The primitive man was discovered in the year 1856, but even today the mystery remains in many cases. However, through the ongoing research around the world, new facts keep coming out from time to time. Recently a discovery has come to the fore in this episode. Professor Peter C Keizerberg of the University of Copenhagen, Professor P Mark Maslin of Earth System Science, and Trine Kellberg Nielsen, Associate Professor at Aarhus University, said that primitive humans died 40,000 years ago, but their DNA has not been found on Earth. It is believed that this research will help uncover many new facts about primitive man in the coming time.
Primitive man is considered a reflection of human civilization. Till now, work has been done on the concept that our cultural trends, social norms, and scientific standards are somewhere in the orderly development of the behavior of primitive humans. In a way, we have been considering them as our ancestors. In such a situation, this discovery of three scientists including Keizerberg raises the question that if the primitive humans became extinct. If their name mark (not getting DNA) was erased, then how did human civilization develop? What was the relationship between primitive man and human civilization and how was this relationship formed?
Primitive humans came to earth four lakh years ago
According to the research done so far, primitive humans evolved four lakh years ago. homo heidelbergensis
(of an extinct species or subspecies of ancient humans) had their ancestors and spread from the Mediterranean to Siberia. They were highly intelligent, with brains on average larger than those of Homo sapiens (the intelligent species most closely related to human civilization).
From storing food to making clothes from animal skins
He hunted big. They collected plants, fungi, and seafood. Controlled the fire for cooking. They were able to make clothes from animal skins, make beads from shells, and carve symbols on cave walls. He also created the social structure. It took care of the young, the old, and the weak. They built shelters for protection, lived in harsh winters and hot summers, and buried their dead. About 14 thousand years ago they met our ancestors and also shared the European continent.
Three possible causes of extinction
1. During the Ice Age, when there was a period of change on the earth, there was pressure on animals, and plants including their food sources. Primitive humans (Neanderthals) could not adjust to that change and gradually died out. Like dinosaurs suddenly became extinct from this earth.
2. The number of primitive humans did not exceed thousands. It lived in groups of five to 15 individuals compared to Homo sapiens. Being a small and isolated population, genetically unstable.
3. The human civilization that took birth in Africa about 60,000 years ago gradually assimilated into it and their DNN also changed sequentially.
Remains are present in the Danish museum, with 99.7 percent similarity
Even thousands of years after the extinction of primitive man, the marks left on the earth are present in the museum in Denmark. When the genome of primitive man was mapped with the most ancient DNA present in the museum, 99.7 percent similarity was found them. On this basis, it was concluded that they are our closest extinct relatives.
conclusion
Scientists have concluded in their research that the extinction of primitive humans is a lesson for the present human civilization. After ruling this earth for thousands of years, a species became extinct, because it could neither sense the danger nor adapt itself to it. Presently human activity is also changing the climate of the earth. In such a situation, human civilization should make collective efforts to preserve its existence. This extinction of primitive humans reminds us that we should never take our existence for granted.
