takes all sorts

A new article in Nature has made me question a long standing belief: people may be more different from each other genetically than we thought.

Human genome more variable than previously thought
Surprisingly large segments of DNA found to differ from person to person


It looks (just from reading the summary) that the variance may be due doubling and trebling of long sequences, which may be sequences of so-called 'junk' DNA. But I wonder whether 'junk' DNA will one day turn out to be important, and whether further investigation will reveal even more variance.

New things are discovered all the time. What interesting times we live in.
