Dip in body temp as lh spikes. 90% of the variation falls between 4 and 8. No significant interclass difference in the mean or variance in total fertility. All populations with tfr > 8 can be considered colonizing populations. No populations with tfr < 8 can be reasonably classified as colonizing populations. Populations with tfr around 4 have been found to have high levels of. Demography = the scientific study of human population, especially its dynamics, as reflected in fertility, mortality, and migration. ~ 5 million years ago (pair bonding transition) ~ 200 years ago ( the demographic transition) Baby"s head too big to fit when being born.
