Use an example to illustrate how two different species concepts can lead to different speciesdeterminations. In other words, describe two organisms which would be considered the same speciesby one concept, but a different species by another concept. Be specific about WHY eachdetermination would be different. You may not use the maggot fly example from the case study wediscussed.IQuestion 3 options:26109,754OCT 51829tvԸNAO2신

Explain the biological species concept. Why is it not a perfect definition of a species?
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.
Two 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.
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 isolation
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…
