MNOPS: M and S Survivors of a Papau New Guinea Bottleneck?

[elghund]

How could the sparesly populated and remote area in and around Papua New Guinea keep two really old haplogroups, M and S, whereas the rest of Asia and Europe had major replacements on larger landscapes: haplogroups NO for Asia and IJK for the Middle East and Europe. Is there a MS superclade before it goes back to MNOPS? If this is so, then that would suggest the haplogroups M and S were born there. If they were brought there, why are these two branches going all the way to the roots of MNOPS the only ones found in Indonesia and hardly anywhere else today?

M and S separated from K not too far from Central Asia; from here these haplogroups traveled towards Southeast Asia ending up on Indonesia and later Papua New Guinea.

Commenting to bump this thread, as these haplogroups are interesting and rarely spoken about.
