An extract from "Genes, Cells and Brains" by Hilary & Steven Rose
As the geneticist and sequencer Eric Lander realised, the limits to what the HGP might reveal about human nature, either in general or specifically, have been strikingly exposed over the decade since the sequence was announced. Francis Collins found little of value from the list of risk factors he received when he sent his DNA samples to 23andMe. The paradigm that had framed genetics since the 1950s was beginning to fall apart. Unless set in the context of the development of the organism, DNA sequences were meaningless, and unless set in the context of evolution, the fact that humans and chimpanzees have nearly identical sequences was incomprehensible
