"History of Human Origins" Pyongren: All Pyongans are bipedal

Pong man

Pong, a genus of paranthropus under the Terran race, is a bipedal family of humans, probably evolved from Australopithecus australopithecus. All of the plutoes walked bipedally, and most lived in the generations before the prevalence of the human race. The Pong people appeared about 2.7 million years ago. Most of the brains of people are only 40% the size of today's humans. The size of the species varies somewhat, with most of them standing about 1.3-1.4 meters tall and stout. The Pong people lived in woodlands, not in the steppes like australopithecus. People behave differently from human beings, they are less adaptable to the environment, and they are not very intelligent. This can be seen from the fact that their physiology is still suitable for eating insects and plants. In this way, they need to rely on the environment and do not eat more different kinds of food like people (such as capable people).

1. Classification

It is said that the Ethiopian Pong, The Bao's Pong, and the Roebacean pony should belong to australopithecus. The emergence of stout prongs may have come from convergent or divergent evolution. Therefore, there is still no consensus on the classification of these three species, including the genus P. Over the past half-century, most scholars have placed all species of Australopithecus and Pleiades in the same genus, and both genera have been used and accepted.

2. Appear

Most Australopithecus species: Australopithecus afarensis, Australopithecus Africanus, and Australopithecus on the lake lost their fossil records after the emergence of early humans, or were simply the ancestors of Noh, while the Bouchers and Ethiopians continued to evolve along branches unrelated to early humans. It lived with other early human genera ( such as noctors , craftsmen , and even Homo erectus ) . Both Australopithecus Alpha and Australopithecus by the lake disappeared at this time. Although the skull remains of Australopithecus australopithecus and Australopithecus have morphological differences, the subranial remains are very similar. The cranial teeth of the prong are larger , and the sagittal crest on the skull is a bit like a gorilla.

3. Smart

The brain shell of the Prongian is smaller than that of the genus Human, but larger than that of australopithecus. The Pong people are associated with stone tools in both southern and Eastern Africa, but whether they made them is controversial. Most scholars believe that early human beings also knew how to make tools. [2] Most of the characters don't seem to use language or fire.

4. Discovery

Part of the skull and jaws of the Roebacean were discovered in 1938 in Cromudley, South Africa. Robert Broom described these skulls as new genera and species. This site was excavated again in 1993 and is estimated to have belonged to 1.95 million years ago.

The Bowers were discovered on 17 July 1959 by Mary Leakey in the Oduay Gorge in Tanzania. Mary was working alone, while her husband, Louis Leakey, was recuperating in the camp. She hurried back to the camp, and Louis recovered quickly when he learned of this. They didn't dig until they shot the site. Luise originally recorded the remains as titanohomo mirabilis, reflecting their belief that the remains were close to humans. Later Louise and Mary called it "Dear Boy". Excavations stopped on August 7, when the remains were with tools and animal bones.

The fossils were later published in Nature, but were delayed due to editorial problems, and Louis classified them in Bloom's Australopithecus and named them Bauer's East Africans. He placed it in different genera because it was found that the remains were found in more than 20 places that were different from Australopithecus.

Bloom died in 1951, while Raymond Dart is still alive. Dart burst into tears at the sight of Louis's Bower's East Africans. After studying Bloom's genus Pyro, Louis refused to identify with the genus because he believed that The East Africans of Bowers were the ancestors of the genus. His decision at the time was largely based on the large canine teeth of the East Africans.

Later, Louis presented The East Africans of Bauer at the Congress of the Belgian Congo, but the Congress blamed him for establishing an independent genus. Fortunately, a sentence from Dart saved him: "... I wonder what will happen if Mrs. Price meets her dear boy at night. ”

The controversy over its name continued and led to a rupture between Louis and Sir Wilfrid le gros clark. On the other hand, it links the Niche family to melville bell grosvenor. As a result, the niches have become international icons, and have been supported in terms of research funding. The East Africans of Bowers eventually became part of the problems of australopithecus and australopithecus and australis.
