" With modern technologies, there are plenty of other types of evidence for evolution. This involves similarities during the embryos of various species, exactly the same DNA sequences uncovered across all species, and an knowledge of how DNA mutations perform in microevolution.

Certainly they march on. That is certainly their business. These are the replicators and we are their survival devices. When Now we have served our purpose we're Solid apart. But genes are denizens of geological time: genes are forever.[83]
