five main forces of evolutionary change.
Give this one a try later!
, -mutation: chance changes in DNA
-natural selection: those with alleles that enable them to survive and have
fertile offspring
-gene flow: transfer of genes across population boundaries
-genetic drift: random change in allele frequency over time
-non-random mating: changes genotype frequencies; increases
homozygous, decreases heterozygous
XO: Turner's Syndrome

What happens if there is an error during protein synthesis
Give this one a try later!
, An error such as the addition of the wrong amino acid results in the
production of the wrong protein. This isn't a major issue unless the code in
the DNA itself is wrong.
Explain how all four of the subfields can be considered anthropology.

They all acknowledge the diversity of humankind in all contexts. No other
discipline embraces the breadth of the human condition in this manner.
Also the diverse discipline differs from other disciplines in its commitment
to the notion that unlike other animals, humans are biocultural.

What is the difference between microevolution and macroevolution?
Give this one a try later!
Micro: small scale; within a population from one generation to the next
Macro: large scale; occurs after hundreds or thousands of generations
, What is a heterozygote advantage? What example of this did we have in class?
Give this one a try later!
Sickle Cell Anemia: common in areas with a high incidence of malaria
-Homozygous dominant (AA): become very ill if infected and could be fatal
-Homozygous recessive (aa): most often fatal if infected
-Heterozygous (Aa): little or no instance of malaria infection
*Advantageous because the only population effectively guaranteed
immunity or safety from malaria are those Heterozygous for sickle cell
Adaptive radiation
Give this one a try later!
-A process that occurs when a life form rapidly takes advantage of the
many newly available ecological niches
-Macroevolutionary process
What does it mean to say that anthropology is a science? What does this entail?
