Broadcast (2003) Where did we come from? Spencer Wells, a 33 year old population geneticist, has closed the door on his laboratory and is embarking on the biggest adventure of his life. His mission to retrace the most extraordinary journey of all time, a journey that involves every man, woman and child alive today. He offers his thoughts on this puzzling question, employing the latest in DNA research and technology to track the migration of humanity across the globe.

By collecting blood samples from thousands of men living in isolated tribes around the world and analyzing their DNA, Spencer and his colleagues discovered that all humans alive today can be traced back to a small tribe of hunter-gatherers who lived in Africa 60,000 years ago. Following this genetic trail, Spencer has charted the ancient journey of our ancestors as they populated the planet.

Spencer scours the world for indigenous people with deep roots in one place, asking for samples of DNA to test, in order to piece together our "big family" genetic tree. In Indiana Jones mode, Wells tacks down common ancestors and comes up with some surprising candidates. He shows with DNA results the diverse ways in which people and tribes react to the news of what science says about their arrival and relations. View this as adventure travel or as a painless way to begin your genetic literacy.

I show this docu to every single class I teach, since it came out. Three yrs ago, we even sent a student's DNA off to their lab for analysis and her map of ancestral migration came back. Being a decendant of slaves brought to the US, her map was quite simple, only showing a small line from eastern to west coast of Africa. We were going to send DNA from a student who said she had Cherokee blood. That would have been interesting to study. Thanks for downloading this. Love science.

Nobody likes to hear that their creation story is a myth.

[DarthRacist]

Furthermore, they're presenting the old story of the migration into the Americas, despite mounting evidence that this particular story is just that, a single story, and there are other stories to be told.

There is a definite Marxist, anti-Western mantra in Western academia.

[DarthRacist]

This is inane. I don't descend from Australian Aboriginals. Period.

[DarthRacist]

This 'documentary' makes far too many assumptions. Assumptions that will be disproven. Man's evolution was more varied and complex than a simple, "We all came out of Africa 50,000 years ago."

[DarthRacist]

Evolution implies difference. Though it's one species, this species has many variations. Evolution is change based on the stress of existence, of environment. Therefore, genes change.

I love it how certain ethnic groups think they are more special than others because their god made them and then genetic science prooves otherwise.

what the hell are you talking about? Where did you learn your 'biology' ?

@PsychedelicRoadshow Sure they could have made the etching that way but why? That's a very difficult way to do it for no real purpose.

[PsychedelicRoadshow]

Although I have no formal scientific training, it seems to me that finding just one man in the southern tip of India with an ancient African Y marker & then to definitively claim that "you found a missing link" as opposed to possibly "a romantic affair several generations prior" does not appear to be sound science.

Also, the ceiling cave etching in France could have been done with an extension stick/tool or merely sitting/standing on another one's shoulders???

Insight and/or criticism now open.
