Cultural Anthropology
The study of human societies, especially in a cross- cultural context; the subdivision of anthropology that includes ethnology, archeology and lingustics
natural selection
the process by which some organisms, with features that enable them to adapt to their environment, preferentially survive and reproduce, therefore increasing the frequency of those improving "fitness" features in the population
biological approach
studying humans in terms of the interaction between biology and culture in evolutionary adaptation
Define Proximal/Distal
proximal (limbs) - towards the torso, distal (limbs) away from the torso
Percussion Flaking
striking one stone with another to break pieces off
A gradual change in the frequency of genotypes and phenotypes from one geographical region to another; parallels a gradient in the environment.
4 Subfields of Anthropology
Cultural, Archeology, Linguistic, and Biological
Homeobox Genes (Hox genes)
direct segmentation/patterning of the body during embryonic development
Salmon mating
competition to reproduce is so intense that it's worth destroying the body to do it, our bodies may be designed in part to be dispensable, death may be part of the design, whether you are stronger healthier or more resistant to disease, there are only relevant if they aid reproduction
The phylum of the animal kingdom that includes vertebrates.
Jean-Baptiste Lamark (1744-1829) concepts
--coined the term "biology"
--1st theoretical attempt to explain mechanism of evolution
--interaction between organism and environment
--theory of acquired characters
--"vital essences" respond to external stimuli
Parallel Evolution
occurs in species that are closely related
similar characteristics due to recent common ancestory
chronometric dating
a dating technique that gives an estimate in actual numbers of years
tooth comb
when incisors protrude from the front of the mouth to form a comblike surface. occurs in Stepsirhine and prosimians
relative rate test
a means of determining whether molecular evolution has been occurring at a constant rate in two lineages by comparing whether these lineages are equidistant from an outgroup
________ is the process of 2 parent cells ending with 2 daughter cells. Daughters have 46 each
with in a species, a community of individuals where mates are usually found.
structural genes

RNA differs from DNA because...
1. Usually single stranded

a group of islands in the Pacific off South America; owned by Ecuador; known for unusual animal life where Darwin found the fiches that led him to the theory of evolution
High vasodilation and effective sweating (e.g., earlier onset, better distribution) maintenance of core temp (even during activity)

Conditions that favor sexual reproduction
trade off fast reproduction for getting new variations, new combinations, one can shift from the second condition (unpredictable) to the first (predictable)

What has a brain size of ~900 cc?
  Homo erectus
DNA Replication
when a cell divides, the DNA must make copies of itself so that each new cell receives a full complement of the genetic code.
Where were primates found during this period and what happened to them?
Africa, Europe, Asia. Broadly distributed, sivapithecus gave rise to orangutans
Stabilizing selection
a plant that is too small (no sun) or too tall (not enough resources) won't do well, ones that are in the middle will end up doing the best, true for most species, humans

A bony ring encircling the lateral side of the eye but not forming a complete cup around the eye globe
What is significant about the date of 2.5 MYA?
First homos and tool makers
Loss of vitamin c synthesis
non functional human gene for LGO (an enzyme essential for endogenous synthesis of vitamin C), human gene for making LGO has mutated to the point that it is now a pseudo-gene
Ch 8: Fossils
Daughter Isotope (product)
The isotope that is produced as the result of radioactive decay of the parent isotope
