Web24 de mai. de 2024 · Speciation is the process of formation of a new genetically independent group of organisms, called species, through the course of evolution. The process of splitting of genetically homogenous population into two or more populations that undergo genetic differentiation and eventual reproductive isolation is called speciation. Webspeciation - the populations become extremely varied and successful interbreeding cannot happen anymore; New species can also arise as a result of isolation:
