In his book, Systematic and the Origin of Species, elaborated on Charles Darwin’s postulation that multiple species could evolve from a single common ancestor which created the species problem.

Ernst Mayr stated that “when populations within a species become isolated by geography, feeding strategy, mate choice, among others, it can result in them behaving differently from other populations through genetic drift and natural selection. He published more than 200 papers in several journals and 25 books, 14 of which were published after age 65.

Biological species concept -> The definition of a species as a population or group of populations whose members have the potential in nature to interbreed and produce fertile offspring (also called a sexual species) Distinguish between prezygotic and postzygotic isolating factors. Thi can lead in their evolving into new species. While there, Ernst Mayr accompanied the White South Seas Expedition to the Solomon Islands. en Mayr, on the basis of an understanding of genes and direct observations of evolutionary processes from field research, introduced the biological species concept, which defined a species as a group of interbreeding or potentially interbreeding populations that are … Ernst Mayr noted that. Therefore, people like Dawkins in England who still think the gene is the target of selection are evidently wrong”. Ernst Mayr played a central role in the establishment of the general concept of species as metapopulation lineages, and he is the author of one of the most popular of the numerous alternative definitions of the species category. Many members of the public believe that it is accepted broadly among scientists that races are not biological, only cultural, and the belief that races are biological is now just a thing of the scientific past.

A: Mitosis is the process of division of a cell into two daughter cells. Ernst Mayr defined a biological species as a population whosemembers can exchange genetic material during reproduction (seechapter 14). “The idea that a few people have about the gene being the target of selection is completely impractical; a gene is never visible to natural selection, and in the genotype, it is always in the context of other genes, and the interaction with those other genes make a particular gene either more favorable or less favorable.
