“Science is built of facts the way a house is built of bricks; but an accumulation of facts is no more science than a pile of bricks is a house” ― Henri Poincaré My goal is to help you develop the skills to “build” and achieve deep meaningful understanding rather than simply “pile” facts.

INTRODUCTION TO THE WORLD OF BIOLOGY

Biology - The scientific discipline devoted to the study of life What is life? Why is this question so important and why study Biology? Studying the nature of life allows Biologists to seek answers to other “big” questions such as:

Discovery Science - scientists describe some aspect of the world and use inductive reasoning to draw general conclusions. Induction - line of logic where generalizations are derived from a large number of specific observations; ex: “All organisms are made of cells.” Hypothesis-based Science - based on observations, scientists propose hypotheses* (well-reasoned predictions or “explanations on trial”) and subsequently test them by seeing if the predictions are true. Deductive reasoning is used to test a hypothesis. Deduction - line of logic where specifics are derived from general premises; usually takes the form of “If…then” proposals: If a hypothesis is correct, and we test it, then we can expect a particular outcome. *Hypotheses must be testable and capable of being proven incorrect

Biological Organization Follows a Hierarchy

In the course of the semester, we will follow the progression of this hierarchy - a retrospective journey taking a look at how life has evolved, moving from chemical foundations to the intricate and complex processes that maintain life: Biochemical Basis  Aggregation and Interaction Cell Theory Metabolism Replication Inheritance Evolution Biodiversity
