Why were reptiles able to evolve from amphibians?

Answer 1

All organisms are able to evolve through natural selection and genetic drift. All organisms experience a change over time.

A group of amphibians spent less time in the water, evolved dry skin and hard-shelled eggs and became the first reptiles.

Answer 2

Reptiles are more suited to dry conditions. Amphibians prefer moist habitats - as they absorb oxygen through their skin.
Amphibians lose their body moisture easily on land and they breathe through their skin, meaning the amphibians will suffocate eventually and are limited to areas around pools of water.

Answer 3

Being warm-blooded a mammal's metabolism is better suited to an active lifestyle as it generates heat more efficiently to power its own chemical processes. A reptile would have to spend some time basking in the sun in order to do that, exposing themselves to danger and wasting time warming up while they could be looking for food or looking for a mate.

Both groups' reproductive strategies are adapted to land but mammals' young develop inside the womb and most look after their young while a reptile lays hard-shelled eggs and most don't look after their offspring.

Answer 4

reptiles have scales (hard skin) to protect them and anphibians don't

Answer 5

Reptiles do not need to return to water for any stage of life

Answer 6

Amphibians are older and reptiles are more developed.
