Though we don’t fully understand why people sleep, there are some solid, quality theories that scientists are working with.
For example, recent research suggests that the primary purpose of sleep for humans may be to remove toxic and metabolic waste from the brain.
According to one perspective article, if these toxins are allowed to build up, they might compromise brain functionality.
Meanwhile, researchers at the Washington University School of Medicine in St. Louis found that during sleep, brain cells propel fluid into, through, and out of the brain, cleaning it of waste.
“These neurons are miniature pumps. Synchronized neural activity powers fluid flow and removal of debris from the brain. If we can build on this process, there is the possibility of delaying or even preventing neurological diseases, including Alzheimer’s and Parkinson’s disease, in which excess waste – such as metabolic waste and junk proteins – accumulate in the brain and lead to neurodegeneration,” explains neurologist Li-Feng Jiang-Xie, PhD, first author and postdoctoral research associate in the Department of Pathology & Immunology.

Lots of theories, but no real evidence and no one has any idea who did it.
Kudos to the people involved for actually keeping their mouths shut for 40 years. Makes me think it was one person that did it all on their own. What are the chances of more than one person keeping a lid on that?
On the one hand, I want the guy(s) who did it to come out and admit it and how they did it. Statute of limitations has to be up right?
But I get why they don’t. I’m sure the Feds would find some way to convict them of something if they came forward, statute of limitations be d****d.

“It is critical that the brain disposes of metabolic waste that can build up and contribute to neurodegenerative diseases. We knew that sleep is a time when the brain initiates a cleaning process to flush out waste and toxins it accumulates during wakefulness. But we didn’t know how that happens. These findings might be able to point us toward strategies and potential therapies to speed up the removal of damaging waste and to remove it before it can lead to dire consequences,” notes Jonathan Kipnis, PhD, the senior author on the paper, the Alan A. and Edith L. Wolff Distinguished Professor of Pathology & Immunology, and a BJC Investigator.
According to Kipnis, if you can enhance the cleaning process in the brain, it would be possible to sleep less and remain healthy.
“Not everyone has the benefit of eight hours of sleep each night, and loss of sleep has an impact on health.”

I have brain cancer, and when I was first diagnosed with it I asked how it happened and my doctor shrugged and told me that they don't really understand how brain cancers develop and that we are just stepping our toes in the door for treatment for it.

Also, how does something evolve to learn how to do that?

We can point to anecdotes regarding how different animals do it, and even the benefits that come from sufficient sleep.
We have some good ideas about what sleep does for the body, along with theories as to why this is a necessity. But in terms of a definitive answer, things seem kind of murky.
