Document Summary
Pnb 2xc3 chapter 3: hormones and neurobiology. Introduction: speaker saying robins have great visual acuity (va) asks 4 scientists to explain reason behind this, 1. Evolution: ns led to an increase in va as better vision lets robin forage and avoid predators: 2. Studying eye curvature shows why modern-day robins have better va than other birds: 3. Neuroscience: neural circuitry of vision explains better va: 4. Changes in robin vision at molecular genetic level: all are right. ^^ equally important to use both levels. Ultimate and proximate perspectives: levels of analysis problem: It is confusing when we ask a question in a specific level but get an answer from a diff. level: proximate level deals w/ immediate causation. Include questions like: how is it that, what is it that, sometimes defined as causes that are not evolutionary, ^^ bad definition because: Makes it seem like this level of analysis isn"t that important.
