摘要

The discovery of the structure of DNA, and the realization that the chemical basis of mutations is changes in the nucleotide sequence of the DNA, meant that the history of a piece of DNA could be traced by studying variation in its nucleotide sequence found in different individuals and in different species. But it was not until rapid and inexpensive methods became available for probing DNA sequence variation in many individuals that the efficient study of molecular evolution in general―and of human evolution in particular―became feasible. Thus, the development in the 1980s of techniques for efficiently scoring polymorphisms with restriction enzymes and amplifying DNA enabled the study of molecular evolution to become a truly booming enterprise. What follows is a personal and, by necessity, selective attempt to consider what the accelerating pace of exploration of human genetic variation over the past two decades has taught us about ourselves as a species, as well as some suggestions for what may be fruitful areas for future studies.
