Hypotheses of Bogin (1999) p. 225-267:
1. Growth during childhood and juvenile periods sensitive to environmental factors whereas growth
in adolescence determined by genetics
a. in general terms: environmental factors outweigh genetics in childhood and juvenile
stages and in adolescence, it’s vice versa
2. Girls have buffer against growth sensitivity to environmental factors (growth less likely knocked
off-track than boys)
a. Supported by similar growth velocity between Mayan and Ladina girls despite one’s
growth beginning later than the other
b. Buffering + genetics = going through adolescence faster
