Natural Selection
|
Idea by Charles Darwin, survival of the fittest
|
|
Evolution according to Darwin
|
Experiment on Finches, decided new species come into existence for adaptation purposes
|
|
Evolution according to Wallace
|
Species create species, natural selection means most suited to the environment will survive to reproduce
|
|
Evolution according to Lamark
|
"Use it or lose it" (giraffes), abandoned idea since it ignores genetic mutations or DNA
|
|
Fossil
|
once living remains of organisms encrusted in the earth (a limited resource that is easily disrupted and incomplete)
|
|
Radioactive dating of fossils
|
there's Carbon 14 in all living and dead organisms, fossils are dated by half lives of Carbon 14
|
|
Analogous Structure
|
2 different structures but the same function
|
|
Homologous Structure
|
2 of the same structures but different functions
|
|
Gene Pool
|
The available alleles in one's environment
|
|
Genetic Drift
|
a change in the Gene Pool due to random mating, no immigration of males, no emigration of females, long periods of time
|
|
Hardy Weinburg equations
|
p^2 + 2pq + q^2, measures equilibrium of gene pool over generations
|
|
Species
|
similar characteristics, successfully interbreed to produce fertile offspring
|
|
Gradualism
|
gradual, small changes to a species over a long period of time
|
|
Punctuated Equilibrium
|
large jumps/changes, rapidly, with periods of no change
|
|
Adaptive Radiation
|
branching from one source, survival of fit; evolution of many branches of organisms from one source
|
|
Latin names
|
italics or underlined, genus and species
|
|
