The two animals that exhibit the most linear relationship based on the characteristics described are birds and reptiles. Both groups have scales (in the case of reptiles), feathers (a specialized form of scales in birds), and they share a more recent common ancestor than the other groups listed. Additionally, birds are often classified within the group of reptiles in terms of evolutionary biology, making their relationship more direct and linear.
Fish, amphibians, reptiles, birds, and mammals have similar embryos. They all start with gill slits. Fish and some amphibians grow to have gills. Some amphibians, reptiles, birds, and mammals develop lungs to breathe air. They all start with tails. Fish, some amphibians, reptiles, and birds grow tails. Humans do not keep their tails. Fish and reptiles develop scales. Amphibians, birds, and humans have skin. Birds have feathers, and humans have hair.
