Name Due Date Hour Learning Target: Describe the sequence of events currently hypothesized to have lead to the origin of life on this planet. For each scientist listed below, describe their contribution/answer to the question “Where did life on Earth come from?” 1. Redi 2. Fox 3. Miller 4. Orgel 5. Darwin 6. Oparin True or False 7. Charles Darwin was the first person to think of evolution. 8. Oparin has fully explained how life began on Earth. 9. Darwin’s ideas say that we evolved from Gorillas. 10. Other scientists have modified Darwin’s original ideas. 11. Francesco Redi proved spontaneous Generation was right. 12. How have scientists changed Darwin’s idea that evolution occurs slowly and gradually? For each pair below circle the event that happened FIRST. 13. building blocks join to make macromolecules or macromolecules combine to form protocells 14. evolve the diversity of life now on the planet or macromolecules combine to form protocells 15. gain hereditary information so can reproduce or building blocks join to make macromolecules 16. create the chemical building blocks or building blocks join to make macromolecules 17. create the chemical building blocks or gain hereditary information so can reproduce 18. gain hereditary information so can reproduce or evolve the diversity of life now on the planet 19. evolve the diversity of life now on the planet or building blocks join to make macromolecules 20. macromolecules combine to form protocells or gain hereditary information so can reproduce 21. Why was the path to the first living things a BuMPHE ride? First you needed to make then then gain then so that life could . Learning Target: Support evolutionary theory with evidence. 22. Define Evolution: 23. How do new species evolve? 24. List and describe the six pieces of evidence we use today to support evolution from common ancestors: 25. Match the key of natural selection to the explanation of how the elephant got its tusks. An elephant has two front teeth that grow very large out of its mouth and are called tusks that they use for fighting off predators. Populations have individuals with variety a. There were many elephants and not enough (differences) resources so they competed. Population produce too many individuals so they b. As more time passed, long teeth elephants must compete became a new species. Individuals with best traits survive and reproduce c. Elephant with longer teeth could fight predators, survive and have kids. Offspring will likely inherit the parents’ traits, survive, reproduce and pass on traits d. Over a very long time, the population changed to have elephants with long teeth. Over a very, very long time changes accumulate until population becomes different e. Ancient elephants had long, medium and short length front teeth. As changes accumulate population becomes a new species. f. The kids usually had long teeth, so they’d survive and reproduce kids with long teeth.
