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.)
Which of the following passages inaccurately describes the evolutionary process?
Wings are a highly valuable structure for any species as they increase survivorship and dispersal capabilities. Insect wings are hypothesized to have
evolved from dorsal extensions from their thorax that, over generations, were selected for as they helped to absorb solar energy, aiding in
thermoregulation. AS mutations continued to accrue, muscles attached to those flaps, making them more motile, and uitimately setting the
foundation for wingS.
Mammals have three ossicles, or tiny bones, in their middle ear that aid the hearing: the malleus, the incus, and the stapes. The stapes is the oldest
of the three bones, having evolved from the pharyngeal arch ll, called the hyoid arch. We know it's the oldest as it is found in tetrapods (the
columella) and in some more recently evolved fish. The malleus and incus evolved from bones of their ancestral mammal-like reptiles jaws, the
articular and the quadrate…
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.

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

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_forwardAnswer the following: This spectacular animal is a Lesser Bird of Paradise, Paradisea minor, from the highlands of Papua New Guinea. In the context of various evolutionary phenomena, why do you suppose: (a) This bird is confined to New Guinea and two nearby islands? Why would you not expect to find it in the mountains of Borneo? Explain in detail. (b) This spectacular tail presumably attracts predators; why hasn't natural selection acted to reduce it or camouflage it? Explain in detail.arrow_forward
- Humans in the 21st century use their thumbs extensively to operate touchscreens on cellphones. Imagine a scenario, where the human population evolves to have more dexterous thumbs over the next 300 years. Which of the following is a Lamarckian explanation for this evolutionary change (and, therefore, would an incorrect evolutionary mechanism?) humans that develop more dexterity in their thumb over their lifetime due to frequent use of cellphones pass that ability to their children humans that were born with a mutation for more dexterous thumbs have more children thumb dexterity is a dominant traitarrow_forwardIn several pairs of plant and animal species, plants have become modified such that only its animal partner can pollinate it, and the animals have become modified such that they are especially well adapted to pollinate just their plant partner.

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
- 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_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_forwardPesticides can be used to control a variety of pests, such as insects, weeds, rodents, bacteria, fungi, etc. Over time many pesticides have gradually lost their effectiveness because pests have developed resistance – a significant decrease in sensitivity to a pesticide, which reduces the field performance of these pesticides. 1. Why do pesticides lose their effectiveness over time? Use the theory of natural selection and evolution to explain.arrow_forward
