Frog - You must have missed (or selectively filtered out) the extended and very excellent discussion on Telemeres on this and the RB board...Telemeres are the ends of each gene which indicate "age" and are quite defineable by DNA tests...
Add this to eye color, hair color, skin pigmentation, and the possibility of determining "cranialfacial traits," etc., and you have an amazing description of a particular human at a particular time in history.
DNAP sure feels on the right track and is soooo far ahead of others.
OT - Frog - I'm never sure why you stick around a stock you seem to be so down on, but some day I'd really like to hear about a company (or even something in your life) that you are truly excited about... I know you have it in you....
God Bless and take care,
Robert
