You can decode the genome, you can look back, you can link us all together by a mitochondrial DNA, but we can't get further than the last ancestor, the last visible cell that we could sequence or think back in history.
你可以解码基因组，你可以回溯往昔， 你可以将我们所有人借由一个线粒体DNA联系在一起， 但是你无法追溯到第一个生命始祖以前， 这是 我们能基因测序和追溯历史的最后一个细胞。
