Question

question 10 of 10
what is speciation?
a. the isolation of two parts of a population
b. the flow of genetic information between organisms
c. the formation of two or more species from a common ancestor
d. the radiation of adaptations through a species

Explanation:

Speciation is the process by which new species arise. It occurs when a single ancestral species diverges into two or more distinct species over time. Option A refers to a mechanism (isolation) that can contribute to speciation but is not the definition of speciation itself. Option B is about gene flow, which is related to genetic exchange within or between populations but not speciation. Option D is not the standard definition of speciation. The key concept of speciation is the formation of new species from a common ancestor, which is accurately described in Option C.

Answer:

C. The formation of two or more species from a common ancestor
