Fill in the chart below about the types of isolation 17. Type of Isolation Definition Behavioral 2 populations develop different courtship rituals that prevent them from breeding. Reproductive species no longer interbreed and evolve into separate species. Geographic Populations separated by geographic barriers. Temporal Reproduce at different times. Fill in the chart below about the different types of evidence for evolution 18. Evidence for Evolution What does it show us Artificial Selection Selective breeding of plants and animals to promote desirable traits in offspring Fossil record Evidence of when an organism lived on earth, how species evolved and how they went extinct. Anatomy Shows us what the organism looked like and what appendages it may have had Geographic Distribution Gives us an idea of where organism lived and where they may have migrated to over time. Embryology The study of one type of evidence of
evolution is called
embryology, the study of embryos. An embryo is an unborn (or unhatched) animal or human young in its earliest phases. ... In fish they develop into gills, but in humans they disappear before birth
DNA How closely related an organism is to another Fill in the chart below about Darwin’s main ideas 19. Darwin’s Main Ideas Explanation: Natural Selection Process by which organisms that are most suited to their environment survive and reproduce most successfully (survival of the fittest) Genetic Variation Produced in 3 ways, mutation, genetic recombination during sexual reproduction and lateral gene transfer Struggle for Existence Survival of the Fittest Descent with Modification Answer the following questions 20. Lamarck tried to explain evolution, but he was wrong- explain what Lamarck meant by the transmission of acquired traits.
21. What is speciation? What are the types of isolation that can cause speciation
? The rise of 2 or more species from 1 existing species

22. What is convergent evolution Give an example. When different species evolve in similar environments Sharks and dolphins are an example. What is divergent evolution Give an example. Closely related species evolve indifferent environments.
Galapagos finches beaks
24. What is co-evolution? Give an example.
2 or more species evolve in response to changes in each other.
Predator/Prey
relationships is an example 25. What is an example of a vestigial organ in humans appendix. How do you identify organisms as belonging to the same species
organisms belong to the
same species if they can interbreed to produce viable, fertile offspring
27. Explain how insects become resistant to pesticides using the concepts of natural selection. Insects eat on the pesticides and they build traits to become immune, they then pass this trait onto their offspring.
28. What are the three types of natural selection List,
describe, and draw a graph of each type. a. Type of Natural Selection Directional Selection
Decription:
individuals atone end of the curve have higher fitness than individuals elsewhere in the curve
Graph: b. Type of Natural Selection
Stabilizin Selection
Decription: If individuals near the center of the curve have high fitness than individuals at either end Graph c. Type of Natural Selection Disruptive Selection d. Decription: When phenotypes at either end have higher fitness than those in the middle
Graph:
Fill in the Blank 29. The founder of modern evolutionary theory is Charles Darwin. Darwin’s idea that each living species has descended with changes from other species overtime is called Theory of Evolution. The process whereby individuals that are better suited to their environment survive and reproduce more successfully is called
Natural Selection. The two sources of genetic variation are mutations & _
recombinant genes Name Period Desk #:________________
33. Hipbones in a whale (shown below) are an example of
Vestigial Organs. The diagram below shows structures that are _ Homologous Structures. The diagram below shows structures that are Analogous Structures
Circle One 36. If natural selection is the process than evolution is the (Outcome/Purpose/Mechanism)
37. Chimpanzees and Humans have (Similar The Same/Completely Different) DNA sequences.
38. The darkening of the peppered moth population overtime in response to pollution from the industrial Revolution is an example of (Directional/Disruptive/Stabilizing) Natural Selection
39. Variations that are adapted tend to be (Passed/Lost/Skipped)
40. While on the Galapagos Islands Darwin observed finches and how the birds (beaks/eyes/embryos) were different shapes
True or False 41. F All mutations are harmful
42. F All mutations are beneficial
43.
F Mutations occur randomly 44. T Mutations are not random
45. ____
T
____All mutations cause organisms to evolve
46. T To be considered the same species organisms must produce fertile offspring
47. F To be considered the same species organisms only must produce offspring
48. T Antibiotics shift natural selection to favor existing bacteria
49. T Antibiotics change the structure of bacteria, making them resistant
