Lo sostuvo Charles Darwin.

Charles Darwin: After the Origin – Exhibition > The Descent of Man

Allí se lee:

“It has often and confidently been asserted, that man’s origin can never be known: but ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert this or that problem will never be solved by science.” —

(Descent vol. 1, p. 3)
