    Valencia as ancestor of Aphanius!

    No Orestias annoyingly, or Goodeids, or Anablepidae.
    I’d like to see more work done on this, look how far apart Epiplatys and Aplocheilus are! (I’d always assumed those were all part of an African/Asian radiation where the dessication of the ME, western Asia and eastern Africa had removed evidence apart from fossil taxa like Kenyaichthys)
    Rather messes with easy categories, Certainly the BKA and the AKA etc. must be having identity crises!

    Given this a thorough read now. Really interesting paper and throws up some nice questions, but agree with Pete re. the missing groups. Forgive the earlier post, Valencia is recovered as sister to Aphanius here.

    Looking over the tree again, I’d like to hear how this has been received within the field. The Fishbase team must be holding their heads and groaning if this is accepted. There are a number of obvious “eh?” situations.

    How do you feel about the use of aquarium strains in the analysis?

    If I understand it correctly, that term has only been used where provenance wasn’t available. Assuming due diligence was carried out for ID of those samples (and I doubt it would matter if the Xiphophorus had a bit of mixed blood, for example), I don’t see a problem with it, indeed I think it potentially shows good scientific use of aquarium collections.
