12001200522Natural SelectionA process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.0
12001200523Major points of The Origin of SpeciesEvolutionary change is based on the interactions between populations and their environment which results in adaptations (inherited characteristics) to increase fitness. 1. Adaptations 2. Overproduction1
12001200524EvolutionChange over time in the genetic composition of a population.2
12001200525Evolutionary AdaptationsA genotype of inherited traits that enhance an individuals ability to survive and reproduce in a particular movement.3
12001200526TaxonomyThe scientific study of how living things are classified. Created by Linnaeus.4
12001200527AristotleLife forms arranged by complexity. Believed in Creationism and Natural Theology.5
12001200528Natural Theologytheology or knowledge of God based on observed facts and experience apart from divine revelation. Studying nature6
12001200529Linnaeusfounder of taxonomy; binomial nomenclature7
12001200530CuvierPaleontologist; look into strata; believed in catastrophism.8
12001200531CatastrophismCatastrophe destroyed many living species then immigrant species repopulated9
12001200532HuttonGradualism. earth is millions of years old, major changes are caused by small changes over time. Continuous process.10
12001200533LyellUniformitarianism; Earth processes same rate since the past. Earth is old.11
12001200534LamarckPublished Theory of Evolution in 1809. 1. Told of Inheritance of Acquired Strengths. 2. Use and Disuse12
12001200535MalthusEconomist; More babies are born than deaths.13
12001200536Charles DarwinOrigin of Species. Descent with modification.14
12001200537Voyage of the Beagle1831 trip around the world- mainly Galapagos Islands.15
12001200538Alfred WallacePublished his own theory of evolution by natural selection about the same time as Charles Darwin16
12001200539Artificial SelectionBreeding organisms with specific traits in order to produce offspring with identical traits.17
12001200540Darwin's Mechanisms of EvolutionDescent with Modification18
12001200541Homologous StructuresHave similar structures from common ancestors, but serve different functions. Ex: human arm, bat wing19
12001200542Vestigial StructuresA structure that is present in an organism but no longer serves its original purpose20
12001200543Analogous Structuressimilarities among unrelated species that result from convergent evolution. Ex: Wings for flying21
12001200544Molecular homologiessimilar molecular composition of proteins, DNA22
12001200545convergent evolutionProcess by which unrelated organisms independently evolve similarities when adapting to similar environments.23
12001200546Biogeographystudy of the distribution of organisms around the world24
12001200547Endemic SpeciesSpecies that are native to and found only within a limited geographic area.25
12001200548embryonic homologiesComparison of early stages of animal development reveals many anatomical homologies in embryos that are not visible in adult organisms26
