Here, the team of researchers examined microliths
small stone arrowheads/barbs used in hunting, to see how their design and usage by Mesolithic hunter-gatherers shifted in conjunction with climatic and environmental changes.
Prof Stoneking in an interview said: 'We have a pretty clear signal from looking at a large number of genetic markers from all across the genome that there was contact between India and Australia somewhere around 4,000 to 5,000 years ago.' Amazingly, the appearance of Australian dingoes and microliths
(or fine tools) appear in Australia in this time period, and that the dingo is almost similar genetically to the Indian wolf - our 'janglee' dogs.
The stone is chert, a flint-like substance used to chip small razor sharp blades off (microliths
) which were used by our ancient ancestors to build composite tools to hunt with.
In Stratum III, the 'international style' Beaker appeared, decorated with geometric horizontal bands, together with non-decorated, polished, slim sherds, a small copper dagger, a rectangular wrist guard and six half-moon-shaped microliths
. In Stratum II, a noticeably small copper dagger was recovered, probably for ritual purposes, along with one arrowhead, three rectangular wrist guards and ten obsidian microliths
in half-moon shape.

Along with this many cysts contain eosinophilic bodies with concentric and radial patterns that resemble spheroliths and microliths
that have been reported in 6 cases [3, 5, 12].

PAM is characterized by intra-alveolar deposition of calcium phosphates in both lungs in form of microliths

Later tools included Aurignacian blades (bottom right) and smaller implements called microliths
