What group of animals is thought to have moved onto land to become the first amphibians? |
Step by step
Solved in 2 steps
- Why do you think the ancestors of the extant amphibians became successful in adapting from the life on water to life on land?Professor Andrew, a paleontologist discovers a transitional fossil between a stem amniote and mammal. In 150 words express on what group of animals this might have belonged to and on their major antomical features !Although most salamanders have four legs, a few species that live in shallow water lack hind limbs and have extremely tiny forelimbs (see photograph).Develop a hypothesis to explain how limbless salamanders came about according to Darwin’s mechanism of evolution by natural selection. How could you test your hypothesis?
