Why do species definition matter in conversation biologyarrow_forwardOriginally, the main task of taxonomists was to discover new species and give them unique names. In a natural system of classification, they must also figure out the evolutionary relationships of the species they discover. Which do you think is more difficult: the original task or the modern one? Describe some of the reasons why it is more difficult.arrow_forward

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…arrow_forwardIf 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.arrow_forward
- The biological species concept defines a species by its morphology. In other words all members of the same species look alike? True or false?arrow_forwardWhen constructing phylogenetic trees, what is the purpose of applying maximum parsimony? Parsimony allows the researcher to "root" the tree. For trees based on morphology, the most parsimonious tree requires the maximum evolutionary events. The outgroup roots the tree, allowing the principle of parsimony to be applied. For trees based on morphology, the most parsimonious is the one that uses the simplest explanation of evolutionary events.arrow_forwardWhat is evolutionary history of a species called?arrow_forward
