birds like to lay fossils. Salamanders have tails btw.

Hope this helped!

The fossil bird and salamander both have different tail structure because they both inherited tails from a shared ancestor population initially, but this population eventually separated into different environments.

  • In order to adapt into their immediate environment they both evolve their tail structure to carry out different functions.

 

How does evolution occur?

  • It is the change in the phenotypic characters  of a species over several generation resulting from natural selection and genetic drift.

  • The  the tail of salamander  was evolved to store fat and proteins, assistance in the movement, hence it has long tail with many bones for ease of movement.

  • Whereas birds short and light weight tail for the ease of flying and normal functioning.

Hence, different body structure evolved from the same ancestors for the adaptation in different species.
