New Theory of Species Evolution

All animals, both in the fossil and extant, can be arranged into fan-shaped spectrum in every taxon according to their similarity of characteristics. The species are primitive at the two ends and advanced at the middle. The primitive two species resemble two types of more primitive species that can be confirmed as their ancestors respectively. The middle species is half similar to the two ancestors respectively. Therefore, a new evolutionary theory of crossbreeding speciation have been discovered. The special merits include: (1) A new evolutionary theory for replacing Darwinism. (2) The more advanced species came from two primitive species by crossbreeding and gene recombination. (3) Any species have two different ancestors, but not one common ancestor. (4) Almost all evolutionary relationships of ancestor-descendants of animals have been reconstructed. (5) Re-arranging the taxon of animals into regularly fan-shaped spectrums than the phylogenic tree. (6) The evolution steps consist of spectrums in nets, but not a evolutionary tree. (7) The crossbreeding always occurred by sexual pressure when mass extinction happened, accompanying explosion of new species.
