similar ancestry gradually diverge over the course of an evolutionary time period as a result of differential selection pressure.

Predation, food supplies, and competition for mates are a few examples of these stressors.
