Question

Which of the following provided structural evidence for the concept of a common ancestor

Answer 1

Physical characteristic was present in a common ancestor, species may have similar physical characteristics (homologous structures).

What are homologous structures?

A physical trait that distinguishes two or more species, such as a complicated bone structure or a body plan, may have been passed down from a common ancestor.

A common ancestor's evolutionary history causes physical characteristics to be homologous.

Sometimes, structures in an organism are similar to crucial structures in other animals, but they no longer serve the primary ancestral role. Vestigial structures are these structures, which are frequently scaled down.

Therefore, Physical characteristic was present in a common ancestor, species may have similar physical characteristics (homologous structures).
