Chapter 3, Problem 5Q
A common creationist criticism of the finch study is, “But it’s just a little change in beak shape. Nothing really new has evolved.” Or put a different way, “It's just microevolution and not macroevolution.” The finch team continues to spend a great deal of effort on their project — traveling thousands of miles to the remote Galápagos every year, just to try to band an entire population of birds and all their nestlings and measure their bills. How would you respond to the creationists’ criticisms? Do you think the ongoing 30–year–effort of the finch bill project has been worthwhile? Is it useful to try to document microevolution, and does it tell us anything about how macroevolution might work?

Many creationists will allow that microevolution (for example,changing gene frequencies in a population) has occurred, and will even acknowledge that species adapt to different environments. However, they deny that macroevolution (they define it as the evolution of new “kinds”) is supported by evidence. Explain how they are mistaken. How might you help a creationist friend better grasp how modern scientists consider micro- versus macroevolution?
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 is probably the best explanation for the fact that Antarctic penguins cannot fly, although there is evidence that millions of years ago their ancestors could do so?
Group of answer choices
Penguins live on land and feed in the water; therefore they have no need to fly.
The Antarctic home of penguins is flat and barren; therefore there is no place to fly.
Ancestral penguins did not use their wings for long periods of time; therefore today’s penguins have only tiny, nonfunctional wings.
Ancestral penguins without large wings were better able to swim and feed in the water; therefore they passed their genes for shorter wings structure onto their offspring.

- 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? question 1 agree or disagree Differences among the four populations probably occurred when populations adapted to specific environments, because most evolution results in adaptation. question 2 agree or not Each population would probably have the same number of alleles—that is, versions of genes—than it…arrow_forwardGive a Darwinian explanation of how cheetahs evolved to become faster.

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.

- n which situation would it make sense to use the morphological species concept? When you are able to collect data about how individuals in your study use their habitat, but you are unable to determine if they interbreed When working with fossils from extinct organisms When you only have genetic data about each organism in your study When you are not able to collect data about how individuals in your study use their habitat, but you are able to collect reproductive dataarrow_forwardTopic: Galapagos Finches Darwin’s readings took him to a predictive theory of how species might change with time: what later thinkers have called microevolution. Darwin’s philosophical worldview then took him beyond his evidence to a conviction that environmental constraints could create whole new structures and organisms. Soon Darwin’s theory of macroevolution replaced the Creator with an environment that could create solely by constraint. For your thread: According to Chapter 13 section 13.1, define microevolution and macroevolution. The Galapagos islands have a great diversity of landscapes – from lush vegetation to nearly barren lava fields yet the Galapagos Finches survive on each island. How can this be explained? Using the varying bills of the Galapagos Finches in figure 13.3 and additional research, explain how microevolution is evidenced.arrow_forwardPeter and Rosemary Grant of Princeton University have studied the ecology and evolution of finches on the Galapagos Islands since the early 1970s. They have shown that finches with large bills (as measured by bill depth; see Figure) can eat both small seeds and large seeds, but finches with small bills can only eat small seeds. In 1977, a severe drought on the island of Daphne Major reduced seed production by plants. After the birds consumed whatever small seeds they found, only large seeds were still available. The resulting food shortage killed a majority of the medium ground finches (Geospizafortis) on Daphne Major; their population plummeted from 751 in 1976 to just 90 in 1978. The Grants research also documented a change in the distributions of bill depths in the birds from 1976 to 1978, as illustrated in the graphs to the right. In light of what you now know about the relationship between bill size and food size for these birds, interpret the change illustrated in the graph. What type of natural selection does this example illustrate? Source: P. R. Grant. 1986. Ecology and Evolution of Darwins Finches. Princeton University Press.arrow_forward
- What is the relationship between changes in gene frequencies and adaptations? The change in genes results in adaptations, which in turn, lead to the individual's ability to survive in its environment. The change in genes reduces adaptations, limiting the individual's ability to adapt for survival. The change in genes speeds up the process of adaptations, and the result is adaptations within any species will occur within a year. The change in genes results in adaptations in the individual, but these adaptations cannot be passed on to future generations.arrow_forwardIn comparative studies, it is important to be aware of relationships among species because a trait that appears in several closely related species is probably an adaptation it is not necessary to have large sample sizes if the species are closely related testing related species is more powerful than testing randomly chosen species experimental conclusions are statistically more powerful when data points are not independent of each other data points should be independent, and two related species might have derived their trait from a shared ancestor, rather than each having evolved it independentlyarrow_forwardIn the model shown below, discuss what kind of geographic barriers would have led to the finch speciation in the Galapagarrow_forward
- You are studying two variations of banana slugs. They have similar coloration and live in the same habitat. Although they are physically able to mate, there are no offspring that survive embryologic development. What can you conclude about the banana slugs? * Pre-zygotic barriers have forced them to be separate species. They are in Hardy-Weinberg equilibrium. Microevolution is occurring in both variations. They are two separate species. Two species of toads are reproductively isolated due to the fact that one species mates in early summer and one in late summer. Both species of toads evolved from a common ancestor. What type of speciation occurred?* OAllopatricarrow_forwardTry to outline a scenario explaining the evolution of the three species shown in panel g. Use migration, mutation, genetic drift, selection, reproductive isolation, gene flow, extinction, and many generations in your scenario. Based on your scenario, what are the components that are necessary in a population in order for it to split or diverge into two new daughter species from a single ancestor (the parent species)?arrow_forwardTwo biologists are arguing at a conference. One says that the Biological Species Concept (BSC) is superior. Her colleague argues that a different species concept is needed. Which of the following claims of the biologist are true and which are false? 1. The BSC potentially would work for all multicellular organisms. 2. A Morphological Species Concept would work better for cryptic species than the BSC. 3. If two populations of snails are separated by a huge distance, they cannot mate. This means the BSC cannot apply to them.arrow_forward
