Unearthing the Brink: Pinpointed the Moment Humanity Almost Went Extinct

Ancient humans nearly became extinct about 900,000 years ago, reducing the world population to about 1,280 reproductive individuals, according to a new study. Moreover, the ancestral population of early humans remained very small for about 117,000 years.

Humanity Almost Went Extinct The analysis, published August 31 in the journal Science, is based on a new computer model developed by a group of scientists from China, Italy and the United States.

This statistical method used genetic information from 3,154 modern human genomes.

According to research, about 98.7% of human ancestors were lost. The researchers argue that this population decline is linked to a gap in the fossil record and could lead to the emergence of a new species of hominin, the common ancestor of modern humans, Homo sapiens and Neanderthals. ing.

In a landmark revelation that challenges our understanding of human history, a group of scientists claim to have identified a pivotal moment in the distant past when human existence was at stake. This discovery sheds new light on the challenges our ancestors faced and underscores humanity’s resilience and Humanity Almost Went Extinct.

Surprising Discovery

Through careful examination and analysis of ancient genetic data, archaeologists and geneticists have uncovered significant events that occurred thousands of years ago. This event is believed to be a volcanic eruption that plunged the Earth into a period of dramatic global cooling. The Toba Catastrophe

The event in question is believed to be the eruption of Mount Toba in Indonesia about 74,000 years ago. This volcanic eruption was one of the most violent eruptions in Earth’s history. A cloud of volcanic ash covered the sun, causing a year-long volcanic winter. This has caused global temperatures to drop significantly, causing widespread environmental destruction and food shortages.

Human impact

The Toba eruption had a great impact on early humans. It is estimated that the epidemic reduced the human population to just a few thousand and scattered them around the world. These small, isolated groups faced extreme environmental challenges and limited resources, and survival was not guaranteed.

Resilience and Adaptability

What’s really remarkable is that our ancestors were able to withstand these devastating conditions. Humanity Almost Went Extinct They show incredible resilience and adaptability, finding ways to survive in some of the harshest environments on earth. Over time, they developed new tools, technologies, and social constructs that helped them overcome the challenges they faced.

Genetic Bottleneck

The Toba eruption is also thought to have left a genetic imprint on modern humans. The small population size during this period probably created a genetic bottleneck and greatly reduced the diversity of the human gene pool. Remarkably, this genetic bottleneck may be the reason why all modern humans share a high level of genetic similarity.

Today’s Lesson

The discovery of this pivotal moment in human history is a poignant reminder of the resilience of our species. This underscores our ability to adapt and overcome even the most difficult challenges. In today’s world facing global crises ranging from environmental problems to pandemics, the story of the Toba Pandemic reminds us that as a species we have faced adversity before and have come out stronger. It reminds me. Furthermore, this revelation emphasizes the importance of understanding our past. By examining the struggles and triumphs of our ancestors, we can gain valuable insight into our human capacity to innovate, collaborate, and survive.

In summary, identifying the moment when humanity nearly went extinct is a remarkable scientific achievement that reconstructs our understanding of our own history. It is a testament to the tenacity and adaptability of our species and a source of inspiration as we face the challenges of our time.

“This new discovery opens up a new field in human evolution, because we can understand where these individuals lived, how they survived catastrophic climate change, and how human brains developed. It raises many questions, such as whether natural selection accelerated while being bottlenecked and restricted,” said lead author Yi. -Xuan Pang, an evolutionary functional genomics scientist at East China Normal University, said in a statement. The researchers suspect that this population bottleneck coincided with dramatic climate change during the so-called Mid-Pleistocene transition. Ice ages became longer and more intense, resulting in lower temperatures and very dry climatic conditions.

The scientists also hypothesized that fire control and climate change, which made human life more favorable, may have contributed to the subsequent rapid population growth about 813,000 years ago.

According to the authors, the earliest evidence of using fire to cook food dates back to 780,000 years ago, in what is now Israel. Humanity Almost Went Extinct

Ancient DNA has revolutionized our understanding of past populations, but the oldest human DNA dates back to about 400,000 years ago.

The computer model uses the vast amount of information contained in modern human genomes about genetic variation over time to infer the size of populations at specific points in the past. The team used genetic sequences from 10 African and 40 non-African populations.

‘Provocative’ study

In a commentary on the analysis published in the same journal, Nick Ashton, curator of the Paleolithic collections at the British Museum, and Chris Stringer, research leader in human evolution at the Natural History Museum in London, described the study as “provocative.”

The two researchers, who were not involved in the study, Humanity Almost Went Extinct said it brought “the vulnerability of early human populations into focus.”

However, Ashton and Stringer said that the fossil record, while sparse, did show that early human species lived in and outside Africa about 813,000 to 930,000 years ago — during the period of proposed population collapse, with fossils from that era found in what’s now China, Kenya, Ethiopia, Italy, Spain and the United Kingdom.

“Whatever caused the proposed bottleneck may have been limited in its effects on human populations outside the Homo sapiens lineage or its effects were short-lived,” the two researchers said in the commentary.

“The proposed bottleneck needs to be tested against human and archaeological evidence,” they added.
