Whole Species Evolution

A UFO visited the earth secretly. There were two alien scientists on board the spacecraft. They saw that the biological evolution of the earth was slow, so they set off an evolutionary frenzy on the earth! They first conducted experiments on various animals and plants. Human evolution was relatively advanced, so they did not conduct experiments on humans. However, by chance... The male protagonist received the evolutionary hormone from the alien experiment and became the only super-evolved human being. (Actually, no, another alien scientist also conducted experiments on some humans because of his infatuation with human women. The woman was the lover of an ambitious man.) But this experiment was quickly terminated. They underestimated the power of evolutionary hormones. The speed of biological evolution was no longer under their control. The experimental subjects escaped back to nature. Since then, the earth has ushered in an era of evolution of all species.
