Title: Your thoughts on our brain reduction? Post by: DynV on Dec 13, 2023 The following is the comment I left on Why did our brains shrink? - YouTube (https://www.youtube.com/watch?v=SOgKwAJdeUc):
Quote from: @DynV I suspect that we are similar in metal efficiency, that because our individual mental needs lowered, so did our overall intelligence. I think if we gave unbiased tests to both average modern and larger-brained human ancestor, the latter would fare better. However we can't take away the environment, so both would be as efficient. We don't need to remember so much for our survival, all game and harvest patterns, all the waterholes to avoid, the predators large dens, the deadly flora, the other clans limits are and their status (toward our clan), and on & on. Perhaps you agree or disagree with some parts of it.I'm not sure where this belong, I didn't see a forum for human evolution. Title: Re: Your thoughts on our brain reduction? Post by: bio_man on Dec 14, 2023 I can't tell for certain if this is true unless there are more examples of this skull. Furthermore, according to Wikipedia "Around 6% of "Oase 2"'s genome is Neanderthal in origin". And, "Neither "Oase 2" nor "Oase 1" are particularly close genetically to any modern human populations.[11]" Hence, again, we cannot use this as a comparison to modern day human beings.
