The Nassau grouper is popular in Asia where restaurant goers can pick the grouper they want steamed for dinner from a selection of live fish swimming in tanks. Adult groupers can grow to large sizes (up to 3 feet long and 55 pounds), but those favored by restaurants are plate- sized juvenile and young adult fish. How would you expect the removal of these younger, smaller fish to affect the life history evolution of the remaining population? How might life history parameters such as age and size at reproduction and investment in growth versus reproduction evolve in response to fishing pressures?

One way to prevent a small population of a plant or animal species from going extinct is to deliberately introduce some individuals from a large population of the same species into the smaller population. In terms of the evolutionary mechanisms discussed in this chapter, what are the potential beneﬁts and drawbacks of transferring individuals from one population to another? Do you think biologists and concerned citizens should take such actions?
The Amish community in Eastern Pennsylvania stemmed from a small closed population of around 200 individuals from Eastern Europe. Certain mutant alleles have been found at higher frequencies in the Amish relative to the general population, including a rare form of dwarfism called Ellis-Van Creveld syndrome, in which the short stature is accompanied by polydactyly. Evaluate the factors driving evolution in the Amish population. Is this form of evolution adaptive? Explain.
While the French biologist LaMarck was correct in proposing that evolution does occur, he believed that the long necks of giraffes evolved as generations of giraffes reached for ever higher leaves on the trees. Using these observations, LaMarck proposed the theory that evolution occurs due to the inheritance of characteristics acquired during an organism’s lifetime. From what you know about the scientific method, why is this incorrect?
Which of the following evidence is not consistent with the idea that evolution is responsible for the diversity of animals we see today? A. The presence of vestigial organs in extant species B. Structural homologies among very different animals C. Fossil records of intermediate life forms D. Earth is not the center of the galaxy or universe Which of the following is not a part of the allopatric speciation by natural selection model? A. Geographically isolated populations evolve or change in response to novel environments. B. Reproductive isolation evolves as a by-product of changes in other traits associated with adapting to new resources or environments. C. Selection against hybridization leads to exaggeration of signals to facilitate recognizing conspecifics( individuals of the same species). D. Changes among or between populations occur while populations are geographically separated. Which of the following is not an example of the evolution of a key innovation (anew trait)…
Anole lizards can be found on many islands in the Caribbean that share similar environmental habitats. Anoles on the different islands share similar ecological morphotypes because of their similar habitats. Anoles on each island have evolved from a common ancestor into a variety of different species that occupy different ecological niches as shown below. Which of the following statements explains how the morphotypes found on one island, and shown in the figure, occurred as a result of speciation? A - Convergent evolution occurred, causing new species to evolve based on diverse new habitats. B - Phenotypic diversification occurred as a result of divergent evolution as the anoles adapted to new habitats. C - Natural selection occurred, so individual anoles with certain phenotypes can survive and reproduce only in a specific ecological niche. D - Reproductive isolation occurred as a result of habitat isolation since the anoles are unable to move into different ecological niches to breed.
The upper forelimbs of humans and bats have fairly similar skeletal structures, whereas the corresponding bones in whales have very different shapes and proportions. However, genetic data suggest that all three kinds of organisms diverged from a common ancestor at about the same time. Which of the following is the most likely explanation for these data? Group of answer choices Forelimb evolution was adaptive in people and bats, but not in whales. Natural selection in an aquatic environment resulted in significant changes to whale forelimb anatomy. Humans and bats evolved by natural selection, and whales evolved by Lamarckian mechanisms. Genes mutate faster in whales than in humans or bats.
How were researchers able to determine that Soapberry bug mouthparts had evolved to be shorter in some populations? By growing a population in a laboratory and forcing them to eat smaller walled fruits for several generations By analyzing the gene variants for mouth parts in different populations By experimentally introducing new fruits into the the ecosystems that the populations they suspected were evolving live in By comparing the mouthparts of modern populations to museum specimens collected in the past
Assume that a lineage of rainbow trout accumulates mutations over time that make the trout a uniform dark brown with orange spots and produce a dorsal fin shape that is very different from all other rainbow trouts. This group of rainbow trouts also has lips that are twice the size of other rainbows and they have a much narrower body. How do we know when the natural selection of such characteristics results in a new species of fish?
What is the difference between micro- and macroevolution? a. Microevolution describes the evolution of small organisms, such as insects, while macroevolution describes the evolution of large organisms, like people and elephants. b. Microevolution describes the evolution of microscopic entities, such as molecules and proteins, while macroevolution describes the evolution of whole organisms. c. Microevolution describes the evolution of populations, while macroevolution describes the emergence of new species over long periods of time. d. Microevolution describes the evolution of organisms over their lifetimes, while macroevolution describes the evolution of organisms over multiple generations.
It has taken millions of years for the ancestors of whales to change into what we know today, as indicated in the diagram below. Based on your knowledge of evolution, which of the following is a reasonable explanation of why the organisms in the diagram changed over 25 million years? Question options: As the environment changed the food sources became more difficult to obtain so characteristics that allowed the organisms to hunt in an aquatic environment became more advantageous. As the environment changed the temperature became too hot and the organisms began to move to a more aquatic environment to keep cool. As the environment changed the food sources became more difficult to obtain so the organisms decided to change their characteristics to ones that would be beneficial when hunting in an aquatic environment. As the environment changed the predators on land became better adapted to hunting the whales ancestors forcing them to live in more aquatic…
A population of 600 scorpions was split into four populations when irrigation canals were built through their habitat. The four new populations were called the Northern, Southern, Eastern, and Western populations. Each new population consisted of about 150 individuals. The four populations continued to evolve, and no migration occurred among populations. One hundred generations later, each population still has about 150 individuals, and a biologist investigates them. Consider what a biologist expect to see in the four populations after 100 generations if the environment did not change for any of the populations. Would the biologist agree or disagree with the following statements? a) In the smaller populations of 150 individuals, the processes leading to genetic drift could have a stronger influence on a gene than natural selection. agree or disagree b)Chance survival of some individuals occurred in some generations, but not every generation. agree or disagee c)Beneficial mutations…
. A population of red deer were trapped on an island off of England during the last interglacial period. Within 6,000 years, the population evolved from a mean weight of 200 kg toa mean weight of 36 kg. The generation time of red deer is 5 years and the narrow senseheritability of body weight is 0.5. What is the rate of evolutionary change (in Darwins)?
