Answer 1

The correct answers are:

1. Lizards;

The animals started to develop traits that would protect them from the natural elements after the lizards. Because of the changes in climate, as well as changes in the functioning of the organism and developing from cold blooded to warm blooded, the animals started to develop feathers and hairs (later becoming a full body fur).

2. Jelly fish;

The Jelly fish is an organism that is very primitive. It has remained largely unchanged throughout the geological time and it seems like it hadn't any real reason to evolve further. It is also one of the oldest species that are still in existence, but also a species that is older even than the hagfish.
