The Disaster That Nearly Annihilated Humanity Reveals the History of Evolution

LONDON – Before Homo sapiens evolved, our ancestors did almost extinct. Evidence from various sources supports this theory, but the exact date is still debated.

One study shows this event occurred 1.15 million years ago, while another study puts it 200,000 years later.

Reanalysis of the data shows a more recent figure, namely 900,000 last year. This finding may shed light on one of the most important events in human evolutionary history.

A species’ genome can store evidence of critical periods when its population experienced drastic decline. Inbreeding resulting from these small populations can increase the risk of extinction for generations, but some species have managed to recover.

In the case of humans, this obstacle occurred in our ancestors, possibly Homo erectus, long before Homo sapiens appeared. Traces of this event can still be found in the genome of modern humans.

Geneticists and paleontologists do not agree on the exact time. This difference in time estimates is an obstacle in understanding the causes of this event.

A new study claims to have resolved the contradiction and provided evidence of a previously unidentified human migration in the process.

This new research shows that 900,000 years ago, the Homo erectus population experienced a drastic decline. A small group of this population then migrated out of Africa, carrying genetic traces of the near-extinction event.

This migration may be driven by climate change or other factors. This migration allowed our ancestors to find new habitats and avoid extinction.

This discovery has important implications for our understanding of human evolutionary history. This shows that our ancestors experienced a critical period that almost wiped out the entire species.

The great migration that followed may have been a key factor in allowing humans to thrive and become the dominant species on Earth.

Although this new research provides important answers, many questions remain unanswered.
