What are the two main classes of fish?

Last century there were two main classes only: plants and animals, so fish are by themselves, neither reptile nor amphibian, but alongside other groups. Classification developed because it became too difficult in the early 20th century to group living things into one or the other of only two groups.

Why do all embryos look the same?

Embryos Look closely at any mammal, bird, or amphibian embryo—they all look the same. That’s because they all inherited genes from a common, fishy ancestor.
