“Average cranial capacity was larger”
There has to be more to it tham that, otherwise whales would be on Alpha Centauri by now.
The size of the brain is relative to the body. Assumig. Intelligence simply by overall size is foolish. Larger. Odors need larger brains to process all the information their body is sending them.
Vision for example, is a good example of this. Very little of your eye is actually providing high definition vision.. if you were to double the size of the part of your eye that provided such vision your brain would need to be noticeably larger to just be able to process that extra information.
General rule I have seen is brain size relative to body size, tends to correlate with intelligence. Brain size/body size, the higher that number, genrally the more intelligent the animal appears to be
Whales don’t have opposable thumbs.
