  1. Study of Life Themes & Concepts Based on work by Foglia, Goldberg

  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 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 Charles Darwin

  8. Natural selection • Evolutionary adaptation is a product of natural selection

  9. Unity and 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 and 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. Levels of organization

  14. Form follows function • Structure & function are correlated at all levels of biological organization

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

  16. 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

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

  18. Big Idea #4 Biological systems interact, and these systems and their interactions posess complex processes

  19. Regulation • Regulatory mechanisms ensure a dynamic balance through feedback

  20. Interdependence • No organism is an island standing alone

  21. Science, technology & society • Science & technology must function within the framework of society • bioethics

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

  23. Science as a process of inquiry • repeatable observations & testable hypothesis
