Lithification: The process by which the pressure of sediments squeeze extra water out of decaying remains and replace the voids that appear with minerals from the surrounding soil and groundwater.

Parental investment: Any time or energy a parent devotes to the current offspring that enhances its survival (and eventual reproductive success) at the expense of the parent’s ability to invest in the next offspring.

This is because the frontal lobe of the modern human brain is larger than the one in archaic humans, and the skull has to accommodate the expansion. The parietal lobes of the brain and the matching parietal bones on either side of the skull both bulge outward more in modern humans.

Because extraction of aDNA requires destruction of part of the tissue, and the morphology of the skeletal element might be informative, care needs to be taken when deciding what is sampled.

As the brain’s ability increased, it shaped the skull by reducing the evolutionary pressure to have large teeth and robust cranial bones to produce the modern Homo sapiens face.

Hox genes: A group of related genes that control for the body plan of an embryo along the head-tail axis. Natural selection: A consistent bias in survival and fertility, leading to the overrepresentation of certain features in future generations and an improved fit between an average member of the population and the environment.

Diets high in saturated fat and cholesterol can lead to atherosclerosis, a condition in which fat and cholesterol form plaque inside the arteries, eventually building up and hardening to the point that blood flow is blocked.

For example, how does being a college student influence your eating habits, physical activity patterns, smoking, and consumption of alcohol? Think about how the following industries and institutions might profit from it: The medical establishment?

Why is reduced pigmentation of the skin advantageous for individuals from northern latitudes? Compare and contrast the various genetic mutations of the indigenous Tibetan and Ethiopian high-altitude populations. What is the relationship between the sickle cell mutation and the Plasmodium parasite?

What are the three main explanations for why people in small-scale societies share food extensively? Describe the difference between a proximate and an ultimate explanation and include an example of each. What are two misconceptions about human behavioral ecology? What contemporary world issues can human behavioral ecology help us solve?
