Acorn woodpeckers (Melanerpes formicivorus) slash acorns in storage holes they drill in trees. When these woodpeckers breed the offspring from previous years often help with parental duties. Activities of these nonbreeding helpers include intubating eggs and defending stashed acorns. Propose some questions about the proximate and ultimate causation of these behaviors that a behavioral biologist could ask.

Evolution connection we often explain our behavior in terms of subjective feelings, motives, or reasons, but evolutionary explanations are based on reproductive fitness. what is the relationship between the two kinds of explanation? for instance, is a human explanation for behavior, such as “falling in love,” incompatible with an evolutionary explanation?
In 1993, primatologist Richard Wrangham proposed that "Bonobo hypersexuality appears closely linked to the evolution of female-female alliances. I suggest that these alliances were made possible by relaxed feeding competition." Generate a hypothesis about why Bonobos behave this way.

- Ecology regarding sexual selection: In zebra finch females prefer males who have a larger yellow cheek patch. Researchers investigating this preference think that females must benefit from choosing males with large cheek patches. Provide three hypotheses regarding the direct, or indirect benefits, she might receive.arrow_forwardEgg-retrieval behavior of greylag geese is an excellent example of a highly predictable behavior. Interpret this behavior within the frame-work of classical ethology, using these terms: releaser, sign stimulus, and stereotyped behavior. Interpret the territorial defense behavior of male three-spined sticklebacks in the same context.arrow_forwardAnimals have evolved a range of strategies to successfully respond to threats and challenges. One of these strategies is the ability to learn. As we discussed, not every animal can learn and there are clear costs and benefits to this strategy. Suggest one benefit of the ability to learn and one potential cost. Briefly explain each. (1-2 sentences for each) Since learning is not universal, under which circumstances would it be most likely be a successful strategy? We discussed a framework that examines the influence of predictability on the success of learning ability. Describe this framework. Make sure you discuss all the available conditions and clearly state under which we would expect learning to be successful and where we would not expect it to be successful. What would be an alternative strategy to regulate behaviour when learning is not suitable? Briefly explain your choice. (2-3 sentences)arrow_forward
- Please your case for a specific example of altruism in the animal kingdom. Be sure to indicate which species are involved and describe the situation that makes your case. You can alternately state your case for why altruism does not exist in the Animal kingdom, but you will need to defend your stance with organismal examples.arrow_forwardA higher selection index value ALWAYS results to better animal performance. Is this true or not? Why or why not?arrow_forwardIn the initial encounter with the male intruder, resident male Cray fish showed extreme aggressive behaviors towards the intruder but after getting injected with octopamine, the resident male showed less aggression towards intruder males compared to their initial encounter. Based on what you know about serotonin an octopamine function, does the above situation of the injection octopamine makes sense? What might explain this and why do you say so? Also, what fitness benefits might a crayfish that shows dominance behaviors and a crayfish that shows subordinate behaviors gain?arrow_forward
- The idea that behavior must be either innate or learned has been called a “nature versus nurture” controversy. What reasons are there for believing that such a strict dichotomy does not exist?arrow_forwardYou were given two examples of learning in class. One related to wasps using landmarks to find nesting sites. The other related to mate choice in birds where the females were exposed to potential mates with artificial crests on their heads. What is the difference in the learning between the two studies? Group of answer choices the wasp study looked at the relatedness among individuals doing the learning both studies demonstrated that the behavior was purely genetic with no learning involved the bird study studied learning and development, permanent changes in behavior as a result of juvenile experience the wasp study studied learning and development, permanent changes in behavior as a result of juvenile experiencearrow_forwardEvolutionary biology What are 4 conditions in which natural selection favors altruistic behaviors in which the individual performs costly actions to benefit others?arrow_forward
