  1. 3. Pattern of evolution-when a small group of species diversify into many distinct forms or new species.
  2. 4. Evidence for/pattern of evolution-unrelated organisms will evolve to look similar to environmental demands ex. shark and dolphin
  3. 7. Survival of the fittest those organisms best suited to their environment survived and reproduce proposed by Charles Darwin.
  4. 8. Evidence for evolution-study of the early stages of development in a zygote/developing embryo.
  5. 10. Evidence for evolution-when different structures of an organism are used for similar functions ex. internal structures of butterfly wings vs bat wings vs bird wings.
  6. 12. Large scale change in species, formation of a new species, or change over long periods of time (millions of years)
  7. 14. Pattern of evolution-when a species is no longer present on earth.
  8. 15. Fertilized egg,embryo of a new developing organism.
  9. 17. Evidence for evolution-collection of fossilized remains that show changes in organisms through geologic time.
  10. 18. Evidence for evolution-random neutral mutations accumulate in the genome of a species and can be used to determine how long ago an evolutionary split between species occurred.
  11. 19. Pattern of evolution-long periods of genetic equilibrium interrupted by periods of rapid change.
  12. 20. Pattern of evolution-when 2 species that closely interact evolve in response to one other/together over time.

  1. 1. Evidence for evolution-unused structures or organs in an organism that are remnants of ancestral species.
  2. 2. Newly adapted/evolved characteristics, used to separate species/taxonomic groups on a cladogram.
  3. 5. Small scale changes in allele frequencies in a population.
  4. 6. 2 part scientific naming system used to identify organisms.
  5. 9. Evidence for evolution-master control genes that determine placement of limbs/organs and development in organisms.
  6. 11. Section of the evolutionary tree that shows derived characteristics and ancestral/evolutionary groups of organisms.
  7. 13. Scientific classification that organizes living things into related categories ex.domain, kingdom, phylum, class, order, family, genus, species.
  8. 16. Evidence for evolution-when the same structures of different species are used in different ways ex. bones of a bat used to fly while bones of a horse used to run.
