Just a note on the paper on Pachyrhizus:
Separate Amazonian and Andean lineages = yes, but it’s P. ahipa than arose from P. tuberosus, not the opposite!

Sorry about that, but I read this from the abstract

The comparison of different evolutionary scenarios for the diversification history of yam beans in the Andes using approximate Bayesian computation suggests that Pachyrhizus ahipa and Pachyrhizus tuberosus share a progenitor-derivative relationship…

as meaning that P. ahipa was the progenitor and P. tuberosum the derivative.

Yep, you’re right, the species’ names should be in the reverse order. As it is it suggests that P. ahipa is the progenitor, but actually it’s the opposite.

Ok, good, I’m glad I didn’t have a senior moment :)
