Document Summary

Lecture 2 evolution and natural selection: basic definitions: Evolution change in gene frequency not necessarily better or worse but changes. Genotype the genetic makeup of an organism determines the phenotype at what stage do these phenotypes grow also determines behaviour ex. what kind of web the spider will draw. Phenotype the organisms observable characteristics everything that you use your 5 senses about an organism. Genotype & environment interact to produce the phenotype (g + e = p) environment helps trigger which genes are expressed: gene"s eye perspetive. Genes get passed on and use bodies to pass them on. Genes are replicators build a boy to replicate their gene (vehicle: we are the vehicles anything that will help the gene spread, the body will try to do. How may we try to pass on our genes: build a good body. Reproduce sharp teeth depending on the animal extract info from the environment.
