A Scientific Surprise .. Contemporary Month of Ancient Egyptians | Science

The mammoth is a member of the elephant family, reaching a height of 4 to 5 meters up to its shoulders. A prehistoric man, and his bones were useful in construction, and his ivory was used to carve small statues.

The U.S.-Canadian joint research team was able to uncover the secrets of ancient life in the Glondike area, located in the center of the Yukon province in the northwestern United States.

Due to this discovery, the history of some animals, such as the woolly mammoth and the North American horse, was rewritten.

Revealing spoon

And step Studying – Published in the journal Nature Communications on December 8 – The team used several tablespoons of Canadian permafrost, which contained various DNAs of animals and plants that have lived in the area for the past 30 years. A thousand years ago.

The team used DNA enrichment techniques developed at McMaster University in Canada Report The official journal that the DNA was isolated and examined; This helped researchers to reconstruct animal and plant communities during this period of Earth’s history.

In particular, the researchers focused on different time points during the transition from the Pleistocene to the Holocene, where the climate was unstable 11 to 14,000 years ago. Such as mammoths, mastodons (a large animal that looks like an elephant) and saber-toothed cats.

New results

But this DNA study revealed some surprises, it showed Studying Evidence that both the woolly mammoth and the North American horse were extinct about 5,000 years ago, contrary to what scientists previously believed.

This means that the woolly mammoth lived in ancient Egyptian civilization, but the mammoth did not spread to Africa; On the contrary, he lived in many parts of northern Siberia and Europe, as well as the northern part of the North American continent.

The last destruction

The mammoth is an animal of the family, reaching a height of about 4 to 5 meters up to the shoulder. , And ivory was used to carve small statues. Researchers in this range say that not only climate change but also human activities are responsible for the extinction of mammoths.

This causes us to think about what is currently happening on Earth, as we are already facing global warming and we are already exhausting the Earth’s environment by depleting the Earth’s resources. A massive extinction in which animals are disappearing at an unprecedented rate.
