2. Evidence of Evolution CH 7 SEC 2

3. GOAL/PURPOSE STUDENTS LEARNED THE THEORY OF EVOLUTION. NOW THEY WILL LEARN ABOUT THE EVIDENCE THAT’S SUPPORTS THE THEORY. STUDENTS LEARNED THE THEORY OF EVOLUTION. NOW THEY WILL LEARN ABOUT THE EVIDENCE THAT’S SUPPORTS THE THEORY.

4. FORMS OF EVIDENCE FOR EVOLUTION SIMILAR BODY STRUCTURES, SIMILAR BODY STRUCTURES, PATTERNS OF EARLY DEVELOPMENT PATTERNS OF EARLY DEVELOPMENT MOLECULAR STRUCTURE MOLECULAR STRUCTURE AND FOSSILS ALL PROVIDE EVIDENCE THAT ORGANISMS HAVE CHANGED OVER TIME. AND FOSSILS ALL PROVIDE EVIDENCE THAT ORGANISMS HAVE CHANGED OVER TIME.

7. EVIDENCE CONT’D COMPARATIVE ANATOMY- IS THE COMPARISON OF THE STRUCTURES OF DIFFERENT ORGANISMS. (SEE PREVIOUS SLIDE) COMPARATIVE ANATOMY- IS THE COMPARISON OF THE STRUCTURES OF DIFFERENT ORGANISMS. (SEE PREVIOUS SLIDE) KEY- FISHES, AMPHIBIANS, REPTILES, BIRDS AND MAMMALS ALL HAVE SIMILAR ANATOMY- AN INTERNAL SKELETON WITH A BACKBONE KEY- FISHES, AMPHIBIANS, REPTILES, BIRDS AND MAMMALS ALL HAVE SIMILAR ANATOMY- AN INTERNAL SKELETON WITH A BACKBONE KEY- SIMILARITIES IN EARLY DEVELOPMENT AND IN DNA PROTEINS ARE ALSO EVIDENCE OF EVOLUTION KEY- SIMILARITIES IN EARLY DEVELOPMENT AND IN DNA PROTEINS ARE ALSO EVIDENCE OF EVOLUTION

8. FOSSILS KEY- FOSSILS FORM WHEN ORGANISMS DIE AND BECOME BURIED IN SEDIMENTS. KEY- FOSSILS FORM WHEN ORGANISMS DIE AND BECOME BURIED IN SEDIMENTS. KEY- FOSSIL EVIDENCE SUPPORTS THE THEORY OF EVOLUTION KEY- FOSSIL EVIDENCE SUPPORTS THE THEORY OF EVOLUTION DIFFERENT TYPES OF FOSSILS DIFFERENT TYPES OF FOSSILS 1. MOLDS AND CAST- MOST COMMON 1. MOLDS AND CAST- MOST COMMON 2. PETRIFIED FOSSILS- PETRIFIED FOREST 2. PETRIFIED FOSSILS- PETRIFIED FOREST 3. TRACE FOSSILS- FOOTPRINT 3. TRACE FOSSILS- FOOTPRINT 4. PRESERVED REMAINS- TAR PITS 4.

11. LEARNING FROM FOSSILS PALEONTOLOGIST - IS A SCIENTIST THAT STUDIES FOSSILS PALEONTOLOGIST - IS A SCIENTIST THAT STUDIES FOSSILS THE FOSSIL RECORD - PROVIDES EVIDENCE ABOUT THE HISTORY OF LIFE AND PAST ENVIRONMENTS ON EARTH. THE FOSSIL RECORD - PROVIDES EVIDENCE ABOUT THE HISTORY OF LIFE AND PAST ENVIRONMENTS ON EARTH. KEY- SCIENTIST USE FOSSILS TO STUDY THE RATE AT WHICH EVOLUTION HAS OCCURRED KEY- SCIENTIST USE FOSSILS TO STUDY THE RATE AT WHICH EVOLUTION HAS OCCURRED

12. Theories on how rapidly species change GRADUALISM - PROPOSES THAT EVOLUTION OCCURS SLOWLY BUT STEADILY OVER LONG PERIODS OF TIME. (DARWIN BELIEVED THIS) GRADUALISM - PROPOSES THAT EVOLUTION OCCURS SLOWLY BUT STEADILY OVER LONG PERIODS OF TIME. (DARWIN BELIEVED THIS) PUNCTUATED EQUILIBRIA- SPECIES EVOLVE QUICKLY DURING RELATIVELY SHORT PERIODS OF TIME. SEPARATED BY LONG PERIODS OF LITTLE OR NO CHANGE PUNCTUATED EQUILIBRIA- SPECIES EVOLVE QUICKLY DURING RELATIVELY SHORT PERIODS OF TIME. SEPARATED BY LONG PERIODS OF LITTLE OR NO CHANGE P.E. ACCOUNTS FOR GAPS IN THE FOSSIL RECORD P.E. ACCOUNTS FOR GAPS IN THE FOSSIL RECORD

13. CONT’D KEY- TODAY MOST SCIENTIST THINK THAT EVOLUTION CAN OCCUR GRADUALLY AT SOME TIMES AND MORE RAPIDLY AT OTHERS KEY- TODAY MOST SCIENTIST THINK THAT EVOLUTION CAN OCCUR GRADUALLY AT SOME TIMES AND MORE RAPIDLY AT OTHERS
