Ace. Cindy is very curious about the formation of species. B) most new species accumulate their unique features relatively rapidly as they come into existence, then change little for the rest of their duration as a species. Only a few genetic changes are needed to spur the evolution of new species—even if the original populations are still in contact and exchanging genes. Moreover, self-pollinated plants rarely, show variations in characters. By O. F. COOK. sequence events that can lead to reproductive isolation of two populations.

D) speciation is usually due to a single mutation. That process is known as speciation that takes place in the course of evolution. describe factors that may lead to the development of new species: isolating mechanisms, genetic drift, founder effect, and migration. reproductive isolation. Darwin envisioned this process as a branching event and diagrammed the process in the only illustration in On the Origin of Species (Figure 18.11a).

Darwin envisioned this process as a branching event and diagrammed the process in the only illustration in On the Origin of Species (Figure 18.11a). Reproductive isolating mechanisms are the biological properties of individuals which prevent the interbreeding of naturally sympatric populations. B. Gene flow and competition ... After some generations these become continuous and gradual variations in the possessor would be so distinct that they form a new species. Answer: The factors involved in the formation of new species are. Another important factor may be the presence of humus-rich organic soils (low temperatures and constant humidity), typical of mountain areas, which promote the growth of land species.
