Human pressures lead to changes in the life history of organisms, with potentially huge consequences for fitness.
a) Fish harvesting can favor fish that reproduce earlier even if they produce fewer offspring. Suppose that a fish that reprodcues at age 3 years produces 20 eggs that will survive to adulthood, while one that reproduces at age 2 years produces only 5. If fish die after reproducing, which population will grow faster? One way to do this is to figure out which population would be larger after 6 years, which is two generations for those that reproduce every 3 years, and three generations for those that reproduce every 2 years.
b) Suppose half of the fish are harvested between ages 2 and 3 years. Which age of reproduction is now favored? what other effects do you think this would hvae on the population?
c) Compare this scenario to the effects of giving up migration. What information would you need to compute whether birds that spend the winter in cities will do better than those that continue to migrate?

Genentech, Inc., manufactured Protropin, a genetically engineered version of the human growth hormone. This drug’s purpose was to enhance the growth of short children. Protropin was an important product for Genentech, accounting for more than one-third of the company’s total revenue of $217 million. Although the drug was approved for the treatment of children whose bodies made inadequate quantities of growth hormone, many doctors prescribed it for children with normal amounts of growth hormone who simply happened to be short. There was no firm evidence that the drug actually increased growth for short children with normal growth hormone. Moreover, many people questioned whether it is appropriate to prescribe such a powerful drug for cosmetic reasons, especially when the drug might not work. Nor was there proof that it was safe over the long term. Was Genentech behaving ethically? Should it have discouraged doctors from prescribing the drug to normal, short children?

What Is Intelligence? This week’s lecture focused on the role of human intelligence. In your own words, what do you think intelligence is? Do you think intelligence is something you are born with or something that you can grow and develop? Why do you feel the way you do about that? How can engaging in good critical thinking impact your intelligence (or can it?) Your work should be at least 500 words, but mostly draw from your own personal experience. This should be written in first person and give examples from your life. Be sure if you are using information from the readings that you properly cite your readings in this, and in all assignments.
PLEASE NO PLAGIARISM!!!!!! PLEASE PUT IT IN YOUR OWN WORDS!!!!!!
