Do you know more intelligent human ancestor were also existed on earth 50000 to 10000 years ago in comparison to today humans!

Cromagnon man ( homosapiens fossillis) cranial capacity 1650cc
Today human brain capacity 1300 to 1600cc ( avg. 1450)!

It was previously thought that intelligent people tend to have larger brains based on an assumption that larger brains contain more neurons and, consequently, possess more computational power but despite their comparatively high number of neurons -- the brains of intelligent people demonstrated less neuronal activity during an IQ test than the brains of the less intelligent individuals.

Intelligent brains possess lean, yet efficient neuronal connections, and boast high mental performance at low neuronal activity.

It’s basically, how the brain is built and the neural pathways, not just the size.

@DarkHeaven yes! Right! I agree! But size also comes in discussion! You know different books write different theories!

@AngelKrish There are always competing theories but Occam’s razor principle holds true. The solution with the fewest assumptions and higher probabilities is likely the truth.

@DarkHeaven Cromagnon man is a direct ancestors of modern man( homosapiens sapiens)!

Brain volumen is needed, but not and far from enough to cause, support and meassure intelligence.
No serious evidences about Cro-Magnons show them as more intelligent humans.
Their descendants, us, had developed what they still could not.

@AngelKrish Worst than only speculative.
Most of knowledge and the structured way we use it is not stored in / by individual biological brains, but in social cultural resources, as are Science, Culture and Civilization.
Which, all of them, are social and not individual.
Besides that, we are the same species.
And they / we evolved in what we are.
Mainly socially: the object of evolution in our case instead of our biology.
And, what are the visible results of such human evolution? Exactly the ones I´ve said, what we have and they do not. The collective store, develope use of cognitive resources. Which is the actual and real meaning of intelligence.

In resume: WE are Cro Magnon, the evolved ones.

@CharlieZ Facts.

@DarkHeaven Yes, those are facts.

Yes I did know that.

@KaiserSolze true reason is their forehead size was much bigger that is the reason during parturation
( while giving birth to baby) female mostly dies!
So female population decreased... No females were left to produce new young ones so they got extinct!

@AngelKrish evolutionary disaster

AngelKrish · 26-30, M

@KaiserSolze ok ok! You are right! Now happy! Fine! Hehe
