In the context of bacterial populations on a medium with varying composition, what term describes the process where a variant population outgrows others and becomes a new species?
Speciation
Test your knowledge on genetic drift, gene flow, founder effect, and allele frequency changes in populations. Learn about how these factors can lead to the formation of new species over time.
