Call it Mycoplasma mycoides lite—researchers have established what is approximately a minimal organism by removing about have of the genes from theMycoplasma mycoidesgenome. The result is a set of 473 genes which, collectively, appear to be required for any kind of reasonable performance. That is an enormous level of complexity. Furthermore, about one third of that minimal gene set is of unknown function. As J. Craig Venter put it, “We’re showing how complex life is, even in the simplest of organisms. These findings are very humbling.” Read more
