  1. Evolution Review

  2. _____ is a trait may develop quickly – example: antibiotic resistance • Physiological Adaptation

  3. Any body structure that is reduced in function is known as a _______ • Vestigial structure

  4. ______ is the splitting of 1 species into 2 or more • speciation

  5. Similarities in structure and arrangement—likeness indicates a genetic relationship through a common ancestor is known as ______ • Homologous structures

  6. Which type of genetic drift is caused by catastrophic events like a natural disaster or habitat loss? • Bottleneck effect

  7. What is the random effect that can occur when a small population settles in an area separated from the rest of the population and interbreeds, producing unique allelic variations? • Founders effect

  8. A brown mouse blends in with his surroundings. This is an example of ________ • Camouflage

  9. List a vestigial structure in humans. • Wisdom teeth • Appendix • Ear muscles

  10. Change in allele frequencies in a gene pool due to chance is known as _______ • Genetic Drift

  11. Two organisms live in close proximity, but rarely interact due to living in different habitats. This is known as __________ isolation. • Habitat

  12. The environment acted directly on organisms to produce hereditary change in relation to need, use or disuse is known as _____________ • Acquired Traits

  13. _____ is the process in which a large population declines in number, then rebounds • Bottleneck effect

  14. What type of evolution happens in a shorter amount of time? • Microevolution

  15. Who’s theory was based on the idea that the environment acted directly on organisms to produce hereditary change in relation to need, use or disuse. • Lamark

  16. When one organism looks like a dangerous organism, this is a structural adaptation called_____. • mimicry

  17. ___________ is a change in the gene pool of a population in response to various stimuli exhibited by a species OVER TIME • Evolution

  18. It is impossible for a monkey and a lion to reproduce. This is known as____ isolation. • mechanical

  19. Which type of evolution requires speciation? • Macroevolution

  20. __________ may arise over many generations (Ex: mimicry and camouflage) • Structural adaptations

  21. Two species are separated by an ocean. This is referred to as_________ isolation. • Geographic

  22. _________ is evolutionary change below the level of species, and refers to changes in the frequency within a population or a species of its alleles • Microevolution

  23. What is the name of the ship where Darwin did his studies for his evolution theory? • HMS Beagle

  24. Two species of frogs live in close proximity, but reproduce at different times of the year. This is known as ___________ isolation. • Temporal

  25. __________ is any evolutionary change at or above the level of species. • Macroevolution

  26. What organism did Darwin use to base a lot of his evolutionary ideas? • Finches

  27. Two species of birds, meadowlarks, have overlapping ranges and are similar in appearance, but their songs separate them. This is known as_________ isolation. • Behavioral

  28. If a lion and a tiger mate, their offspring is a liger. The liger is sterile and cannot reproduce. This is known as________ isolation. • Gamete

  29. Any trait that aids the chances of survival and reproduction of an organism is known as __________ • Adataption
