Science and the near perfect control.

The mechanisms of science involve the use of controls. The near-perfect control is the identical twin brother of Scott Kelly. Scott just returned from a medical mission on the International Space Station, where he endured for about 1-year.
Scott will be examined for any changes that occurred, while in space, as compared with his brother who remained on earth. Genetically identical individuals. Can't get a better control than that.
Welcome back Scott!

"Near perfect", but not perfect. Fifty years of epigenetic variation results in identical twins being not-so-identical genetically. That said, it is the best you can hope for, and is pretty good as a control for large effects.

Yes, indeed, as you say, identical twins are not absolutely identical. Epigenetics is an interesting/fascinating area of research."Near perfect", but not perfect.
