Coevolution Event The process by which two or more species evolve in tandem by exerting selection pressures on each other Speciation Event A lineage-splitting event that produces two or more separate species. Phylogenetic Event The evolutionary development and history of a species or higher taxonomic grouping of organisms. Also called phylogenesis. The evolutionary development of an organ or other part of an organism Homology Event Shared trait among species Mutation A Mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene. Gene Flow is the transfer of alleles or genes from one population to another. Migration into or out of a population may be responsible for a marked change in allele frequencies (the proportion of members carrying a particular variant of a gene). Genetic Drift is the change in the frequency of an existing gene variant (allele) in a population due to RANDOM sampling of organisms. Ex. Earthquake or disaster Artificial Selection The breeding of plants and animals to produce desirable traits Krebs Cycle/Citric Acid Cycle release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into carbon dioxide and chemical energy
