“Simultaneously” is a property of the time dimension, no. 4, and the space dimensions: something happens at the same time in multiple spatial locations.  Now, I thought that there is no such thing as a universal standard time in the universe, only relative time frames, or something.

Dimension no. 5 would be neither space nor time, but a way of…[Read more]

But, Simon, how do I float above it all in a 5th dimension? Or if past, present, and future all exist simultaneously, have I already done so?

If you have ever tried running on uneven surfaces that are loaded with rocks and roots and ready-made to twist your ankles then you know that your brain somehow keeps you safe. But maybe savannah-evolved and savannah staying peoples are not so equipped. Inquiring minds want to know…

I think for instance Sherpas have some special adaptation to handle high altitude.

Yes, I believe they have evolved some extra blood vessels in their lips and some other minor adaptations that allow them survive better in colder climates. When western marathon runners take on the Everest marathon (downhill) challenge, no matter how good they are,…[Read more]

Robert, according to author of linked article the meat in diet leading to bigger brain is a dominant hypothesis but there is also the notion that cooking is linked.

Another major notion is that we have not stopped evolving. Thus what was best for our ancestors is not necessarily best for us. And then it is also true that we are not uniform. I…[Read more]
