OT: I was reading this article about a potential "real" sixth sense that humans may easily develop: echolocation
https://getpocket.com/explore/item/humans-could-develop-a-sixth-sense-scientists-sayThe thought occurred: maybe we already had it when we were hiding in caves under a low/flickering light and then "lost" it.
Some deep caves in South Africa were continuously occupied by H. sapiens for as long at 100000 years or even longer.
It would make sense to develop such 'sense' back then.
Oh. I had not really thought about our evolution like that, because I was thinking that we probably need sunlight and warmth, and I was thinking that caves were not very warm, but then when I looked up the information, it appears that caves might not be so cold as long as they are generally in a warmer climate... in other words the
caves tend to be as warm as the average annual temperature for the region.
Would be cool if this was pinned on the site.
Pin homer on the site?
That is not very nice of you to have those kinds of thoughts.
