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.

The two animals that exhibit the most linear relationship based on the information provided are amphibians and reptiles.
Both amphibians and reptiles share similarities in their embryonic development (gill slits, tails), and they both can have similar skin structures (moist skin for amphibians and scaly skin for reptiles). Moreover, both groups are part of the tetrapod lineage and have closer evolutionary ties, making their relationship more linear in comparison to others listed.
