Degraded Planet

Living things do not actually evolve, but degenerate! Many documents mention creatures in ancient times, either with animal heads and human bodies, or dragons with nine sons, etc. This shows that there was no reproductive isolation between creatures at that time. Any creature can hybridize, making genes more diverse, and its lifespan can even reach thousands of years. This can explain the origin of biological diversity on the earth. However, as the populations of large numbers of species continue to expand, reproduction among similar species becomes more mainstream, and cross-species hybridization is no longer accepted. Those characters or creatures in ancient times have gradually become extinct, such as the strange creatures in the Classic of Mountains and Seas, the bird-headed men and lion-headed men in ancient Egyptian mythology, etc. Various genes will not evolve through new combinations, but will stagnate or even degenerate, such as reduced life span, reduced body size, etc. Physical changes on a cosmic scale (such as magnetic fields, radiation spectra, long-term periodic changes in cosmic ray flux) - affecting the molecular and genetic levels of life on earth. Organisms do not adapt passively but actively sense at the genetic level: they are able to recognize long-term trends in molecular reactions and thus adjust themselves. This adjustment leads to the progressive breakdown of reproductive isolation—genetic crossover between species becomes possible and boundaries blur. The phenomenon of cross-species reproduction has initially appeared, which is a natural, unintentional, and diversification process.
