Anthropology 105, lecture 13: Milk

less than 1 minute read

Technical issues caused me to miss lecture 12, which was about metaphyses and the growth of the skeleton, as cues for life history evolution.

Lecture 13 went into “Milk” as a topic. Lactase persistence comes in at the end as a case of gene-culture coevolution. Most of the lecture covers the concept of energy expenditure, including sex differences in basal metabolic rate and energy expenditure and the energy demands of pregnancy and lactation.
