Homo Erectus Is A Hominid Species That Originated

Homo Erectus arrived in Java approximately 1.3 million years ago, Homo Erectus is a hominid species that originated in equatorial Africa. The Eurasian Caucasus region reached the island of Java, Indonesia, some 300 million years ago, according to an analysis of zirconia grains in tuffs from an archeological site in Sangiran, 300,000 years later, as previously thought.

Antiquarian hominind: The archaeological site of Sangiran, a World Heritage Site in Central Java, is widely considered one of the most important sites for understanding the evolution of our first ancestors and their slow march around the world. It has produced a constant flow of Homo Erectus found since 1936, based on 100 samples so far.

However, despite decades of research, the chronology of the Sangiran site remains uncertain and controversial, particularly at the time of the first appearance of Homo Erectus in the region. To resolve this long-standing chronological dispute, Dr. of Japan’s National Museum of Nature and Science.

Shuji Matsuura and zircon used a combination of fission track and uranium / lead (U / Pub) to determine the age of the grain. Above, below and within the impacting layers of the fossil deposits of the conglomerate. They discovered that the first date of appearance of homind Sangarin is 1.3 million years ago and 1.5 million years earlier.

“Regarding the date of the first appearance of Homo Erectus in the Sangiran region, our results provide a possible date of 1.3 million years ago and a maximum possible date of 1.45 million years,” the researchers said . “Another hominid specimen that is claimed to be the oldest Homo Erectus in Java is the Mojocorto skull from the perch site in East Java,” he said.

  • “This skull is now at least 1.49 million years old.”
  • “Therefore, the hominid dispersion in Java was resolved less than 1.5 million years ago.”
  • The findings were published in the January 10 issue of the journal Science.

Archaic hominids arrived in the Philippines 700,000 years ago. An international team of scientists has discovered 57 stone and bone tools of butcher’s animals in Kalinga, in the Cagayan Valley, in northern Luzon, the largest and largest island in the Philippines.

With an almost complete skeleton of extinct rhino philosophers showing clear signs of extinction, the team unearthed six cores, 49 scales and two possible hammer stones. Many Rhinoceros philippinensis bones had cut marks and the bones of the left and right humerus had bruises from hammer stones, presumably to gain access to the bone marrow.

Other fossils found at the Kalinga site include stegodons, Philippine brown deer, freshwater turtles and monitor lizards. Fossil and stone tools were found in the soil bed between 777,000 and 631,000 years ago. This conclusion was reached by combining several dating methods, confirming that Rhino’s carnage took place some 700,000 years ago.

“Kalinga alters our understanding of hominid colonization in the Philippines,” the researchers said. “Prior to this investigation, the earliest evidence of hominids in the region was a 67,000-year-old foot bone found in a nearby Cauva cave.” This suggests that the spread of major hominids throughout the region has increased many times and that the Philippines may have played a central role.

It was very likely that these first humans extended from north to south along the lazons as one of the rocks that travel south through the Southeast Asia of the island and, finally, to ancestral populations. To give In light of reaching the floors that led to the birth of Homo flippensis, team members Dr. Gerrit van den Berg is a researcher at the Center for Archaeological Sciences at the University of Wollongong, Australia.

“Our hypothesis is that the ancestors of Homo fluorescens came from the north, instead of traveling east from Java and Bali.” Until recently, it was believed that the main housewives could not reach other islands of Luzon and Wallacea (islands east of the Wallace Line, separated from the rest of Asia.

Australia by deep water) because it was believed they were not supposed to have boats (west of the Wallace line joined the mainland when the sea surface was low). However, the discovery of Homo florescensis on the Indonesian island of Floors in 2003 and other recent discoveries in neighboring Sulawesi suggest that the hominids were in Velasi a long time ago.

Recently exposed evidence suggests that the ancestors of Homo florescensis were on the floors 700,000 years ago, at the same time that the hominins were present in the lugin. Dr. “The spread of organisms across the Vulcan Islands supports the theory of hominid colonialism,” said van den Berg.

“If you look at fossils and recent organisms, you see that there is a weakness as you move from north to south: (i) In Luzon you will find scythes, elephants, giant rats, rhinos, deer, large reptiles and a variety.”

Water fossils are found. Water buffalo; (ii) In Sulawesi, the fossil is already bad; there is no evidence of rhinos or deer entering there; (iii) Then, in the floats, you only have stegodone, drag of Human Komodo and giant rat, which was everything.

“If the animals have accidentally reached these islands by entering the sea and following the currents of the south, it is expected that there will be fewer species in the south, and what we see is that.” While it is unlikely, if not probable, that the first human settlers in the Philippines could build simple rafts, the team believes that they are more than likely to occur by accident.

Dr. Van den Berg said: “They must have been caught in a tsunami and gone to the ocean. Such strange and accidental incidents are responsible for these human and animal movements.” This area is Technically active, so tsunamis are common and grow every hundred years or so.

In addition to the fact that he made stone tools, scientists know very little about the butchers of rhino philosophers in Kalinga. Dr. van van Berg said: “Possibly they were related to Homo erectus, and most likely the ancestors of humans found in the cave of Callao: modern humans did not arrive in the Philippines until about 50,000 years ago.” Van den Berg said.

The team’s results appear in the Nature Journal.
