Innovation and cultural transmission in the American Paleolithic: Phylogenetic analysis of eastern Paleoindian projectile-point classes

  • by Michael J. O’Brien, Matthew T. Boulanger, Briggs Buchanan, Mark Collard, R. Lee Lyman and John Darwent

North American fluted projectile points are the quintessential temporally diagnostic artifacts, occurring over a relatively short time span, from ca. 13,300 calBP to ca. 11,900 calBP, commonly referred to as the Early Paleoindian period. Painting with a broad brush, points from the Plains and Southwest exhibit less diversity in shape than what is found in the East, especially for the later half of the Early Paleoindian period. It remains unclear how various fluted-point forms relate to each other and whether the continent-wide occurrence of the earliest fluted-point forms represents a single cultural expression, albeit with regional differences. We used phylogenetic analysis to evaluate fluted-point classes from the eastern United States. Preliminary results suggest that there is both temporal and spatial patterning of some classes and that much of the variation in form has to do with modifications to hafting elements. Although our analyses are presently at a coarse scale, it appears that different kinds of learning could contribute in part to regional differences in point shape” (read more/open access).

See the entire history of the world here.

I wrote this and the entire history of the world in news feed form because I really like history jokes. This entire thing is probably the piece of writing that I am most proud of. It is also the most stolen thing I’ve ever done. People are constantly ripping off chunks and posting them on other sites without any credit. One such site that I won’t link to because fuck them posted this portion a few days ago and it has gotten 1.5 million views on their site. Again, with no credit. As someone whose employment is based on the quantifiable success of her content, and as someone whose career is based on having people know that I wrote the thing they’re currently enjoying, this is infuriating. But the bigger issue with that particular site, and in contextless, creditless posting in general, is that many people commented on that post saying that they wanted to see more, but they had no means of finding out that there was, in fact, more.

Here. More. All of history. All of it. In Facebook. For you

I hadn’t seen the one for WWI yet.
