Abstract
Convergent evolution is a potent indicator of optimal design. We show here that convergent evolution occurs in genetic networks. Specifically, we show that multiple types of transcriptional regulation circuitry in Escherichia coli and the yeast Saccharomyces cerevisiae have evolved independently and not by duplication of one or a few ancestral circuits.
摘要
趋同进化是最优设计的有力指标。我们在此表明，趋同进化发生在基因网络中。具体而言，我们表明大肠杆菌和酿酒酵母中的多种转录调控电路是独立进化的，并非通过一个或几个祖先电路的复制。
