Population, group of organisms of the same species that live in a specific geographical area, Evolution, change in the gene pool over time, Non-Random Mating, The gene pool can be changed by charcteristics which make an individual more or less likely to mate., Mutations, random changes in the gene pool, Adaptations, characteristic that improves an individual's ability to survive and reproduce in a particular enviroment, Microevolution, is a small change in the gene frequency within a population over a short period of time, Macroevolution, Large scale changes in evolution over a larger period of time, Charles Darwin, Developed a hypothesis, which eventually became a theory, of how evolution takes place, Species, a group of organisms that are closely related and can mate to produce fertile offspring, Variations, the occurrence of hereditary or nonhereditary differences between different individual of population, Natural selection, the process by which organisms that inherit advantageous traits tend to reproduce more successfully than other organisms do, 4 parts of natural selections, overproduction, genetic variation, selection, adaptation, Overproduction, producing more offspring than the environment can support, Genetic variation, naturally occurring differences in traits within a species, Extinction, when all members of a species have died, causes of extinction, greater competition, new predators, loss of habitat, natural disasters, Fossils, remains or imprints of once living things, Evidence of evolution, fossils and the fossil record, comparative structures, DNA, embryology, fossil record, all of the fossils that have been discovered, relative dating, determines whether a fossil formed before or after another fossil, absolute dating, estimates the age of a fossil in years., Homologous structures, are structures that are similar in related organisms because they were inherited from a common ancestor., Analogous structures, are structures that are similar in unrelated organisms., vestigial structures, Structures that are remnants of important features that are no longer needed., Embryology, the study of development, Coevolution, when two species evolve together, each one making changes in response to the other, Geographic speciation, when a species is separated by a landform such as mountains, resulting in 2 new species.
