Question

7) Whale flippers, bat wings, and cat legs are considered to be “homologous structures’” because they have the same skeletal parts, despite the fact that they have different functions. Remember that the prefix "homo" means the same. What do these “homologous structures” tell us about the evolution of the whale, bat and cat? *

Answer 1

In simple words, Homologous structures refers to the organs or atlas device of invertebrates which recommend their connection to a common origin by virtue of their similarity. Such systems do not appear precisely the same, or have the same features.

Both bats as well as humans were primates, so both possess a shared ancestor. Both the wings of a bat as well as the hand of a person have a common internal body shape, although they appear somewhat different from the outside.

A further indication of whales possessing a sequence homology form is their ear canal bones. A whale's inner ear bones are nearly identical to terrestrial mammals however the one distinction is that they've been fused around each other.
