Opening the human story with science!
There's more knowledge in this little girl's pinkie than some people have in their entire head! Your body is full of information: about your environment, about your daily routines and habits, and about your parents. Pains and scars tell about experiences---even if we're not sure just WHY we have a particular hurt, like my friend Rick and his mysterious ache in his side, which the doctor couldn't illuminate. So what is a 40,000 year old pinkie tip able to tell us about the human race---long before any written record? http://www.nytimes.com/2012/01/31/science/gains-in-dna-are-speeding-research-into-human-origins.html?_r=1&smid=fb-nytimes&WT.mc_id=SC-E-FB-SM-LIN-DTH-013112-NYT-NA&WT.mc_ev=click
