#Section 2: Evolution

Speciation in ancestor as following way

A- Non-swimming populations separated by a river may gradually diverge because there is no gene flow between them

B- Plants commonly exhibit polyploidy, meaning they contain three or more sets of chromosomes

C- The tendency for two species to diverge in morphology and thus resource use because of competition

Which of the following above condition allowed to which type of speciation?
