Why is a species called a qualitative stage of evolution, and a population – a unit of evolution?

With the formation of a new species, microevolutionary processes do not stop, but continue further without any interruption. With the emergence of a new species, only one stage of the grandiose and constantly ongoing process of evolution in the living world is completed and a new stage begins – the formation of a new species with new properties and a new fate. Therefore, a species is called a qualitative ethane of the evolutionary process, and since microevolution and speciation occur in populations of a species, the population is called the basic elementary unit of evolution.

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.
