>>How does morphological evidence places Death Adders in Elapidae?

>>How do you know genetics evidence will place Death Adders in Elapidae if you do not compare it with anything else but Elapidae?





As per the analogy in the previous post. If Acanthophis were anything other than an elapid, that would pretty rapidly become obvious in phylogenetic analyses, as Acanthophis would then obstinately fail to group within the elapids. It's not exactly a subtle nuance.
