Answer 1

"Dave", the feathered lizard fossil is thought of as a(n) homologous species, or an organism that may represent a common ancestor shared by different but related lineages of organisms.

What is homologous evolution?

Homologous evolution is similarity of the structure, physiology, or development of different species of organisms based upon their descent from a common evolutionary ancestor.

Homologous structures include the human arm, a bird or bat's wing, a dog's leg, a dolphin or whale's flipper, and the wing of a bird or a bat. They are distinct and serve different purposes, although they are comparable and have similar characteristics. They are regarded as homologous structures because their underlying anatomies are comparable.
