The change in environement can lead to two selection diversification or convergence. Slide 6: vicariance: splitting of the geographic range of a taxon into discontimous parts by a biotic and abiotic barrier to dispersal. Slide 7: depeding on how the continent was certain organism were evolved. Slide 8: dispersal: parting reflecting the types of traits animalhas. As the contient move apart from each other,a land bridge were formed where the animal can move across the continents. Invasive species can disrupt evolution of other organism.
