Y-DNA Haplogroup T-M184 is found among the later Middle Pre-Pottery Neolithic B (MPPNB) inhabitants from 'Ain Ghazal, but was not found among the early and middle MPPNB populations.
As was previously found in the early Neolithic settlement from Karsdorf (Germany) a subclade of mtDNA R0 was found with Y-DNA T at 'Ain Ghazal.
