    Endosymbiosis
  4. Development of new types of organisms from preexisting types of organisms over time
    Evolution
  5. Mechanism for descent with modification
    Natural Selection
  6. A trait that makes an individual successful in its environment
    Adaption
  7. Anatomical structures that occur in different species and that originated by heredity from a structure in the most recent common ancestor of the species
    Homologous Structures
  8. Closely related functions but do not derive from the same ancestral structure
    Analogous Structures
  9. Structure in an organism that is reduced in size and function and that ay have been complete and functional in the organism's ancestors
    Vestigial Structures
  10. Relationships by ancestry among groups of organisms
    Phylogeny
  11. Different species evolve similar traits
    Convergent Evolution
  12. Process in which the descendants of a single ancestor diversify into species that each fit different parts of the environment
    Divergent Evolution
  13. Evolutionary pattern in which many species evolve from a single ancestral species
    Adaptive Radiation
  14. Two or more species have evolved adaptations to each other's influence
    Coevolution
  15. Individuals with either extreme variation of a trait have greater fitness than individuals with the average for of the trait
    Disruptive Selection
  16. Individuals that display a more extreme form of a trait have greater fitness that individuals with an average form of the trait
    Directional Selection
  17. Individuals with th3e average form of a trait have the highest fitness
    Stabilizing Selection
  18. Process of species formation; results in closely related species
    Speciation
  19. Physical separation of members of a population
    Geographic Isolation
  20. Results form barriers to successful breeding between population groups in the same area
    Reproductive Isolation
  21. Idea that speciation occurs at a regular, gradual rate
    Gradualism
  22. A model of evolution in which short periods of drastic change in species are separated by long periods of little to no change
    Punctuated Equilibrium
  23. Phenomenon by which allele frequencies in a population change as a result of random events
    Genetic Drift
  24. Change in the collective genetic material of a population
    Microevolution
  25. Principle states that the frequency of alleles in a population does not change over generations unless outside forces act on the population
