N.B. An acceptable alternative to deductive , hypothesis-driven (“experimental”) science is inductive reasoning (generalize from a large body of consistent observations; e.g., Cell Theory, Atomic Theory).

B.   The Scientific Method:   the scientific method is a step-wise process for experimentation that is used to answer questions and explore observations. Hypothesis:   any proposed explanation for an observed phenomenon.  What scientists do is to propose and then evaluate hypotheses by experimentation or further observation. Theory:   a hypothesis or set of hypotheses that is consistent with virtually all of the available evidence.  Sometimes referred to as a “law of nature”. _2__ observe something _4__ make a prediction _5_ experiment/test __3_ formulate a hypothesis __1_ ask a question _6_ revise hypothesis

tests results not consistent; modify hypothesis *NOTE: scientific “theory”

Why doesn’t this %^$#!& flashlight work??!?!?!? Fig. 1.24 (1.25, 7th) 2. Falsifiability: this means that there must be some experiment or possible discovery that could prove the hypothesis/theory untrue.

C.  Pseudoscience : is indifferent to criteria of valid evidence; - does not emphasize meaningful, controlled, repeatable scientific experiments. - relies on unverifiable eyewitness testimony, stories and tall tales, hearsay, rumor, and dubious anecdotes. - resorts to “magical thinking”:  inexplicable influences and connections between things are assumed from the beginning—not found by investigation. - Genuine scientific literature is either ignored or misinterpreted. (Rory Coker, PhD:   http://www.quackwatch.org/01QuackeryRelatedTopics/pseudo.html ) - Some examples of pseudoscience: Modern geocentrism, astrology, phrenology, graphology, pyramidology

Background image of page 10
COURSE OUTLI NE A.  UNIT I:   Development and Cell Differentiation genes  control development B.  UNIT II:   Mendelian Inheritance genes  are inherited - differential inheritance of  genes  generates   diversity in offspring C.  UNIT III:   Evolution gene  frequencies change in populations over time - new species arise as  genetic  differences accumulate D.  UNIT IV:   Ecology - the interactions of organisms with each other and with their environment are often under  genetic  control - genes interact with & can be affected by environment
