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.
- As humans have come to supplement infant feeding with sources other than breast milk, how has that affected energy expenditure?
- Does the energy allocation to reproduction explain the difference in energy expenditure between males and females?
- Are there other kinds of foods that we have special adaptations to digest?
