Answer 1

Answer is: This muscle layer found inserted under the dermis, called panniculus carnosus musculature, is first observed in reptiles and allows for independent movement of the skin.

Explanation:

Panniculus adiposus is a adipose layer and contains loose connective tissue that connects the skin and panniculus carnosus muscle.

The panniculus carnosus is first observed in reptiles. It allows movement of the skin which is independent to the movement of deeper muscle masses.
