POUL 3123 - LECTURE 1 2. Introduction to Animal Behavior Levels of Analysis: - Proximate causes (mechanisms – HOW?) Is the behavior heritable? Is the behavior modified by experience? Which hormones influence the behavior? How does the nervous system produce the behavior? - Ultimate cause (WHY?) How is the behavior related to the reproductive success of the individual? What is the evolutionary origin? *Integrative biology – approaches a question from both angles 3. Scientific Method - Develop a causal question about something that has been observed (what is the cause of this?) - Develop a hypothesis to explain the observation (Null hypothesis = hypothesis is not true.) - Generate predictions or expected results - Test the predictions - Generate a scientific conclusion – NOT PROOF! JUST SUPPORT! *In science, we are not trying to prove a point. We are trying to knock down current

Unformatted text preview: scientific hypotheses! For example, a current theory out there is that we evolved from primate ancestors. If we accepted a scientific study as proof, we would no longer be studying this. However, this is now a bigger field of study than ever, and every scientist working on this is trying to disprove the theory. Regardless, most of the data support the validity of the theory. But scientists will never stop trying to knock it down. That is our job, and is why science is so strong. Scientific Method Example: Preferential egg expulsion by house finch females Overall Question – why do females reject some eggs and not others? Brainstorm on potential possibilities Select one possibility and state your question: Make a hypothesis Design an experiment to test it Use results to accept/reject that hypothesis Draw a conclusion...
