Did mammals and birds evolve from fish?
Amphibians, reptiles, mammals, and birds evolved after fish. The first amphibians evolved from a lobe-finned fish ancestor about 365 million years ago. Mammals and birds both evolved from reptile-like ancestors. The first mammals appeared about 200 million years ago and the earliest birds about 150 million years ago.
Which describes a difference between birds and mammals?
The birds have feathers whereas mammals have only fur or hair. Birds have wings although mammals have paws, hands, and hooves. There is also a difference in the feeding of the young. Mammals feed their young milk produced by the mammary glands.

How did mammals evolve from fish?
Amphibians, reptiles, mammals, and birds evolved after fish. The first amphibians evolved from a lobe-finned fish ancestor about 365 million years ago. They were the first vertebrates to live on land, but they had to return to water to reproduce. Mammals and birds both evolved from reptile-like ancestors.
What is the common ancestor of mammals and turtles?
The first amniotes apparently arose in the middle Carboniferous from the ancestral reptiliomorphs. Within a few million years, two important amniote lineages became distinct: mammals’ synapsid ancestors and the sauropsids, from which lizards, snakes, turtles/tortoises, crocodilians, dinosaurs, and birds are descended.
Are turtles mammals?
