Early amphibians
Early amphibians evolved from fish who used fins like legs...
375 million years ago, long before the dinosaurs, the ancestors of amphibians developed from fish that used their fins like legs to walk along the sea bed.
First creatures to walk on four legs on land were amphibians...
These ancient amphibians were the first animals to walk on four legs on land. They adapted to many different environments, and evolved into the predecessors of most land-dwelling creatures, including the dinosaurs.
Our hands and feet evolved from same bone structures as amphibians...
As they share a common ancestor, today's amphibians are surprisingly similar to other types of land animals.
Aquatic and terrestrial lifestyle...
The word 'amphibians' means 'two lives'. As many live mainly on land but need water in which to breed and raise tadpoles, they really do lead a double life.
