  1. 1. English natural scientist who formulated a theory of evolution by natural selection (1809-1882), "Father of Evolution"
  2. 4. The study of similarities and differences among structures of living species.
  3. 5. breeding The breeding of organisms for desired characteristics
  4. 9. A change in the nucleotide-base sequence of a gene or DNA molecule
  5. 10. The biological process whereby genetic factors are transmitted from one generation to the next
  6. 11. A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.
  7. 13. A characteristic that improves an individual's ability to survive and reproduce in a particular environment.
  8. 14. The study of gene structure and function.
  9. 15. States that species change over time in response to changes in their environment; all life is related and has descended from a common ancestor; overtime beneficial mutations accumulate and the result is a different organism; beneficial mutations are passed on to the next generation.States that species change over time in response to changes in their environment; all life is related and has descended from a common ancestor; overtime beneficial mutations accumulate and the result is a different organism; beneficial mutations are passed on to the next generation.States that species change over time in response to changes in their environment; all life is related and has descended from a common ancestor; overtime beneficial mutations accumulate and the result is a different organism; beneficial mutations are passed on to the next generation.States that species change over time in response to changes in their environment; all life is related and has descended from a common ancestor; overtime beneficial mutations accumulate and the result is a different organism; beneficial mutations are passed on to the next generation.States that species change over time in response to changes in their environment; all life is related and has descended from a common ancestor; overtime beneficial mutations accumulate and the result is a different organism; beneficial mutations are passed on to the next generation.
  10. 16. Similar in structure but different in function (Ex. human leg and a horse leg)
Down
  1. 2. Similar function but different structure - does not show common ancestry - (Ex: butterfly wing and bat wing)
  2. 3. Change in a kind of organism over time; process by which modern organisms have descended from ancient organisms. (change over time)
  3. 5. Process by which individuals that are better suited to their environment survive and reproduce most successfully; also called natural selection
  4. 6. A structure that is present in an organism but no longer serves its original purpose
  5. 7. The study of the development of embryos from fertilization to birth.
  6. 8. Many different types of organisms in an ecosystem
  7. 12. The slight difference in an inherited trait of individual members of a species.
