Question

E) Which of these can lead to speciation? (1 point)
Genetic drift
Natural selection
Reproductive isolation
All of the above

Answer 1

All of the above. Genetic drift, natural selection, and reproductive isolation can all lead to speciation. Genetic drift can lead to changes in allele frequencies in small populations, natural selection can drive adaptations that result in divergent evolutionary paths, and reproductive isolation prevents different species from interbreeding, allowing them to evolve independently.
