Any species has two different ancestors, but not one-common ancestor as in Darwinism. The new evolutionary theory is described as the more advanced species came from two primitive species by crossbreeding and gene recombination, which is supported by species spectrum and polyploidy. In the fossil and extant organisms, any advanced organism always possesses characteristics combined from two primitive ancestors. The characteristics of species in every taxon constitute a fan-shaped spectrum, in which the left primitive type is obviously come from one ancestor, the right from another ancestor, and the middle is half similar to the both ancestors respectively. Therefore, the simple and convenient way of the combination of characteristics from the two ancestors is crossbreeding. All plants with haploid, diploid, or polyploidy can reproduce successfully in despite of the paired chromosomes. Paleopolyploidy is the result of genome duplications and widely exist in the plants and animals, which always originated from crossbreeding. The crossbreeding of plants occurred all the time.

Firstly, I discovered a linear loop system hidden along skin, which is the foundation of integrative physiology for horizontal regulation of body function. Secondly, I discovered a new evolutionary theory of crossbreeding as in this book. Now, I am working at a third step: structure, function and evolution of soul, which make theology scientific.
