10. sedimentary Do Now frozen amber ___ layers of rock and sand through weathering can bury the dead organisms quickly to become a fossil. Two types of fossils that are not in sediments are ___ and ___. Four places that we find fossils are: ___ sea floor, lakes, rock intertidal (between rocks and ocean) and __ forests. ocean rain

11. Do Now amphibians evolved The geological time scale is divided into eras and periods, and finds that fish, ___ , reptiles, mammals and bird, and lastly humans ___ in that order. 2. This was determined by digging the earth up and finding that the bottom layer is ___ while the top layer is ___ (most recent). older younger

12. Do Now Paleozoic Look at the geological time scale on page 346, the Precambrian period (4.6 bya) includes bacteria. The ___ period (545 mya) includes fish, land plants, amphibians, and reptiles. The Mesozoic period (245 mya) includes mammals and birds and ___ plants. The Cenzoic period (65 mya) includes ___ . flowering humans

13. Do Now There are indirect evidences that evolution did occur: All animals (fish, amphibians, reptiles, birds and ___ ) have similar embryonic stages. The chemical makeup of all organisms include ___. The way organisms developed into ___.

14. a. All animals (fish, amphibians, reptiles, birds and ___ ) have similar embryonic stages. mammals

15. b. The chemical makeup of organisms include ___ . Deoxyribonucleic Acid

16. All organisms not only have DNA but the DNA of some organisms are closely related to one another.

17. c. The way organisms developed into ___ . adults Upper arm Lower arm Lower arm

18. homologous Do Now __ structures are similar in origin, structure, and function. For example: the arm of a human, leg of a cat, flipper of a whale and wing of a ___ are homologous structures. ___ structures are structures that do not seem to have a function. For example: wisdom teeth, ear muscles, tailbone, and ___ are vestigial organs.

19. 2. For example: the arm of a human, leg of a cat, flipper of a whale and wing of a ___ are homologous structures. bat

20. 3. ___ structures are structures that do not seem to have a function. vestigial

21. 4. For example: wisdom teeth, ear muscles, tailbone, and ___ are vestigial organs. appendix

22. analogous Do Now ___ structures are animals with similar functions and form but have different embryonic development. For example: the ___ of a butterfly, pterodactyl, bird, and bat is used for flying but they are all developed differently. Therefore these animals do not share a ___ ancestor.

23. 2. For example: the ___ of a butterfly, pterodactyl, bird, and bat have is used for flying but are developed differently. wings

24. 3. Therefore these animals do not share a___ ancestor. common

25. DNA Do now Similar ___ is the molecule that carries genetic information of a cell and controls the developmental process. ___ DNA can suggest common ancestry between different species. For example, ___% of DNA is shared between humans and chimpanzees. While ___% of DNA is shared between humans and bananas.

26. 3. For example, ___% of DNA is shared between humans and chimpanzees. 98 There is only 2% difference between the DNA of humans and chimpanzees. 92% DNA is shared with humans and mouse.

27. 4. While ___% of DNA is shared between humans and bananas. 50

28. Do Now Identify each slide as either a homologous, analogous or vestigial structures. Since animals of ___ structures came from a common ancestor and, through natural selection, were modified to perform different ___. Since ___ and ___ structures have internal differences, they might not have shared a common ancestor.

29. 2. Since animals of ___ structures came from a common ancestor and, through natural selection, were modified to perform different __ homologous functions.

30. 3. Since ___ and ___ structures have internal differences, they might not have shared a common ancestor. analogous

31. 3. Since ___ and ___ structures have internal differences, they might not have shared a common ancestor. vestigial analogous

32. 4. human= arm for pushing and pulling Mole= forelimb for digging Anatomical evidence worksheet Tree shrew= forelimb for climbing Sea lion= flipper for swimming

33. Homologous1. the functions are ___. 2. The shoulder is attached to an ___ and then __. 3. 4. It depends on the animal’s environment.

34. Analogous 5. The wings are for __. 6. The butterfly has ___ bones on its wings. 7. They have similar ___ but different internal structures. 8. Eyesight is not important because the cave is ___. 9. Yes because both have eyes when they were first evolved.

35. Appendix = digests raw foods = we like cooked meatmuscles that move ears = we need it hear more = eyesight became more importantwisdom teeth = to chew = we use utensils to prevent wear and tear of teeth

36. appendix = to digest raw meats = we like cooked meatmuscles that move ears = to hear = we use our eyesight more little toe= for climbing = we can build ladderswisdom teeth= to help chew = we have better dental care

37. 10. Appendix = digest ___ foods = because humans like ___ meatsmuscles that move = for hearing = we rely more on our ___wisdom teeth = to tear ___ off = we use ___ for steaks
