EEA and misc
The definition of an evolutionary mismatch
What is a trait that was adaptive in a different environment with a different selective pressure but is no longer adaptive?
A trait in humans that is responsible for our particularly high energetic demands (compared to other apes)
What are big brains?
General number of offspring per individual in industrial societies compared with non-industrial societies
What is fewer offspring?
This member of the teaching team has scuba dived in the great barrier reef
Who is Professor Lizzy Eadie?
What is an environment or set of environmental factors that selected for a particular trait?
A possible result of the dietary mismatch in western, industrialized societies
What is obesity?
The relationship between energy availability and reproductive hormones
More energy -> more reproductive hormones
This team member once rode on the back of an elephant in Thailand
Who is Savannah?
The sort of stressors that our stress response evolved to handle
What are short, physical stressors?
Evolved responses in humans to high energy demand (give 2)
- Preference for energy-dense foods
- Tendency to store excess energy as fat
- Tendency to avoid exercise when possible
A hypothesis for the lower number of offspring in industrialized societies, despite higher availability of energy and resources
Any of the hypotheses we looked at in class: Industrialization too new, evolved psychologies, lineage preservation, primate life histories, embodied capital
This member of the teaching team was in the Thanksgiving Parade
Who is Jack?
The general EEA that is believed to be responsible for a majority of human traits that distinguish us from chimpanzees and other apes
What is the hunter gatherer niche?
Compare fiber, fat, and carbohydrate levels for ultra-processed foods and wild foods
Fiber -> much higher in wild foods
Fat -> higher in ultra-processed
Carbohydrate -> higher in ultra-processed
Three main reproductive hormones
What are estrogen, progesterone, and testosterone?
The member of the teaching team who is neighbors with Nick Jonas
Who is Tevelle?
What EEA stands for
What is an Environment of Evolutionary Adaptiveness?
A ranking of how much foods increase blood sugar levels
What is the glycemic index?
Explain how the availability of contraception can result in higher risk of reproductive cancers (hint: there should be multiple steps)
Contraception -> fewer pregnancies -> more reproductive cycles -> more cell division -> more mutation
This member of the teaching team spent most of their life in Mexico
Who is Zeni?
