Nick Szabo 🔑 on Twitter: ""We began to walk upright on two feet maybe between 6 and 4 million years ago. Brains ... don’t start to get large until after 2 million years ago, so for the first two-thirds of human evolution, brain size change wasn’t really a major event." https://t.co/rGIfuDutVg"

  Walking upright made us save a lot of energy that no longer was needed to cool our bodies down. On 4 legs, the back is exposed to sun and use lots of energy on cooling. One important reason we could evolve big brains. #evolution

  That was a hard fork, I guess chimpanzees didn't support it and still run the original protocol.

  NZT-48 has some nasty side effects. Put down the books, have a meal, maybe get some sleep. ;)

  I wish I saw more reports of how existing technology is used for research that’s legitimately designed to further our understanding of how and why our basic functions and systems work. Good stuff.

  Our probable galactic intertwined history largely nullifies this field IMO

  Don't need a big brain to chase the wounded deer until it collapses.
