So it's not all doom and gloom then.
There are certain features in our anatomy that are unique to humans, allowing us to rotate our arms and pelvis, and these are at least partially responsible for our super-charged throwing abilities. Power is all very well, but, compared to other animals, our accuracy is off the charts.
There are many species that can throw, but, for some reason, humans are leaps and bounds ahead of the curve on this one. There was a study in which scientists observed chimpanzees throwing objects and, out of 44 attempts, they only hit the target five times - and that was only at a distance of two metres. Compare this to the average-to-good human who can probably be relied upon to hit another person with a rock from 30 metres.
Incidentally, the whole caving-something's-skull-in-at-a-distance is probably one of the reasons why throwing is a big evolutionary boon for us - allowing us to develop sophisticated hunting techniques without having to engage in hand-to-hand combat with a two tonne bison.
So, we can't remember things, multitask, remain faithful, give birth or poop without risk of injury, but we can catch. So, there's that.
