Textbook Question
Chapter 18, Problem 7QP
Perfect pitch is the ability to identify a note when it is sounded. In a study of this behavior, perfect pitch was found to predominate in females (24 out of 35 in one group). In one group of seven families, individuals in each family had perfect pitch. In two of those families, the affected individuals included a parent and a child. In another group of three families, three or more members (up to five) of each had perfect pitch, and in all three families, two generations were involved. Given this information, what, if any, conclusions can you draw about whether this behavioral trait might be genetic? How would you test your conclusion? What further evidence would be needed to confirm your conclusion?

You 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 experience
How much of our behavior is determined by our genes versus the environment? Provide two examples of why or why not.What do you think are the pros and cons for an individual if they believe genes determine their behaviors? What are the pros and cons for individuals if they believe nature determines their behaviors? What do you think are the implications for society if we put a lot of weight on nature or nurture?
Some insects, when attacked, will release a chemical that will cause other members of their species to become aggressive or fly. These chemicals are called

A scientist is researching behavior in a certain species of bird. The scientist realizes that by providing a certain stimulus only during a specific stage in early life will cause the baby birds to think he is their mother. This behavior by the baby birds is called
innate
imprinting.
fixed action behavior.
social learning

- Consider the following argument: Altruistic behavior in groups of related individuals is most likely driven by kin selection since related individuals would share DNA. Which of the following pieces of evidence would be most likely to weaken this argument? Data showing that only distantly related individuals are most likely to perform altruistic behaviors in order to protect each other Data showing that food gifts are given more common among family members than between unrelated individuals in a group Data showing that individuals that share a higher percentage of DNA in a group tend to show the most altruistic behavior between themselves Data showing that the more frequent an allele of a gene occurs in a population, the more likely that population performs altruistic behaviorsarrow_forwardWhich 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 abovearrow_forwardWhy imprinting is considered as a learned behavior and not an innate behavior?arrow_forward
