What taxa has the least number of speciation events and how many speciation events are there in total (the whole tree)?
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…

- which statement is false? 1)In the context of the evolution of senescence, the aphorism "live fast and die young" means that organisms with a more risky behavior will have a shorter life span. 2)Allopatric speciation is a type of speciation process that takes place in different geographic locations.arrow_forwardIn what theory of speciation do new species emerge within the geographic range of their ancestors?arrow_forwardWhat is the significance of the process of speciation to change in population from generation to generation? Explain the meaning of the theory referred to as "survival of the fittest". Why are the concepts of adaptations, survival and extinction closely related?arrow_forward
- How is pseudoextinction related to gradual evolutionary change?arrow_forwardWhy are vestigial structures among organisms evidence for evolution? Give an example of another vestigial structure.arrow_forwardWhat are the important differences between the vicariant and founder-event modes of allopatric speciation?arrow_forward
- What do we mean by pleiotropy and how can mutations in a single gene have extensive pleiotropic effects what might be the significance of such pleiotropic effects for evolution? Geographic isolation and reproductive isolation can both lead to speciation geographic isolation and reproductive isolation can both lead to speciation true? State that glycolysis occurs in both anaerobic and aerobic respiration?arrow_forwardHow does one species diverge from another? (When do we call a group a new species—and how does that process happen?) Using anole lizards or another very specific example(s), compare and contrast microevolutionary processes with speciation. As you discuss speciation, be sure to compare and contrast sympatric speciation with allopatric speciation and say whether the example you’ve chosen is allopatric or sympatric.arrow_forwardcompare and contrast between the following a) allopatric speciation and sympatric speciation. b) autopolyploid speciation and allopolyploid speciation c) natural selection and sexual selectionarrow_forward
- What does Speciation and Divergency mean in Biology?arrow_forwardDoes sexual selection have the potential to accelerate speciation, please provide an example..arrow_forwardExplain the type of speciation (allopatric, parapatric, or sympatric) most likely to occur under each of the following conditions: A. A pregnant female rat is transported by an ocean liner to a new continent. B. A meadow containing several species of grasses is exposed to a pesticide that promotes nondisjunction. C. In a very large lake containing several species of fish, the water level gradually falls over the course of several years. Eventually, the large lake becomes subdivided into smaller lakes, some of which are connected by narrow streams.arrow_forward
