Describe the two kinds of reproductive isolating mechanisms and explain their role in speciation.
a. What are the various types of reproductive isolating mechanisms that can lead to speciation?
b. What are the different modes of speciation?
c. Explain how evolution produce the tremendous amount of diversity among organisms.
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.

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_forwardCan speciation occur without complete physical separation of populations?arrow_forward
