yes it is true
They don't. Although a dolphin brain is much smaller, it can process a comparable amount of information compared to a human brain.
It is bigger than a non-autistic human brain.
Human
The striped dolphin is considered to be one of the most intelligent mammals. Dolphins have a large brain for their body size. Their brain has the same number of layers as a humans. The dolphin brain has a larger cortex than a human brain.
the only difference between their brains is the size because most humans have bigger skulls than dogs so that allows them to have a bigger brain and the bigger the brain the more your brain absorbs the information.
No, his brain was not bigger than normal. Albert Einstein only used much more of his brain than the normal person. If anyone has a bigger brain than someone else, it is only a difference in the body structure, it does not effect intelligence.
Gross differences are size and shape. The shape of a human skull is bigger because it has a bigger brain to hold. the rodent doesn't have a bigger brain therefore it doesn't need a bigger skull. also the human skull has holes at the back to hold some vertebrates unlike the rodent skull.
The Animal with the largest brain is the Sperm Whale (Cachalot) (Physeter Macrocephalus)
depends. what kind of dolphin?
There is a great deal of evidence that dolphins are second only to primates in intelligence. A recent example is a dolphin that approached a couple of scuba divers to get assistance in removing some fishing line tangled around one of it's fins.
the same as a normal fully grown human's brain. many people believe it is bigger than average due to the fact that humans have accosted bigger with better and Einsteins fbrain is clearly better than ours
A dolphin is a thing, a living thing.A human is a person.
