SEXUAL DIFFERENCES IN THE DIMENSIONS OF THE MILK TEETH OF THE CHIMPANZEE AND GORILLA
- 1Comparisons have been made between fifty-eight dimensions of the milk teeth of (a) the male and female chimpanzee, (b) the male and female gorilla.
- 2There is no evidence that the milk teeth of the male chimpanzee differ in size from those of the female.
- 3The milk teeth of the male gorilla are, on the average, 3 per cent bigger than those of the female.
- 4These differences appear before the hormonal factors responsible for the pubertal growth spurt become operative, and may be controlled genetically.
