However, in terms of molecular evolution, its most important outcome was the characterization of repetitive sequences in the eukaryotic genome (Britten and Kohne 1968 ), a biological phenomenon that soon was incorporated in the non-darwinian theory of evolution of King and Jukes ( 1969 ), as well as in the idea of junk DNA (Ohno 1972 ). The history of molecular evolution starts in the early 20th century with "comparative biochemistry", but the field of molecular evolution came into its own in the 1960s and 1970s, following the rise of molecular biology.The advent of protein sequencing allowed molecular biologists [citation needed] to create phylogenies based on sequence comparison, and to use the differences between . The profession of "scientist" wasn't as established in the mid-19th century as it is today, but of course Darwin was a scientist, as he practiced what everyone would recognize as science.

Convergent evolution can produce similarities in body form Evolution in molecular systems is faster than organismic evolution by many orders of magnitude and thus enables researchers to observe optimization, adaptation, and other evolutionary phenomena on easily accessible time-scales, i.e. . It deals with the chemistry of life, and as such it draws on the techniques of analytical, organic, and physical chemistry, as well as those of physiologists concerned with the molecular basis of vital processes.
