1) As I said I think brain size is not related to specialisation. Now we know that by specialisation you actually meant our 'abilities'. This of course I cannot dispute; but then my comment on brain sizes and cognitive abilities was not so misplaced in the end, was it?
It is misplaced in some form, as in the start i never said anything about cognitive abilities. But that in itself cause my argument to become wrong, isn't it?
2) You say our brain capacity was the largest compared to other Homo species, "losing only to Neanderthals". How then do you explain that our abilities were more advanced than theirs?
This could be explained by your article on synaptic density. But if there is no such article, then i would say that we Homo Sapiens have both a lucky break to discover those things i have already mentioned and a more refined social abilities.
You just explained that they do, only to say that they don't.
What i really trying to imply is that because "abnormal" literally meant "not normal" or "out of place", then in order to say Humans have abnormally small bodies, you will also have to reasonably imply that the whole primate family tree to also have abnormally small bodies as well, which is pretty far fetched to me
If brain capacity is directly linked to intelligence, sperm whales are ~600% more intelligent than humans.
Hmmmm.............. maybe i mistyped my argument, i forgot to add "in comparison to the whole body", so it's my mistake.
No, they don't. That's purely assumed.
Most of invertebrates have a weak logical thinking processes in the brain. . Most Sponges, cnidarians, coelenterates, worms, arthropods, Molluscs and echinoderms obviously have a very primitive brain if compared to the rest of vertebrates and with it the prefrontal cortex that controls logical reasoning in us. There are some exceptions like the octopus, but because most of the animals that are present in this planet are invertebrates that already implies "most" animals
No. Simple/small â underdeveloped.
You are right, but this was never to imply that simple brains or small ones=underdeveloped brains. so i used the term "and" as just a connection adjective, rather than a causal adjective.
No, it didn't. That's just a flattering, and thus widely held, belief.
Do you really expect me to believe that there ARE other animals with more refined prefrontal cortex than us?
No, they didn't.
Yes, they did. they can't solve complex puzzles that are designed for us, or solve lateral thinking puzzles, yet we can. so we still won.
They do create tools, but their toolmaking abilities are limited to bending and cutting twigs with their beaks and feet.
you are right, so they can't create tools that we make.
Where does this idea come from? As we have no actual knowledge of their mental processes, this cannot be more than speculation.
This idea comes from a fact that in captivity they can hurt other humans even when they live surrounded by people due to unclear reasons. their society is also ones more violent than ours, so they tend to rely on instinct to solve problems with others and to show whose boss ( using violence )
Not really. New languages are created by merging different cultures and dialects over periods of usually several hundred generations, which exceeds any experimental timeline I'm aware of.
So you are implying that dolphins can have multiple languages right? then explain to me why does a dolphin caught in different bodies of water ( like atlantic and pacific oceans) can still communicate with each other
This doesn't even make sense.
Pigs can't recognize itself in a mirror. now does it makes sense?
Do you expect a crow to mine some ore, assemble a lathe, build a forge, and cast a set of tools just to pick a grub out of a hole?
I expect any animals with a complex tool making ability as good as ours to be able to at least capable at creating tools that rival ones from Homo Habilis or Homo Erectus.
Why would they need more than one? All you are doing here is moving the goalposts.
They wouldn't need more than one, but our multiple languages obviously wasn't created because we
need more languages.
