Why is it thought that advances such as agriculture, literacy, and urbanization have not been accompanied by additional increase
s in brain size? a. ?the earliest homo sapiens were as intelligent as contemporary humans.
b. ?although brain size has remained constant, brain density has increased.
c. ?more efficient neuronal connections account for modern human advancements.
d. ?the physiological cost of a bigger brain exceeds its benefit?
I think the best answer is D. It is thought that advances such as agriculture, literacy, and urbanization have not been accompanied by additional increases in brain size because the physiological cost of a bigger brain exceeds its benefit. The brain requires a lot of nutrients to function. Having a bigger brain would cost a lot rather than benefiting from it.
The correct answer for this is E. 1.5 x 10^8 because it wants you to convert the answer into scientific notation so if the answer is 150000000 then the answer would be what i said above
This is true and false. It's formulated very confusing. I'd be more inclined to stay the statement is false because the theory of evolution didn't seem reasonable because we didn't know the complexity of living cells but rather because it was in line with the predicitons made by the theory and it made more epistemological sense that did creationism.
Perceptual constancy is the
ability to view or consider an object as unchanged under different conditions
such as changes in distance, physical features or illumination. For the
question above, Immanuel knows the kite is not shrinking due to his brain's
ability to maintain perceptual constancy.
