12. Dr. Kitty
Hauke is studying lobsters in Maine. She
noticed that over several years the average length of pincers had increased
within this population. She hypothesized
that having larger pincers provided a fitness advantage. To test her hypothesis, she introduced 75

that was similar to the lobsters’ natural sea environment. Over 10 years, Dr. Hauke observed this
isolated population of lobsters. What

were fewer small pincer lobsters mating during mating season.
large pincer lobsters could be found mating during mating season.

following is a picture of a Tomato Hornworm, which is the caterpillar stage of
the five-spotted hawkmoth (Manduca quinquemaculata). The white objects
protruding from the caterpillar are wasp eggs. The wasps lay their eggs on the

and the Tomato hornworms?
