6hREwakXmAo 0:04–1:22 — Andersen and in this podcast I'm going to talk about animal behavior. If you study animal behavior you're called an ethologist.
6hREwakXmAo 1:26–2:46 — up and threaten it, it will spit at you and try to intimidate you. And so basically if you get too close and mess with it too much, it'll turn upside down.
6hREwakXmAo 2:51–3:59 — And so they didn't need to evolve any kind of a better method. Humans don't show fixed action patterns.
6hREwakXmAo 4:04–5:19 — You're probably familiar with Pavlov and Pavlov's dogs. Basically what happens is you start to associate two stimuli or one stimuli with some effect.
6hREwakXmAo 5:23–6:39 — just put crow vending machine into YouTube you'll find it. What he did is he used trial and error learning to basically build a vending machine.
6hREwakXmAo 6:43–8:01 — have the same response to every stimuli. Next we move up to what's called observational learning. Observational learning is watching another organism.
EyyDq19Mi3A 0:00–1:00 — Behavior is action in response to a stimulus.
EyyDq19Mi3A 1:02–2:05 — But first, behavior is really just a product of a pair of factors: Morphology, or the physical structure of an animal and physiology, or the function of that morphology.
EyyDq19Mi3A 2:08–3:09 — But as natural selection hones these traits, it's really selecting their associated behaviors.
EyyDq19Mi3A 3:11–4:15 — The questions focus on how a behavior occurs, and why natural selection has favored this particular behavior.

字幕依据：Andersen and in this podcast I'm going to talk about animal behavior. If you study animal behavior you're called an ethologist. And so that's ethology which is the study of animal behavior. When you study animal behavior there's a wide continuum of behaviors. 6hREwakXmAo@0:04
字幕依据：up and threaten it, it will spit at you and try to intimidate you. And so basically if you get too close and mess with it too much, it'll turn upside down. It's tongue comes out and it starts to ooze like the smell of dead decaying flesh. 6hREwakXmAo@1:26
字幕依据：You're probably familiar with Pavlov and Pavlov's dogs. Basically what happens is you start to associate two stimuli or one stimuli with some effect. And so for example he would work with dogs where he would ring the bell then he would give them some meat powder. 6hREwakXmAo@4:04
字幕依据：just put crow vending machine into YouTube you'll find it. What he did is he used trial and error learning to basically build a vending machine. He'd put quarters around it and then teach the crows that if the put the quarters inside a slot then food would come out. 6hREwakXmAo@5:23
字幕依据：have the same response to every stimuli. Next we move up to what's called observational learning. Observational learning is watching another organism. And you can see how we're headed up that continuum towards learned behavior. 6hREwakXmAo@6:43
字幕依据：But as natural selection hones these traits, it's really selecting their associated behaviors. It's the USE of the trait, using wings and feathers to escape predators, or using a long neck to reach leaves, that provides the evolutionary advantage. EyyDq19Mi3A@2:08
字幕依据：The questions focus on how a behavior occurs, and why natural selection has favored this particular behavior. Determining how a behavior occurs actually involves two questions: One: what stimulus causes it? And two: what does the animal's body do in response to that stimulus? EyyDq19Mi3A@3:11
字幕依据：When he observed newly hatched ducklings and geese, he discovered that waterfowl in particular had no innate recognition of their mothers. In the case of graylag geese, he found the imprinting stimulus to be any nearby object moving away from the young! EyyDq19Mi3A@5:27
