8)
What data would suggest that a species evolutionary history includes sexual selection as a mechanism that helped shape the species?
A)
If males and females are significantly different from each other (sexual dimporphism)
B)
If some males reproduce with multiple females while other males do not reproduce
C)
If males engage in "risky" behavior
D)
If males and females form different social groups (i.e. herds are formed from either males or females but not both)
2) A species is a group of individual organisms that interbreed and produce fertile, viable offspring. According to this definition, one species is distinguished from another when, in nature, it is not possible for matings between individuals from each species to produce fertile offspring. Evolution is an important mechanism in the formation of new species. The evolution of a new species requires several components including all, BUT
A) Evolution of a new species requires a long time.
B) Evolution of a new species requires the need for a genetic change.
C) Evolution of a new species requires a separation that prevents interbreeding.
D) Evolution of a new species requires mutations that produce new genetic traits.

- 2) A species is a group of individual organisms that interbreed and produce fertile, viable offspring. According to this definition, one species is distinguished from another when, in nature, it is not possible for matings between individuals from each species to produce fertile offspring. Evolution is an important mechanism in the formation of new species. The evolution of a new species requires several components including all, BUT A) Evolution of a new species requires a long time. B) Evolution of a new species requires the need for a genetic change. C) Evolution of a new species requires a separation that prevents interbreeding. D) Evolution of a new species requires mutations that produce new genetic traits. Not Gradedarrow_forwardMorphological differences are abundant among many species. We make assumptions about why adaptations exist, but to understand whether a specific trait is a adaptive and why, researchers must create experiments that have all the following, EXCEPT: a. replication of each treatment to ensure reliability of results. b. experimental design that enables all full interpretation of differences. c. include control groups. d. hypotheses that are testable and falsifiable. e. exceedingly small sample sizes in each treatment group.arrow_forwardThere are a number of evolutionary hypotheses that researchers have developed to better understand the high prevalence of complex diseases like type 2 diabetes and obesity across populations today. The best explanation for this high prevalence of complex diseases is: a. Neel's hypothesis b. Speakman's hypothesis c. Meyer’s gene hypothesis d. Thrifty gene hypothesis e. Drifty gene hypothesisarrow_forward
- Two parents, who are thought to be different species, mate and produce viable hybrid offspring. When two of these hybrids mate, their offspring are not viable. What is the BEST interpretation of this data? A. The original parents are the same species because they can breed together. B. The original parents are the same species because they can breed together and produce viable offspring. C. The original parents are not the same species because they produce hybrids that impair the species’ development or survival in its environment. D. The original parents are not the same species because they produce hybrids that can have reduced viability and fertility when they mate.arrow_forwardTrue or False a.) Evolution creates genetic variation in a population. b.) Fitness refers to an allele's ability to help the organism evade predators. c.) The process of natural selection may increase or decrease the frequency of a particular allele in the population depending on the environment. d.) A potato species acquires a mutation in its catalasegene that allows it to function in very cold environments. However, this catalaseis denatured at room temperature. This is a good example of fitness cost.arrow_forwardExplanation 2. Imagine you are a farmer researching the impact of GMFs. What is one advantage and one disadvantage that would be relevant to your work? Explain each. 3. What was the original purpose of Darwin's voyage on the H.M.S. Beagle, and what was the ultimate significance of the voyage? 4. Suggest two ways that a synthetic biologist can change the course of evolution. 5.

- What consequences does horizontal gene transfer pose for evolutionary biologists? a. It can pose difficulty in the reconstruction of phylogenetic trees, because it can obscure phylogenetic relationships. b. It can pose physiological problems in some organisms, making it very hard to study them. c. It can pose difficulty in breeding between different individuals of the same species. d. Because it is transfer of genes between the same species, it can make individuals look very more similar than they actually are. e. All of the above.arrow_forwardIn addition to evolution through vertical descent, evolutionary changes can also occur by horizontal gene transfer, and this process involves 1. mostly eukaryotic organisms. 2. competition 3. the transfer of genes from one organism to another one that is not its direct descendant and might even be from a different species. 4. a recent time in the history of life in our planet. 5. the transfer of genes from one organism to another one with a parent-offspring relationship.arrow_forward21) ALL BUT ONE of the statements below helps to describe gene flow. That is A) B) Without genetic variation, some of the basic mechanisms of evolutionary change cannot operate. There are three primary sources of genetic variation: 1. Mutations II. Gene flow III. Sexual reproduction D) It depends on a chance event that changes the gene pool. It can reduce the genetic differentiation between the two groups. It involves the movement of alleles from one population to another. It includes migration or the movement of individuals between populations. Some mutations always occur from generation to generation. But most mutations do not persist over time in the gene pool. Which mutation is MOST likely to become established and persist in a species?arrow_forward
- The biological species concept is based on the assumption that species are reproductively isolated and do not share genes. And yet a number of organisms that are considered different species hybridize (mate and exchange genes). Hybridization between different species is more common in plants than in animals. Propose some possible reasons for this difference.arrow_forwardevolutionary trade of is when a trait is at an advantage in a context a) explain how the evolution of the different shades of color is an example b) what evidence can you use to support this ideaarrow_forwardWhich of the following are INCORRECT about inbreeding? select all that apply a.) It speeds evolutionary change b.)It causes evolution c.)Allele frequency changes d.)Genotype frequency does not change e.)Heterozygosity decreasesarrow_forward
