1. Evolution Evidence for Evolution

2. Other Evidence for Evolution: Adaptations – Camouflage, Mimicry Fossils Anatomy Embryology Biochemistry – DNA Evidence

3. Example: Camouflage adaptations of mantids that live in different environments… Structural adaptations have been observed in populations of birds, insects, and many other organisms.

4. Adaptations: Camouflage Scorpion fish Hi!

5. Adaptations: Mimicry katydidmoth caterpillar

6. Adaptations: Mimicry monarch butterfly viceroy butterfly

7. Analyzing Fossil Evidence Fossil: a trace of a long-dead organism Biological diversity: many different fossils found showing different species or subspecies. Episodic speciation: time when a large number of species appear Mass extinction: brief periods in time where large numbers of species disappeared (Ex: dinosaurs)

8. Fossils Elephant evolution based on fossils The fossil record provides evidence for the theory of evolution.

9. Sedimentary Fossil Formation

10. Pair Share In your own words, explain how mimicry is different from camouflage.

11. Anatomy: Forearm bones in mammals similar in function and organisms do share common origin.  Homologous structures: similar in function and organisms do share common origin.

12. Homologous structures

13. Anatomy: Analogous structures: similar in function, but organisms do not share a common origin. Example: Insect wings and bird wings.

14. Anatomy: Vestigial structures : body parts that have lost their function over time and are now useless. Examples: human appendix

15. Embryology: Vertebrate embryos are similar, pointing to common origin.

17. Developmental homology Embryology

18. Biochemistry Biochemistry: Similarities in DNA sequence and thus amino acid sequence point to a common origin. The fewer the differences, the more closely related two organisms are. Cladogram: Visual way to show how closely related species are.

20. Pair Share Refer to the illustration. The bones labeled A are known as a) vestigial structures. b) sequential structures. c) homologous structures. d) fossil structures.

21. Pair Share Evidence for evolution includes all of the following except a) some members of the same species show different traits. b) similarities and differences in protein and DNA sequences between organisms. c) the fossil record. d) homologous structures

22. Pair Share The occurrence of the same blood protein in a group of species provides evidence that these species a. evolved in the same habitat. b. evolved in different habitats. c. descended from a common ancestor. d. descended from different ancestors.
