Small stone tools known as microliths-were essential to the growth of our species thousands of years ago.

According to an article published in the PLUS One, of the microliths are seen in the company Hiển cave in the tropical rain forests of Sri Lanka to date to 45,000 years ago. Their existence in this location suggests a range from “a variety of ecological contexts,” and for their use in Homo sapiens, the researchers believe.

The island of Sri Lanka is seen as an important area to examine how hunter-gatherers adapted to in the past.

The discovery of these types of artifacts in this setting, it is of interest to you, according to the scientists, because it is the tools most commonly associated with the hunting of medium to large mammals in the grasslands.

“It’s interesting that our evidence also shows that the stone tools, the technology has not changed much during the long period of human habitation from up to 48 000 up to 4 000 years ago,” said Andrea Picin, of the Max Planck Institute for the Science of Human History, and is the co-author of the study, in a statement.

The researchers believe that this is an evidence that technological change takes place within these early inhabitants has been very successful over the course of thousands of years.

“While we believe that this is a small stone tools were used as part of a projectile, the technology, which we have found bone tools, on the same site, the residual analysis and the impact of fracture analysis is in progress,” said Michael Petraglia, co-corresponding author of the paper.

“Regardless of the outcome, these miniaturized tools of stone, place in Sri Lanka is in a central position in relation to the discussion of technological sophistication among our kind. We have, in essence, was discovered in the ‘Upper Palaeolithic’ of the forest,” Petraglia added.
