Children are Smarter Than Adults

This precocity of childhood may be said to characterise all the known races of man, and to be even more marked the more primitive the race. On this point, ‘It is an interesting fact,’ says Havelock Ellis (183, p. 177), ‘and perhaps of some significance, that among primitive races in all parts of the world, the children, at an early age, are very precocious in intelligence.’ And again, ‘ It seems that, the lower the race, the more marked is this precocity, and its arrest at puberty. ...

 Prolongation of Human Infancy

Professor Butler’s discovery, however, was itself anticipated by Burnet in his Early Greek Philosophy (95, p. 74) by a couple of years. Burnet, after quoting the Theophrastean account of the sp...

 Breast Feeding Fuels Big Brains

The study looked at the average pregnancy term, breast-feeding length and brain size of 128 species of mammals. They saw that between different species brain size at birth was determined by the length of pregnancy, while the brain growth after birth was determined by breast-feeding duration. [...] The extreme length of pregnancy and breast-feeding in humans (nine months and three years, respectively) is required for the growth and development of our large brains, which can reach 79 cubic in...
