 Why Humans Evolved to be Active

Humans of all to be much more physically active than our ape ancestors. Typical chimpanzee walks maybe two to three kilometers a day, and they take maybe what, three, 4,000 steps a day. A typical hunter-gatherer takes about 15 to 20,000 steps a day. Per kilo hunter-gatherers spend about twice as much energy per kilo on being physically active per day than our ape cousins. And importantly, that physical activity occurs as we age, right? So Americans are pretty inactive, as we all know. A typ...

The same kind of vocal signals are found in Rhesus monkeys, for example, which have very distin...
