What was the IQ of ancient man, and his immediate precursors?
Although he couldn't write, read, speak or take a "Mensa IQ test paper" as we understand it, presumably an average homo sapiens of 250,000 years ago by definition had the same IQ of an average homo sapiens of today: ie 100.
Might it have been actually higher than today ie although he knew much less than us, he could make much more intelligent use of what little he had?
More recently, might one say that eg the builders of the Great Pyramid had to have had IQs >140 to pull off such a novel complex structure, without any precedent or previous example to work on, and without any of our amenities?
Presumably for Homo Habilis, Homo Erectus etc the term "IQ" is not applicable, and that Homo Neanderthalis was c90?
Anything lower is what is termed today by psychologists today in the categories of "idiot, cretin, imbecile, retard, moron" etc
