Answer: Life on Earth began in the water. So when the first animals moved onto land, they had to trade their fins for limbs, and their gills for lungs, the better to adapt to their new terrestrial environment. ... In air, eyes can see much farther than they can under water. Tetrapods evolved from a group of organisms that, if they were alive today, we would call fish. They were aquatic and had scales and fleshy fins. ... Between 390 and 360 million years ago, the descendents of these organisms began to live in shallower waters, and eventually moved to land.

Which nervous system regulates involuntary activities that you probably don’t even realize are happening?
Feliz [49]
The correct answer should be
<span>D. Autonomic nervous system

It is called autonomic because it works on its own and it regulates organs functioning which is a thing that happens involuntarily. It regulates heart beats for example and it's not something that you do voluntarily since the heart beats regardless of you. It also controls things like vomiting or sneezing that you can't choose not to do when it starts happening.</span>
