over several thousand years the birds descendants evolve webbed feet and begin to feed on fish. is this an example of gradualism or punctuated equilibrium?
Dinosaurs emerged first. Some dinosaurs were birds, but they didn't come until later.
The first true birds likely evolved in the Late Jurassic and Early Cretaceous periods.
The five classes of vertebrates (fish, amphibians, reptiles, birds, mammals) evolved in the following order: fish appeared first, followed by amphibians, then reptiles, birds, and finally mammals. Each class adapted and diversified to exploit different environments and ecological niches over millions of years.
fish, dinosaurs, birds
The correct order in which vertebrates evolved is fish, amphibians, reptiles, birds, and then mammals. Fish were the first vertebrates to appear, followed by amphibians that adapted to life on land. Reptiles evolved next, leading to the development of birds and eventually mammals. Thus, the correct sequence is fish, amphibians, reptiles, birds, and mammals.
