On this day, 31 years ago, September 22, 1994 (August 17, 1994 in the lunar calendar), an international team of archaeologists discovered the earliest human fossils. On September 22, 1994, an international team of archaeologists discovered the remains of the earliest ancestors of mankind 4.4 million years ago in Ethiopia, thus filling the gap in the evolutionary history between humans and apes. The British journal Nature pointed out in a report that this discovery allows scientists to conduct a more detailed study of the origin of mankind. An international team composed of Dr. Asfu from the Ministry of Culture of Ethiopia, Professor Tim White from the University of California in the United States, and Professor Suwa from the University of Tokyo in Japan have discovered a total of 50 skulls belonging to 17 to 20 members of the hominid family 4.4 million years ago in the village of Arashus in the Central Awash Valley, 23O kilometers northeast of Addis Ababa in the past two years. Tooth and upper arm bone fragments. These fragments are the remnants of the earliest direct ancestors of humans discovered so far. The oldest human ancestor fossil before this is the southern ancient "Lucy" fossil discovered by Professor Suwa of the University of Tokyo, which is 3.6 million years old. Evidence provided by teeth suggests that these newly discovered early humans may have belonged to a period when apes and humans were just "separated". This period belongs to a link that scientists want to find but have never found. In recent years, genetic evidence collected by scientists from modern humans and apes shows that the "separation" of humans and apes occurred between 5 million and 9 million years ago. However, the findings of this international team of scientists suggest that the "separation" of apes may have occurred in the latter half of this period, about 4.5 million to 5.5 million years ago. Scientists have named their newly discovered fossil Australopithecus roots, which scientists say were basically crappers but also carnivorous. Edible may be a small wild animal hunted down by a group. They don't know how to make stone tools and sleep in trees for safety. Although they can walk upright like modern humans, their intelligence is still at the ape-like stage. Professor Tim White said the discovery allowed us to better study human ancestors from the roots of human family trees for the first time, and also confirmed Charles Darwin's prediction that the earliest roots of human evolution were found in Africa.
