  1. Study of Life Themes & Concepts

  2. Umbrella Concepts Big Ideas and Recurring Principles

  3. Why study Big Ideas in 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 (Big Ideas) are fundamental in understanding the nature of living organisms

  4. Big Idea #1 The process of evolution drives the diversity and unity of life.

  5. Organizing Life’s Diversity • Making sense out of the diversity • Hierarchical scheme

  6. Nothing in biology makes sense exceptin the light of evolution. — Theodosius Dobzhansky

  7. Evolution • core theme of biology Yup… I’m da MAN! Charles Darwin

  8. It also shows how ALL life is related to one another! Evolution • evolutionary adaptation is a product of natural selection

  9. ANY Thoughts?? Unity & Diversity • Dual aspects of life on earth • Unity • What do organisms have in common? • Why do similarities exist? • Diversity • What differences are there between organisms?

  10. Unity & Diversity • Unity • evolutionary relationships • connected through a common ancestor • Diversity • natural selection • adaptations in different environments

  11. Big Idea #2 Biological systems utilize free energy and molecular building blocks to grow, to reproduce, and to maintain dynamic homeostasis.

  12. Energy Transfer • life is an open system • organisms continuously interact with the environment • stuff comes instuff goes out • energy is used Entropy rules!

  13. Energy Transfer

  14. Levels of organization

  15. Form follows function • structure & function are correlated at all levels of biological organization

  16. Big Idea #3 Living systems store, retrieve, transmit, and respond to information essential to life processes.

  17. 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

  18. Which science is growing the fastest in new knowledge? MOLECULAR BIOLOGY!! Genomics & proteomicsprojects are driving research

  19. Big Idea #4 Biological systems interact, and these systems and their interactions possess complex processes.

  20. Regulation • regulatory mechanisms ensure a dynamic balance through feedback

  21. Interdependence • no organism is an island standing alone

  22. Science, Technology & Society • science & technology must function within the framework of society • bioethics

  23. Science Practices… Really, what this course is all about!

  24. Science as a Process of Inquiry • repeatable observations & testable hypothesis

  25. Science is a verb! NOT A NOUN! Get ready to do some… Science as a Process of Inquiry

  26. This class is best when there are questions! Any Questions?
