A spider producing a web to ensnare prey, a beaver constructing a dam to engineer habitat, a bird fashioning a nest to protect their eggs, a crow using a stick as a tool to harvest insects, are all behavioral adaptations by which the motivations and neural circuitry underpinning these behaviors are genetically based, yet operational only through interactions with the external environment, as a mechanism to by which facilitate individual survival and reproduction. The web, the dam, the nest, and the tool are all examples of: Select one: O a. evolutionary trade-offs O b. signal displays O c. kin selection O d. extended phenotypes

Acorn woodpeckers (Melanerpes formicivorus) stash acornsin storage holes they drill in trees. When these woodpeckersbreed, the offspring from previous years often help withparental duties. Activities of these nonbreeding helpers includeincubating eggs and defending stashed acorns. Propose somequestions about the proximate and ultimate causation of thesebehaviors that a behavioral biologist could ask.
According to Hamilton’s rule,(A) natural selection does not favor altruistic behavior thatcauses the death of the altruist.(B) natural selection favors altruistic acts when the resultingbenefit to the recipient, corrected for relatedness, exceedsthe cost to the altruist.(C) natural selection is more likely to favor altruistic behaviorthat benefits an offspring than altruistic behavior thatbenefits a sibling.(D) the effects of kin selection are larger than the effects ofdirect natural selection on individuals.
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?
In general, animal behaviors arise from an interactionbetween the animal’s__________ and its_______. Some behaviors are performed correctly the first time an animal encounters the proper______ .Such behaviors are described as_________ .
Explain alarm calling in prairie dogs and ground squirrels. what are some data that indicatewhether alarm calling is selfish or altruistic behavior.? why altruistic behavior represents and evolutionary paradox. What is the primary hypothesis for themechanism that led to the evolution of alarm calling?
. WRITE ABOUT A THEME: INFORMATION Learning is definedas a change in behavior as a result of experience. In a shortessay (100–150 words), describe how heritable informationcontributes to the acquisition of learning, using some examplesfrom imprinting and associative learning

A Gelada baboon gives a warning cry that a predator is approaching so other members of its population could run away. This behavior is an example of innate behavior. survival of the fittest. altruistic behavior. dominant hierarchical behavior. imprinted behavior. A stickleback fish will attack a fish model as long as the model has red coloring. What term best applies to this behavior? Fixed Action Pattern habituation imprinting associative learning problem solving Which of the following is least related to the others? fighting over a mate territorial behavior Dominance heirarchy cognitive maps agonistic behavior
Which of the following is LEAST consistent with how behavior tends to evolve? Changes to underlying neural mechanisms, such as neurotransmitter receptors that affect motivation, can result in major changes in behavioral phenotypes Tweaks to the developmental process, such as play or learning, can cause evolutionary divergence in behavior Changes in the properties of sensory receptors can shift preferences and choices Variation in the gene for a given behavior results in population divergence Why are there biases in learning processes? The initial neural structure underlying learning may not allow every possible learned association Some cues are more likely than others to be associated with particular things, which has shaped the evolution of neural networks that represent the world Reducing the range of possible things a brain can learn can be one way to reduce the costs of learning All of the above
EVOLUTION CONNECTION We often explain our behaviorin terms of subjective feelings, motives, or reasons, butevolutionary explanations are based on reproductive fitness.Discuss the relationship between the two kinds of explanation.For instance, is an explanation for behavior such as “falling inlove” incompatible with an evolutionary explanation?

Cooperative behaviour is widely found among animals. Provide the following: 1) an example of cooperative behaviour between genetically related individuals 2) an example of cooperative behaviour between unrelated individuals. For each of the examples, also describe the mechanism(s) involved in maintaining cooperative behaviours during their interactions.
