sentences:  DNA sequencing data reported in 2011 showed that the Philippine crocodile is, in part, paraphyletic with regard to the New Guinea crocodile, and that the latter may constitutes a population within the Philippine crocodile.Among their two samples for the New Guinea crocodile, one was part of the Philippine crocodile clade and the other was separate, estimated to have diverged 2.6–6.8 million years ago.Both samples were taken from captives (could potentially be misidentified or hybrids) and the result should therefore be treated with caution.
