pages 56-63- intro to human evolution
introduction: our place in nature!
-the theory of evolution by Darwin is among the cornerstones of modern science.!
-species: group of organisms that can produce fertile ospring
-all living humans are members of the species homosapiens which belongs to the
genus homo. !
-hominoids: biological superfamily that includes humans, great apes, and
-humans also belong to the order primates. !
-humans did not evolve from apes, humans and apes evolved from a same
common ancestor !
-phylogeny is the evolutionary history of a species and is based on combination
of info from fossils and genetics !
-genetic evidence
-the path of our growth and development as individuals is the result of interaction
between genetics and environment !
-ontogeny: growth and development of an individual organism !
- nuclear DNA: dna located in the nucleus
-mitocondrial DNA: DNA located outside of the cell nucleus. inherited
exclusively from the mother. !
-DNA evidence can be used to the genetic similarities between species !
-humans are most related to chimpanzees !
-the degree of similarity can be used to infer the timing of the split of lineage
-molecular clock: method that allows the timing of the split between lineages to
be calculated on the basis of the degree of genetic similarity !
