Question

On an isolated island you discover a vertebrate animal that has never been described before. It has feathers, a feathered, bird-like tail, lays hard-shelled eggs and can fly, but it has teeth instead of a beak. Provide an explanation for the evolution of this animal and possible relationship with other clades of vertebrates that accounts for this unusual combination of features.

Answer 1

In the evolution, the variation in the morphology and into the gene by the surrounding it happens by millions of years due to this variation several natural factors like genetic drift due to catastrophic activity and due to the reproductive isolation barriers or due to the process of natural selection many animals plants shows mixed characters during the course of evolution.

by showing the character on the following animals it can be concluded that the species may come from the animals or vertebrate but the It has feathers, a feathered, bird-like tail, lays hard-shelled eggs and can fly, and has teeth instead of a beak that shows that during the evolution by the genetic drift or some kind of isolation the two group of the one species or the two group are divided by the separation of the continent and the organisms separate out due to this separation they are reproductively isolated and the environment it might be helpful or harsh to the isolated groups for surviving the modification in the characters like the feathers, a feathered, bird-like tail, lays hard-shelled eggs and can fly, but it has teeth instead of a beak can be acquired or can be modified by the surrounding environment. by acting on the natural selection the organisms have the permanent changes in its gene and the morphology and due to variation, the morphological changes can occur.

it can be lead to the relates with the ave's which are evolved from the animals in the evolution by millions of years ago by adapting an avian character like feathers, a feathered, bird-like tail, lays hard-shelled eggs and can fly, and has teeth instead of a beak. the origin and the diversification of the birds on the phylogeny tree and the character showing in our case is close to the vertebrates in aniamals
