New archaeological analysis from The Australian Nationwide College (ANU) has discovered that Homo erectus, an extinct species of primitive people, went extinct partly as a result of they have been ‘lazy’.

An archaeological excavation of historical human populations within the Arabian Peninsula throughout the Early Stone Age, discovered that Homo erectus used ‘least-effort methods’ for instrument making and gathering sources.

This ‘laziness’ paired with an incapability to adapt to a altering local weather seemingly performed a job within the species going extinct, in line with lead researcher Dr Ceri Shipton of the ANU Faculty of Tradition, Historical past and Language.

“They actually do not appear to have been pushing themselves,” Dr Shipton mentioned.

“I do not get the sense they have been explorers wanting over the horizon. They did not have that very same sense of surprise that we’ve.”

Dr Shipton mentioned this was evident in the best way the species made their stone instruments and picked up sources.

“To make their stone instruments they might use no matter rocks they may discover mendacity round their camp, which have been principally of comparatively low high quality to what later stone instrument makers used,” he mentioned.

“On the web site we checked out there was an enormous rocky outcrop of high quality stone only a brief distance away up a small hill.

“However relatively than stroll up the hill they might simply use no matter bits had rolled down and have been mendacity on the backside.

“Once we seemed on the rocky outcrop there have been no indicators of any exercise, no artefacts and no quarrying of the stone.

“They knew it was there, however as a result of that they had sufficient sufficient sources they appear to have thought, ‘why hassle?'”.

That is in distinction to the stone instrument makers of later intervals, together with early Homo sapiens and Neanderthals, who have been climbing mountains to search out good high quality stone and transporting it over lengthy distances.

Dr Shipton mentioned a failure to progress technologically, as their surroundings dried out right into a desert, additionally contributed to the inhabitants’s demise.

“Not solely have been they lazy, however they have been additionally very conservative,” Dr Shipton mentioned.

“The sediment samples confirmed the surroundings round them was altering, however they have been doing the very same issues with their instruments.

“There was no development in any respect, and their instruments are by no means very removed from these now dry river beds. I believe ultimately the surroundings simply obtained too dry for them.”

The excavation and survey work was undertaken in 2014 on the web site of Saffaqah close to Dawadmi in central Saudi Arabia.

The analysis has been printed in a paper for the PLoS One scientific journal.
