Step by step
Solved in 2 steps
- 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 dataWhich of the following statements about sympatric speciation is correct? It is a process through which two populations can diverge and develop reproductive isolation while in two different geographic area. It is the most common mechanism for populations to form independent species. Postzygotic isolation is the main form of reproductive isolation for the sympatric speciation process. Genetic isolation through large scale chromosomal mutations, such as chromosome inversion or polyploidy, are more likely contributing to sympatric speciation. None of the aboveThe first step leading to allopatric speciation is (a) hybrid inviability (b) hybrid breakdown (c) adaptive radiation (d) geographic isolation (e) paedomorphosis
- There are a lot of pros and cons to using the biological concept. It is only one out of several types of concepts used to define a species. What would be the main criterion used for determining / differentiating between species? gene flow O niche differences O geographical isolationSpecies Concepts Review The Baltimore Orioles and Black-backed Orioles species complex has conflicting evidence in support of each being their own species and in support of them being the same species. Review the evidence below for each hypothesis, then, using that evidence, explain whether they should be classified as distinct or the same species based on each species concept. Then, using the overall evidence, decide whether to classify them as the same or different species. Genetic Information (In the Species Concepts lab, we used a "controversial" 10% cutoff. A more realistic cutoff might be 1%. Let's use a 1% cutoff for this activity.) Sequence Differences Baltimore Oriole vs Black- backed Oriole Cytochrome b 0.26% Control region 0.74% 2A. Based on the genetic information above, should the Baltimore Oriole and Black-backed Oriole be classified as one species or two species?In sympatric speciation (fill in the blank) can result in (fill in the blank) and lead to formation of new species from a population that (fill in the blank) fill in the blank with the following: is geographically isolated, gene flow, reproduction isolation, is in the same environment, genetic drift, or ecological isolation
- Which of the following statements is true regarding the phrase "adaptive radiation"? O It refers to multiple speciation events within an evolutionary lineage. It refers to many populations of the same species. It is the result of genetic drift occuring many times over evolutionary time. Gene flow is an evolutionary mechanism that can account for adaptive radiations.The biological species concept depends on the existence of barriers to reproduction. What are they? Does this species concept apply in all situations? Think of an example from nature where the biological species concept would NOT be that applicable. Which species concept would be better in this example? How does speciation occur? What environmental factors might contribute to speciation? Can an individual speciate? Use terminology for the two kinds of speciation we have learned about. What is “gene flow”? What does it mean if there is NO gene flow? Two groups of individuals are separated by either side of a canyon. One researcher found that they do not cross the canyon at any point. The group on the north side have fluffy tails and thicker coats, and they do not eat moss. The south side individuals eat moss almost exclusively, have a thin coat and tail, but otherwise are generally identical. When in the lab they mated successfully, and the offspring of that mating also mated…Bird guides once listed the Myrtle warbler and Audubon's warbler as distinct species, but applying the biological species concept, recent books show them as eastern and western forms of a single species, the yellow-rumped warbler. Experts must have found that the two kinds of warblers: Question 10 options: live in the same area. successfully interbreed in nature. look enough alike to be considered one species. are reproductively isolated from each other. are allopatric.
- If the phylogenetic species concept (PSC) were used to define species, rather than the biological species concept (BSC), how might that change the estimates of species diversity (numbers of species) on a worldwide basis? True or False: Estimates of species diversity are likely to change if the PSC is used. In particular, one would expect the number of species to increase. This is because individuals from divergent allopatric populations that can potentially interbreed would belong to the same species under the BSC. These same organisms would be classified as members of different species under the PSC.Please use and cite any source(s) you can find to answer the following questions:1. List and describe the different ways in which species are defined.2. Explain how each of the following makes it difficult to clearly define a species: variation within aspecies, geographically isolated populations, asexual species, fossil organisms.3. List and describe the pre-zygotic barriers as well as the post-zygotic barriers.4. Explain why allopatric speciation would be less likely on an island close to a mainland than on a moreisolated island.Make or create one question about Speciation and ecology (Nature of species, reproductiva isolation, genetic drift and natural selection, geography of speciation, adaptive radiation and biological diversity, the peace of evolution). Just one question about any of this topics.
