The conversation claims that "humans" have lost an equivalent of a tennis ball volume of the brain. But perhaps a more revealing measure would be weight of brain lost in proportion to the body mass.
Elephants have a much larger brain than us, but smaller when compared to their body mass. (Side note: they are one of the few species that can recognize itself in the mirror)
- bluedanieru 16y agoNeanderthals were bigger and stronger than us, but this transcript only references us in comparison with Cro-Magnons. They're still Homo sapiens sapiens so a difference in body mass of 10% seems large (but then so does such a difference in brain mass).
- Vivtek 16y agoWolves and chihuahuas are the same species, too. Their body mass difference is well over 10%.
- lkrubner 16y agoNot the same species, only the same genus: http://en.wikipedia.org/wiki/Canis http://en.wikipedia.org/wiki/Canis They are related. That does not mean they are the same species.
- Vivtek 16y agoSecond paragraph of this link: "Wolves, dogs and dingos are subspecies of Canis lupus." Did you think I just made it up?
