Homo erectus may have gone extinct because they were lazy, new research claims.

Scientists believe that the "least effort" strategies used to build tools and collect resources may have contributed to the fall of the primitive human species.

Unlike other hominids, the tools created by Homo erectus were comparatively low quality and were built using low quality materials that are nearby, experts say.

This contrasts with stone tools made by other hominid species, including early Homo sapiens and Neanderthals, who climbed mountains to find good quality stone and transported it over great distances.

This Laziness combined with the inability to adapt to a changing climate likely resulted in the extinction of the species, scientists say.

Researchers from the National University of Australia (ANU) studied the ancient populations that lived in the Arabian Peninsula during the Early Stone Age.

The team examined stone tools used by Homo erectus unearthed in Saffaqah, which is about 200 kilometers west of the capital of Saudi Arabia, Riyadh, to try to determine why the species became extinct.

First thought to have been developed about 1.9 million years ago in Africa, Homo erectus was the first primitive hominid to become a true global traveler.

It is known that they migrated from Africa to Eurasia, extending to Georgia, Sri Lanka, China and Indonesia.

However, the hominid eventually died out about 140,000 years ago.

According to the latest findings of the National University of Australia, this can be attributed to the lack of ambition, wonder and industriousness.

"They do not really seem to have forced themselves," said lead researcher Dr. Ceri Shipton of the ANU School of Culture, History and Language.

"I do not have the feeling that they were explorers looking over the horizon, they did not have the same sense of wonder as we do," he explained.

It is believed that Homo erectus lived in hunter-gatherer societies. Archaeological evidence suggests that Homo erectus used fire and made basic stone tools.

The researchers said that this lack of amazement was evident in the way the species made their stone tools and the resources they collected.

WHO WERE HOMO ERECTUS?

First thought to have developed around 1.9 million years ago in Africa, Homo erectus was the first early human species to become a true global traveler.

It is known that they migrated from Africa to Eurasia, extending to Georgia, Sri Lanka, China and Indonesia.

They vary in size from just under five feet to more than six feet.

With a smaller brain and a heavier eyebrow than modern humans, it is believed to have been a key evolutionary step in our evolution.

It used to be that Homo erectus disappeared around 400,000 years ago.

However, this date has been drastically reduced, with more recent estimates suggesting that they went extinct 140,000 years ago.

It is believed that they have given rise to a number of different extinct human species, including Homo heidelbergensis and Homo antecessor.

It is believed that Homo erectus lived in hunter-gatherer societies and there is some evidence to suggest that they used fire and made basic stone tools.

This "laziness" combined with the inability to adapt to a changing climate probably led to the extinction of the species (skull, pictured), suggests a new article.

"To make their stone tools they would use whatever stone they could find in their camp, which were mostly of low quality compared to what the stone tool makers used," he said.

"At the site we looked at there was a large rocky outcrop of quality stone within walking distance of a small hill.

"But instead of going up the hill, they would simply use any piece that had rolled and was on the bottom."

However, when the researchers examined a rocky outcrop near a known area, they found that there were no signs of activity, artifacts or excavation of the stone.

"They knew I was there, but because they had adequate resources, they seemed to have thought," Why bother? "Said Dr. Shipton.

WHAT EVIDENCE DO WE HAVE HOMO ERECTUS WERE LAZY?

Homo erectus may have gone extinct because they were lazy, according to research from the Australian National University.

Scientists say that the "least effort strategies" for tool making and resource collection led to the fall of the primitive human species.

This "laziness" coupled with the inability to adapt to a changing climate probably led to the extinction of the species, their article suggests.

To make their stone tools, they would use any stone they could find in their camp, which were mostly of low quality compared to what the stone tool makers used, according to researchers who observed ancient populations in the Arabian Peninsula.

At the site, the researchers observed that there was a large rocky outcrop of quality stone a short distance away from a small hill.

But, instead of going up the hill, they would simply use the pieces that had fallen and were at the bottom.

When the researchers observed the rock outcrop they found that there were no signs of activity, artifacts or excavation of the stone.

This is in contrast to the makers of stone tools of later periods, including the first Homo sapiens and Neanderthals, who climbed mountains to find good quality stone and transport it over long distances.

Experts believe that a failure in technological progress, since its environment dried up in a desert, also contributed to the disappearance of the population.

This contrasts with the hominids of later times, including the first Homo sapiens and Neanderthals, whose evidence shows mountains climbed to find good quality stone and transport it over long distances to use it in their tools.

Dr. Shipton said that a failure in technological progress, since its environment dried up in a desert, also contributed to the disappearance of the population.

"Not only were they lazy, but they were also very conservative," said Dr. Shipton.

"The sediment samples showed that the environment around them was changing, but they were doing exactly the same with their tools," said Dr. Shipton.

"There was no progression at all, and their tools are never far from these now dry river beds." I think in the end the environment became too dry for them, "Dr. Shipton said.
