Biology EOC RC3-P1

Mutation any change in the sequence of the bases in DNA
evolution the process of changing over time
natural selection nature picks the best traits; more helpful traits become more frequent in a population when there are more offspring than resources
fitness the ability to survive to reproduce and pass on your genes
analogous structures body parts with similar function but not similar structure; they do not point to a recent commom ancestor
homologous structures body parts with similar structure that point to a commom ancestor
stasis or genetic equillibrium genetic stability, staying the same genetically
punctuated equilibrium short periods of rapid change
mimicry One species evolves traits to resemble another species
recombination an offspring's genetic information is a mix of the mother and father
adaptation an existing inheritable trait that allows an organism to better survive under current conditions
vestigial structure anatomic structure that no longer functions in modern organism but served a function in ancestor; it is evidence of evolution
biogeography study of where modern and ancestral organisms lived
Molecular Record comparing DNA, RNA, or proteins to identify # of differences in order to determine relatedness
Molecular Clock uses mutation rates in DNA to determine the amount of time that two species have been evolving independently
