MCAT Question of the Day
    •

    Q:

    		 Anagenesis is a type of rapid evolution where a dramatic transformation occurs in the ancestral form, but no new species is formed. In fact, the ancestor species can be considered extinct, as it is therefore superseded by the new species it morphs into. This transformation is in contrast with cladogenesis, which is an evolutionary branching speciation where a parent species splits into two distinct species (this can occur when a few organisms end up in new, distant area). Which of the following is NOT an example of an anagenetic process?

    		 

    A

    		 Gene flow

    B

    		 Genetic drift

    C

    		 Natural selection

    D

    		 Sexual reproduction
