The evolutionist Elaine Morgan admits: “Four of the most outstanding mysteries about humans are: (1) why do they walk on two legs? ( 2) why have they lost their fur? ( 3) why have they developed such large brains? ( 4) why did they learn to speak? ”
Evolutsionist Elaine Morgan märgib: ” Neli kõige silmapaistvamat inimesega seotud mõistatust on: 1) miks nad käivad kahel jalal?, 2) miks neil pole enam karvkatet?, 3) miks neil on arenenud nii suur aju?, 4) miks nad õppisid rääkima? ”
