All individuals equally likely to mate and surviveThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- Conditions are never completely met if they were met: natural selection would not occurGenetic Drif- Shif in genetic composition of a group/population that you can’t account for- Increase height and robustness of American populationFounder’s effect- Population is established by a very small number of individuals from a larger populationGene flow- New genetic material coming into populations- Movement of organisms from one population to anotherEcological niche- The status of an organism within its environment and community (affecting its survival as a species)Mendel’s Laws1.

Some genes may drop out, get passed on d. Maintain original identity in the individual, you don’t always see them in a person2. Independent assortmenta. Genes do not go from one generation to the next they are passed on independently Primates (order)- Prosimianso 2 classes - Monkeyso Old worldo New world- Apes o Lessero Great- HumansDating- Relative o A way of saying which came for the other thingo Depends on other sites or things or human/animal remains that are before or afer it- Absolute o Chronometric o Not necessarily fixedo Before x and afer yHolistic- All encompassing Artifact- Made by skill- Anything a person made- Relatively portable thing (pots, spear points, things that throw spears, stone tools)Law of superposition - N/O- All of other things being equal, new things on top of old stuff- Before people accepted that the earth went through a series of phases (fires, earthquakes, explosions
