September 6th: Learned vs. Innate:
While the idea of debating "Nature vs. Nurture" is long passed, our understanding of the the complex interaction of genes and experience to produce the observed phenotype is far from complete. The species specific songs of birds are acquired in very different ways, hence we can draw examples that demonstrate the full spectrum for the relative contribution of nature and environment. For a more mechanistic understanding these interactions we will turn to other model organisms in the upcoming weeks.
The experimental design and characteristics of your data dictate the appropriate
statistical tests. In animal behavior experiments we often rely on exposure
of a subject to a visual, auditory, or social stimulus. The appropriate
design, samples size and controls are important, but difficult, to consider.
