What process underlies speciation?

Mutation process, recombination and pressure of mutations provide the emergence of new alleles in populations (as well as chromosomes and entire chromosome sets). The mutational process provides the emergence of new variants of the trait that underlies microevolution (speciation)

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
