humans haven't even got the full capacity so the answer is no
normal humans use only 4% of their brains inestein used 10% of his brain.
Yes. Almost all Mammals and Oviparous have brains. Like Humans.
as smart as some humans
well very intelligent they use about 1% of there brains in there life time.
It is a common myth that humans only use 10% of their brains, but in reality, we use all parts of our brain throughout our lifetime. Different tasks and activities engage different parts of the brain, so there is no fixed percentage that represents how much of our brains we use.
The tale that humans do not use the whole of the brains was started by Dale Carnegie author of "How to Win Friends and Influence People" in order to strengthen his case. There is plenty of evidence that humans use the whole of their brains, just not all at the same time. To do so would probably cause us to drop dead instantly from cross-interference of brain function. A massive stroke.
All humans have brains. If you didn't you would be dead and wouldn't be reading this...
The VAST majority of living humans do indeed have working brains, although that fact is not always apparent by their actions.
Monkeys Brains are about 400g were as human brains are about 1400g and are 15cm, monkeys brains are only about 8cm long!
No
No, Humans brains are much more developed. YOU SHOULD KNOW THAT!
That would depend on the animal. Practially all vertebrates have brains, with mammals' and perhaps birds' being the most complex of all. For invertebrates, it depends on the species. Arthropods and cephalopods tend to have brains. Sponges have no neurons whatsoever.
