Anatomically Modern Humans Flashcards
Ultimate causation
Why a prototype was naturally selected
Proximate causation
What is immediately responsible for a phenotype
What is another way of explaining ultimate causation?
Why it exists
What is another way of explaining proximate causation?
How it works
Out of Africa Theory
The idea that we mostly descended from a small group of Africans that was nearly wiped around 75,000 years ago
What kind of evidence is there for the Out of Africa theory?
- Fossil evidence
- Genetic evidence
- Inbreeding of early modern humans and Neanderthals
How can we estimate the last common ancestor?
Molecular clock estimation
Molecular clock estimation is based on what theory?
Neutral theory
Neutral theory
Most DNA change is selectively neutral
Anyone of non-African descent currently carries what % of Neanderthal DNA?
2.5%
Anyone of melanesian descent currently carries what % of Denisovan DNA?
5%
Anyone of original African descent carries what % of Neanderthal and Denisovan DNA?
0%
