“Intelligent humans developed because our female Homo erectus ancestors had wide hips which allowed them to give birth to babies with big brains, according to Indiana University research in Science.

It is my hypothesis that human evolution occurred because of increases in testosterone (”Androgens in Human Evolution,” Rivista di Biologia / Biology Forum 2001; 94: 345-362 ). In Homo erectus, or a similar species, the female increased in size compared to the male. I suggest this is due to an increase in testosterone in the females.

The consequences of the foregoing is that female pelvis size should decline and the exposure of the fetus to increased maternal testosterone would increase subsequent brain size in the offspring, which would occur after birth. (Please read my article, if interested.) I suggest this pelvis may have existed in H. erectus before H. erectus females increased in testosterone or a subsequent species produced females that increased in testosterone.
