Life sci 3c03 behavioural and evolutionary ecology - lecture 1 (intro) Darwin, natural selection, sexual selection: learning: How does an experience change your future behaviour (sometimes observable thus measurable, othe(cid:396) ti(cid:373)es it(cid:859)s (cid:374)ot it(cid:859)s late(cid:374)t i(cid:374)stead(cid:895) Two examples of learning are: pavlov and bf skinner. Skinner: how can you make an objective way of assessing behaviour to allow us to quantify/put number to that behaviour.

In science, you need objective way to measure behaviour so others can do that as well. Thus pavlov showed us the imp of neutral stimuli in the envt, and given the right pairing, this stimulus can be very imp from a biological perspective. Through his studies with dogs, he saw that a digestive response (production of saliva) occurs when a bell is heard in the envt.
