Question

explain how speciation helps in evolution​

Answer 1

Speciation. Speciation is theevolutionary process by which populations evolve to become distinctspecies. ... New species can also be created through hybridisation followed, if the hybrid is favoured by natural selection, by reproductive isolation

Answer 2

These same evolutionary changes can also result in the populations evolving into separate species. ... More specifically, ecological speciation is defined as the process by which barriers to gene flow evolve between populations as a result of ecologically-based divergent selection between environments.
