1. AP Biology The Science of Biology  Chapter 1

2. AP Biology Study of Life Themes & Concepts BIOLOGY 114

3. AP Biology Themes  Science as a process of inquiry  Evolution  Energy transfer  Continuity & Change  Relationship of structure to function  Regulation  Interdependence in nature  Science, technology & society

4. AP Biology Science as a process of inquiry

5. AP Biology Science as a process of inquiry  repeatable observations & testable hypothesis

6. AP Biology Evolution  Core theme of biology Charles Darwin

7. AP Biology Natural selection  Evolutionary adaptation is a product of natural selection

8. AP Biology Nothing in biology makes sense except in the light of evolution. — Theodosius Dobzhansky BIOLOGY 114

9. AP Biology Natural selection  Evolutionary adaptation is a product of natural selection

10. AP Biology Energy transfer  Life is an open system  organisms continuously interact with the environment  stuff comes in stuff goes out  energy is used Entropy rules!

11. AP Biology Energy utilization

12. AP Biology Continuity & change  Continuity of life is based on heritable information in the form of DNA  DNA – the genetic material – carries biological information from 1 generation to the next

13. AP Biology Form follows function  Structure & function are correlated at all levels of biological organization

14. AP Biology Interdependence  No organism is an island standing alone

15. AP Biology Science, technology & society  Science & technology must function within the framework of society  ethics

16. AP Biology Umbrella concepts Recurring principles & ideas BIOLOGY 114

17. AP Biology Diversity & unity  Dual aspects of life on Earth

18. AP Biology

19. Unity of life What do organisms have in common? Why do similarities exist? BIOLOGY 114

20. AP Biology Evolution explains diversity & unity  Unity  evolutionary relationships  connected through a common ancestor  Diversity  natural selection  adaptations in different environments

21. AP Biology Properties of life orderreproduction growth & development response homeostasis evolutionary adaptation energy utilization

22. AP Biology Levels of organization

23. AP Biology Each level has emergent properties

24. AP Biology Cell is basic unit of life  Cell theory  developed with early microscopes  prokaryotes  eukaryotes

25. AP Biology Diversity of life What differences are there between organisms? BIOLOGY 114

26. AP Biology 3 Domains of Life Bacteria, Archaea, Eukarya

27. AP Biology Organizing systems  Making sense out of the diversity  Hierarchical scheme

28. AP Biology Why study themes of Biology?  Biology is an ever expanding body of knowledge  too much to memorize it all  need to generalize  create a framework upon which to organize new knowledge  themes are fundamental in understanding the nature of living organisms

29. AP Biology Which science is growing the fastest in new knowledge? BIOLOGY!! Dr. Mary Claire King Genomics & proteomics projects are driving research

30. AP Biology Any Questions?? BIOLOGY 114
