I was watching Nova last night, and the recovery of the 13,000 year old remains from the underwater cave in Mexico. as an aside, cave divers have to be the craziest/bravest people around. I get claustrophobic thinking about it. (link to article about same: https://www.scientificamerican.com/article/ancient-bones-reveal-girl-rsquo-s-tough-life-in-early-americas/ )
It struck me how there is so much inferred in these cases with so little evidence. You have to work with what you have, and in such cases you don’t have much. In science and especially in medicine, it is often stated a “series of one is series of none.” Meaning, of course, that you do not know if the one finding is an anomaly or is representative of a greater whole.
That said, it is fascinating to see what has been discovered, and to muse on what may be. Hopefully, further finds will surface and add to our understanding.
