Textbook Question
Chapter 22, Problem 14PIAT
PROCESS OF SCIENCE A team lead by evolutionary biologist Hopi Hoekstra set out to test the hypothesis that predators are an agent of natural selection on mouse color. They made 250 plasticine models of mice that were alike in every way except that half were painted white and half were painted brown. Suggest one advantage and one disadvantage of using model mice instead of real mice in this experiment.

Imagine your anthropology professor studies a primate that eats insects. The primate's favorite food is a type of ant. She asks if you are interested in helping her analyze the data. You, of course, say yes!
Your professor tells you more about the ants, the primates, and the habitat. Ant color is determined by one gene. There are two alleles for this color gene: the brown allele and the green allele. The primates eat the ants year-round, but your professor knows that the way they eat the ants differs between the rainy season and the dry season. During the rainy season, when there are green leaves on the trees, the primates eat the ants off the green leaves. During the dry season, when the trees lose their leaves, the primates eat the ants off the brown tree branches.
Your professor has collected data to investigate if the primate acts as a selective pressure on the ant population, possibly changing the allele frequencies over time.
How intelligent is domestic cat compare to domestic dog?
Why can’t cats be sane size of large dogs? If they did get that big is that because of evolution or domestic cats eat a lot of cat food to get huge as dogs from kitten
Consider Lamarck’s idea in a hypothetical situation. For example, you decided that when you have children, you want them to be big ang strong. You decided to go to the gym every day for a year. You did all your exercise routines diligently and you were able to develop really bulky and toned muscles because you believed that your kids would inherit your big impressive muscles. Do you think this would work? Justify your answer using the concepts you have learned from Genetics, as well as Darwin’s concept of evolution.

- EVOLUTION LINK Charles Darwin once said, It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change. Explain what he meant.arrow_forwardFigure 1.15 Example of error bars in a graph. This graph was adapted from the peacock butterfly research described in Section 1.5. The researchers recorded the number of times each butterfly flicked its wings in response to an attack by a bird. The squares represent average frequency of wing flicking for each sample set of butterflies. The error bars that extend above and below the dots indicate the range of valuesthe sampling error. Figure It Out: What was the fastest rate at which a butterfly with no spots or sound flicked its wings?arrow_forwardImagine you are a scientist observing rats in the wild. As the rats reproduce, rats born with white fur slowly begin to outnumber rats with black fur. In three to five sentences, provide two or more different explanations of why the rats with white fur might be outnumbering the rats with black fur.arrow_forward
- Someone once said that if we could connect the auditory fibers coming from the cochlea (in the ear) to the visual cortex, and the visual fibers from the retina to the auditory cortex we would then see thunder and hear lightning. If this were the case what hypothesis would you use to explain these results?

List 5 things that make humans different from other apes and other species. Why did parallels between humans and apes make people angry?arrow_forwardEvolution by natural selection is founded on what basic idea? Random genetic mutations that help a species survive will be more likely to be passed to future generations. Only traits that will help an individual organism survive will be passed down to future generations. Only the biggest, strongest, fastest, or smartest creatures survive. Traits that animals acquire over their life will be taught to future generations.arrow_forward
