- 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.arrow_forwardWhich of the following is an example of postzygotic reproductive isolation?a. Sperm of species A dies in the oviduct of species B before fertilization can take place.b. Hybrid zygotes between species A and B are spontaneously aborted early indevelopment.c.

A.) specialization on different food resources B.) specialization on different habitats C.) mutations that cause differences in pheromones D.) mutations that cause changes in ploidyarrow_forward
- 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…arrow_forwardEvolution is the theory that species change over time. According to this theory, new species form from existing species through variation and natural selection. The evolutionary process is very slow and the transformation of one species into another requires thousands of years. Several evidences are used to prove evolution and somehow reconstruct how this process occur: 1.Fossil Records. 2.Homologous Body Structures. 3.Vestigial structures. 4.Similarity of embryo. 5.Geographical evidencearrow_forwardYou 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_forward
