Since 2010, scientists in the United States have created the world's first "artificial life", the mycoplasma of prokaryotes, which caused a sensation. 8 years later, the research team dominated by the Qin heavy army completed the creation of a single - celled eukaryotic Saccharomyces cerevisiae natural 16 chromosomes artificially created as a single chromosome with complete function. The work shows that the natural complex life system can be simplified by manual intervention, the boundary of natural life can be broken by human beings, and it can even create a new life that does not exist in nature.
