What I like about this abstract is that it confirms my hypothesis that
linguistic studies of the IE or proto-IE variety, have shallow
time-depth; and hence, linguists (of the proto-IE variety) should
pause before pontificating about phonetics of ancients without
studying linguistic areas as in Sarasvati civilization with mleccha
speakers.

I don't really understand
why this irrelevant information
should confirm anything about PIE
and I must say that I disagree
with the very low datation of PIE
and therefore rejects the dogmatic idea
that Historical linguistics is contained
within a 6000 year limits.
I don't buy a single word of this.

Modern humans have been living in Island Southeast Asia (ISEA) for at
least 50,000 years. Largely because of the influence of linguistic
studies, however, which have a shallow time depth, the attention of
archaeologists and geneticists has usually been focused on the last
6000 years – in particular, on a proposed Neolithic dispersal from
China and Taiwan. Here we use complete mitochondrial DNA (mtDNA)
genome sequencing to spotlight some earlier processes that clearly had
a major role in the demographic history of the region but have
hitherto been unrecognised. We show that haplogroup E, an important
component of mtDNA diversity in the region, evolved in situ over the
last 35,000 years and expanded dramatically throughout ISEA around the
beginning of the Holocene, at the time when the ancient continent of
Sundaland was being broken up into the present-day archipelago by
rising sea levels. It reached Taiwan and Near Oceania more recently,
within the last 8000 years. This suggests that global warming and
sea-level rises at the end of the Ice Age, 15,000–7000 years ago, were
the main forces shaping modern human diversity in the region.
