Biology Chapter 13 Worksheet 1. Define taxonomy. the science of classifying organisms 2. in the Linnaean system each species is given a two part name or ___binomial____. 3. The first part of the two part name is the _genus____. 4. The second part dis used to distinguish species within a _species__. 5. The example for a leopard is ___panthera pardus_______. 6. The first letter of the genus is ___capitalized____. 7. The whole name is _italicized_. 8. This solved the problem of the ambiguity of common names___ 9. This system also introduced a system for grouping species into a ____hierarchy____ of categories. 10. The grouping starts with a species then a genus then __species____ 11. Then _orders____ 12. Then __class_____ 13. Then __phyla_____ 14. Then __kingdom____ 15. Then ___domains____ 16. Define fossils. Fossils are formed when organisms are trapped in sediments or environments where their shapes are preserved 17. Lamarck explained evolution as the ____ refinement of traits that equip organisms to perform successfully in their environment_______. 18. Darwin traveled the world and collected and journaled his accounts. He noted the characteristics of pants and animals that made them well suited to such diverse _environments___. 19. many of his observations indicated that _geographic___ proximity is a better predictor of relationships among organisms than similarity of environment. 20. After his voyage and discussions with other colleagues he concluded that the evidence explained that present day species are the descendants of __ancient______ _ancestors_______. 21. He concluded that evolution was due to differences accumulated over time by a process called _decendants______ with __modification____. 22. He also proposed a scientific mechanism for how life evolves a process called __natural___ __selection____. 23. This was based on survival due to a species inherited _traits more likely to survive and reproduce_____.

24. This resulted I diverse modifications known as _evolutionary__ _adaptation__ that fit to a specific way of life in their environment. 25. define paleontologist. Scientist who studies fossils 26. Darwin acknowledged the fossil record is ___incomplete_______. 27. This is attributed to? Many organisms did not live in areas that favor fossilization. 28. Define homology. Similarity in common ancestry 29. Darwin claimed that anatomical similarities were evidence of common _ancestry___. 30. The difference in anatomy over millions of years allowed for _adaptation__ of the anatomy to do different functions. 31. Evolutionary history of each species is documented I the _DNA___ inherited from its ancestors. 32. Molecular comparisons between diverse organisms have allowed biologist to develop and test hypotheses about the evolutionary divergence of major _branches___ on the tree of life. 33. Darwin hypothesized that all life forms are related and molecular biology is evidence because all forms of life use the same genetic language of _RNA____ and _DNA__ to make amino acids. 34. define vestigial structures. Remnants of features that served important functions in the organism’s ancestors. 35. Observing early stages of development in different animal species reveals __ the common ancestor of all species that descended from it______. 36. Evolutionary trees are hypotheses reflecting our current of patterns of __evolutionary_ _decent____. 37. define artificial selection. The selective breeding of domesticated plants and animals to promote the occurrence of desirable traits in the offspring 38. What are the two essential components of artificial selection? Variation and heritability 39. He noted the production of more individuals than the environment can support leads to a struggle for existence with only some offspring surviving in each __generation_______. 40. He said that changes in environment leads ultimately to a completely new __species____ over time. 41. new alleles originate by _mutation___, a change in the nucleotide sequence of DNA. 42. In multicellular organisms only in cells that produce gametes can these be passed to offspring and affect genetic variability. mutation 43. Most mutations are _prokaryotic___. 44. Define population. . A group of individuals of the same species that live in the same are interbreed. 45. The evolutionary impact of natural selection is only apparent in changes in a __population___ of organisms over time.
