  1. Curiously, I did not know how you intended “downhill” until I read the article. It can mean either bad (increasing distance from the apex) or good (less difficult travel, as gravity assists), depending on context.

  2. «Historical accounts from the 16th and 17th centuries by Portuguese priests visiting West Africa mention typical chimpanzee behaviours such as nut cracking (palm nut) and the raiding of honeybee nests for honey (Hair 1984; Sept & Brooks 1994)»

    How many great discoveries may have been lost throughout history because the world simply wasn’t ready for them?

  3. It seems to me that the length of time our children are dependent on us enforces our social habits in a clear darwinian sense. Child caring is clearly a selection pressure. Antisocial people are not successful in leaving offspring, and those traits decrease naturally over time.

    This then sets up the second scenario to which you allude in your article – the longer children are around their parents, the more lore they learn. Lore which includes the collected tool using skills of their predecessors.

    I love thinking about how we came about, running down these crazy connections that formed us.

    Keep up the good work turning over those rocks!
