craig venter 和他的合作者人工合成了一个可以复制的细菌

马上有人批评他"PLAY GOD"

呵呵，这个肯定拦不住，能做的，肯定会有人做。技术是中性的，其利弊取决于人心及其欲望。

Craig Venter 多年来似乎一直是争议人物。。。
不过那个 Jim Collins说得对，他目前这个工作，很难说得上是创造新生命，而只是类似器官移植手术而已。

We report the design, synthesis, and assembly of the 1.08-Mbp Mycoplasma mycoides JCVI-syn1.0 genome starting from digitized genome sequence information and its transplantation into a Mycoplasma capricolum recipient cell to create new Mycoplasma mycoides cells that are controlled only by the synthetic chromosome. The only DNA in the cells is the designed synthetic DNA sequence, including "watermark" sequences and other designed gene deletions and polymorphisms, and mutations acquired during the building process. The new cells have expected phenotypic properties and are capable of continuous self-replication.

不过，这个方向发展下去，基因武器必然会出现。
