Textbook Question
Chapter 15.4, Problem 1TC
To reduce the incidence of pesticide resistance, farmers are advised to place fields that are free of pesticides or pesticide-containing crops beside fields in which pesticides are used as usual. Given your understanding of how evolution works, explain how this method would slow the evolution of pesticide resistance in insects.

Give a Darwinian explanation of how cheetahs evolved to become faster. Your explanation is how natural selection works using Cheetahs as an example. Be sure to include and explain the ideas of differential reproductive success and descent with modification. (You do not need to mention the formation of new species.)
Why are fruit flies good subjects with which to observe the process of evolution through natural selection?
Fruit flies are good subjects because they have very long generations, and scientists can control their development over long periods of time.
Fruit flies are good subjects because they have short generations and scientists can control their development in the lab.
Fruit flies change into different species of flies each generation, so they have more features to study.
Fruit flies are K-strategists, and these are easier to study over short periods of time.
Observations of peppered moths living in seaside fishing villages compared to those
living near industrial cities demonstrated that:
evolution occurs so slowly that it is not possible to determine that it has happened in less than
a few hundred years
environmental changes can drive evolution of species
dark colored moths can out-compete light colored moths on trees with light colored trunks.
the environment near small cities tends to favor light colored moths

What type of evidence of evolution is this? *arrow_forwardThe fact that geneticists may be able to activate and inactivate genes in a chicken embryo to re-create a dinosaur is the most important to evolutionary scientists because: Question 18 options: This would help provide evidence on a genetic level that could prove the theory of evolution. Of all birds, we have the most complete genetic data compiled for chickens. Of all chordates, birds (like chickens) are the most like dinosaurs. This will help to prove the theory of punctuated equilibrium.arrow_forwardOne of Darwin’s finches, the medium ground finch (Geospiza fortis), is found on the small island of Daphne Major. These finches are seedeating birds. A major drought occurred on the island in 1977. Following the drought, the average beak size of medium ground finches had increased about 3%–4%. Why might a drought lead to an evolutionary change in beak size? Propose a hypothesis and explain how you could go about testing it.arrow_forward

- The two primates shown below both exhibit large eye orbits. One is a tarsier, the other is an owl monkey (the only nocturnal platyrrhine). Why do these primates share the trait for large eyes? Mark the best answer. Group of answer choices Random mutations, since having large eyes is abnormal in these species of primate. Convergent evolution, since both separately evolved large eyes to adapt to a nocturnal activity pattern. Both inherited this trait from their common ancestor, which was also nocturnal with large eyes. Unclear, cannot determine from the information given.arrow_forward. The images below show two separate theories of how organisms evolve. Which question below directly corresponds to whether Lamarck or Darwin are correct about their theories of the mechanisms of evolution? Why don’t the shorter neck giraffes feed on grasses and lower vegetation? How would the shorter necked giraffes in Lamarck’s theory survive to reproduce and pass on the “need” for longer necks if they were unable to reach food? Why won’t the taller necked giraffes in Darwin’s theory provide assistance to the shorter giraffes since they are the same species? Will the smaller giraffes be more adapted to hide from predators since they wouldn’t be visible from greater distances?arrow_forwardBirds and butterflies have wings they use for flying. The wings of butterflies are made of semitransparent, tough scales. Bird wings are covered with feathers. The wings of birds and butterflies did not evolve from a common ancestor that had wings. Instead, they have evolved as a result of similar environmental pressures. Which statement best explains the evolutionary relationship of birds and butterflies? Bird and butterfly wings are a result of divergent evolution because birds and butterflies did not evolve from a winged common ancestor. Bird and butterfly wings are a result of convergent evolution because birds and butterflies evolved from a winged common ancestor. Bird and butterfly wings are analogous structures because they have similar functions, are structurally different, and are a result of convergent evolution. Bird and butterfly wings are homologous structures because they have similar functions, are structurally the same, and are a result of divergent evolution.arrow_forward
- DDT is an insecticide that was used extensively in the mid-1900s to kill mosquitoes. It was very effective at first, but after a few decades DDT became less effective at killing mosquitoes because many populations had evolved resistance to DDT. Which of the following conditions would biologists say was required for the evolution of DDT resistance in a population? The mosquito population needed to evolve DDT resistance in order to avoid extinction. A few mosquitos were resistant to DDT before it was ever used. Exposure to DDT caused specific, nonrandom mutations for DDT resistance within the population. Mosquitoes in the population had learned to adapt to the high levels of DDT in the environment.arrow_forwardPeter and Rosemary Grant are two biologists that were able to document evolution happening among finches in the Galapagos Islands, over the course of about 35 years. What causes these species to change over time? Changing weather events, like droughts and floods caused different traits to be more or less beneficial. The islands they live on were shifting during that period of time. The humans living there killed the birds they didn't like., The predators in the area were more likely to eat large birds.
