Considering the shockingly global economy and social world we live in today, how is it possible that so many people seem to look the same? I walk around campus and see people who look just like people I have known before. And yet, these are entirely new people in a new community.
There are specific "looks" that seem to be repeated more often than others. Horsey faces, those kinds of mouths that don't naturally close; the upper lip is always raised and the teeth exposed. Chubby girls with receding chins also seem to pop up frequently. Often these "look" types are so similar from person to person that they could be siblings.
Yes, we are all descended from some common glop of sludge, but so much change and evolution has occurred since then I wonder why we aren't more varied. It makes sense in the years before easy travel because the farthest breeding partner was usually from a couple towns over.
Is the issue just that wide spans of travel have only become possible in what is really quite recent by the standards of humanity's time-line. There just hasn't been enough time to get a higher variety of appearances.
But why do a few specific "looks" appear so often, instead of us just all looking similar? Lots of people look quite unique, but there are three or four types that I always notice.
Additionally, what is the significance of the recent discovery that some of us have Neanderthal blood running in our veins? Are these people some of the ones that look so distinct and yet similar to many others in their own set? Are all the horse faced girls the ones with Neanderthal heritage?
