[Taxacom] Paraphyletic species: Crocodylus niloticus

[John Grehan]

It's not an example of transoceanic dispersal at all. That's just the
usual misrepresentation of molecular clock dates as actual or maximal.

The article did not give any indication of paraphyly. Please describe.

Dear All,      
       A recent paper indicates that Crocodylus niloticus is
paraphyletic with respect to the clade of Crocodylus species in the
Americas.  Not only a great example of a paraphyletic species, but also
transoceanic dispersal as well.  Link to news story is given below.
