[Taxacom] Richmond and Jungers on Orrorin?

[Richard Jensen]

And, that Richmond and Jungers didn't "group Orrorin with 
Australopiths". Their data, and their chosen method of analysis, did 
that. One might question the way they scored their OTUs, recorded and, 
perhaps, transformed, their data, and the methods chosen for their 
cluster analysis.
