Dog Domestication Wasn’t a Single Event. Most Dogs Went Extinct.

Описание: Dogs weren’t domesticated once.
They were domesticated multiple times — and most of those dogs disappeared.

For decades, scientists searched for a single origin of the domestic dog.
Ancient DNA has now revealed something far more unsettling.

Dogs were domesticated independently in different regions, from different wolf populations.
Some of those dog populations lived with humans for thousands of years — and then went extinct.

In this documentary, we explore:
• multiple independent dog domestication events
• extinct dog lineages erased from history
• ancient DNA and population replacement
• why modern dogs are genetic hybrids
• what this tells us about evolution and extinction

This film is based on peer-reviewed research, ancient genomes, and the latest scientific consensus.

The dogs alive today are not the first dogs.
They are the survivors.

Introduction:
In a research laboratory at Oxford University, Dr. Greger Larson stares at a computer screen displaying the most comprehensive genetic analysis of dog origins ever conducted. The data represents years of work—ancient DNA from dozens of archaeological sites across three continents, genetic sequences from thousands of modern dogs, statistical models running for months.
The results are impossible.
According to the genetic evidence, dogs were domesticated twice. Once in Europe. Once in Asia. Two separate events, separated by thousands of miles and possibly thousands of years, producing two distinct dog populations that had never encountered each other.
Until they did.
Around 6,400 years ago, Asian dogs migrated westward and encountered European dogs. The two populations met, interbred, and the European dogs—the original Western domesticates—disappeared. Completely. Replaced by a hybrid population that would give rise to all modern European dogs.
But here's what makes this discovery truly mind-bending: if domestication happened twice, and one of those domestication events led to a population that went entirely extinct, how many other times did it happen? How many dog populations arose, flourished, and vanished without leaving any trace in the modern gene pool?
What if the dogs we know today are not the descendants of the first dogs, but the survivors of a process that killed most dog lineages?
Today, we journey through evidence that challenges everything we thought we knew about dogs and their origins...
Prepare yourselves. We begin.
