Speciation in the Butterfly

For example, the bird's nesting place is changed by the various trees available in the local environment. Geographical variation is mainly the result of adapting the species to the local environment, suggesting that genetic differentiation exists in a somewhat isolated population. As long as the gene flows through species within that range, this kind of genetic branching does not diverge species. Gene flux is likely to occur between individuals in the population of the area and between different local populations and is more likely to occur between adjacent populations than among isolated populations.

Biologists recognize two types of seed formation: heterogeneous and homogeneous species formation. Both have different geographical distribution of the population concerned. The formation of alien species is considered to be the most common form of speciation. It happens when the population is divided into two (or more) geographically isolated subdivisions and the creature can not bridge. Ultimately, the gene pools of the two populations changed independently, even if they were recombined, until they could not hybridize. In other words, they already pointed out

Biologists know little about the genetic mechanism of speciation. Several people believe that a series of small changes in each section will gradually lead to the formation of species. The founder effect can lay the foundation for comparatively rapid speciation, Genetic Revolution called by Ernst Meyer. Alan Templeton assumes that several important genes can be altered and given reproductive isolation. He called it genetic transformation. Lynn Margulis believes that most species development events are caused by changes in internal symbiosis. The number of creatures is very complicated. There may be formation of many species. Therefore, all the above ideas may be correct, but each situation is different. The book of Darwin is called "the origin of seeds", but even after 150 years the origin of the seed remains a mystery.

There are mainly two types of speciation. Isomorphic seeding means that more than one species evolves from ancestral species at the same time. The formation of alien species means the evolution of two or more species from ancestral species by geographical separation. The formation of alien species is when the ancestral gene pool is divided into two or more gene pools that are no longer tied by the gene flow. The resulting gene pools are separated from each other to create new species. With many generations, the new shapes become very unique and if they gather, or if they are the original parent group, they can not cross well.
