Years ago, there was a popular theory that humans were descendants of aquatic apes who were accustomed to living and hunting in shallow lakes and along shorelines, instead of on the savanna. Many of our unique features could be attributed to that, including our ability to control breathing, our dive reflex, and our subcutaneous layer of fat which insulates us from greater heat loss when surrounded by water. I don’t know what became of the notion, but it purported to explain many odd things about us.

The Aquatic Ape.
I have the book. Fascinating. Sure, it might be complete nonsense, but it was fascinating stuff.

There’s a good selection of videos on youtube also, if you search “aquatic ape.”
