Large genomic differences explain our little quirks
When the finished sequence of the human genome was unveiled last year, biologists said that it told a story of harmony for the human family. Every one of us, it turns out, shares 99% of our DNA with all the other people on Earth. But it's our differences that really fascinate us. And at last week's annual genome meeting in Cold Spring Harbor, New York, scientists revealed a wealth of data indicating a surprising conclusion about human diversity — much of it might be explained by large structural differences between individual genomes, not by tiny differences in individual genes.
