Do we have the largest brain (in size) of any living or lived creature on earth?
According to Bystander's chart (excellent, BTW!), sperm whales (Genus: Physeter).Biology said:than who has the biggest brain...
We are tops in brain mass relative to body mass, however, according to that chart. Although Grampus (dolphins) are amazingly close.Moonbear said:According to Bystander's chart (excellent, BTW!), sperm whales (Genus: Physeter).

The brain to body proportions uses a metric called the "encephalization quotient". Humans have the highest encephalization quotient or "EQ" at around 7, meaning our brains are about 7 times larger than what would be expected based on our body size.misskitty said:I would expect that a certain species of whale to have a brain larger in size than ours, purly just because they are massive compared to us. It wouldn't be proportional for them to have a tiny brain the size of a walnut. I know are brains are larger than walnuts, but you understand what I mean.
You are also probably familiar with the fact there were many hominoids until something happened, begining about 50,000 years ago. Although nothing much happened in the preceeding million years, suddenly one group "exploded" Out of Africa and in only 20,000 years all the others, including the stronger and bigger brained Neanderthals, were gone. The attachment gives a possible reason for this event. It also explains many other things, that do not appear to be related to each other. It is a paradigm shift, well suported by facts, but all such shift meet with resistance as many important people have vested interest in the established theories.Hwarang said:The early cro magnons average cranial sizes 25% larger than todays average human. However the later cro magnons had smaller head sizes until eventually we have what we have today. Of course Cro Magnons are humans like us.
