Where Did We Come From? - NOVA Science Now  ( 53 mins)


Nova ScienceNow examines where we came from. It looks at the origin of the solar system and experiments to produce chemical precursors of life. It also considers what lice can tell us about human evolution and profiles a scientist who is working on memory.


Nova: Science Now on PBS | "Where did we come from?" with host Neil DeGrasse Tyson explores the origin of our solar system and the start of life itself, how head lice figure in human evolution, and more. Journey back in time to the birth of our solar system to examine whether the key to our planet's existence might have been the explosive shockwave of an ancient supernova. Meet a chemist who has yielded a new kind of "recipe" for natural processes to assemble and create the building blocks of life. And see how the head louse, a creepy critter that's been sucking our blood for millions of years, is offering clues about our evolution.

The Migration History of Humans: DNA Study Traces Human Origins Across the Continents



The Link - Uncovering Our Earliest Ancestor – BBC ( 59 mins)

Uncovering Our Earliest Ancestor: The Link, tells the story of an important scientific development that could tell us more about where we come from.

The fossil, known as Ida, could be an indication of one of the roots of anthropoid evolution -- the point at which our primate ancestors began first developing the features that would evolve into our own.

Nat Geo Explorer-in-Residence Spencer Wells maps the history of human migration by analyzing the DNA of hundreds of thousands of people around the world.











Journey Of Man A Genetic Odyssey (PBS) ( 1 Hr: 53 mins)


How did the human race populate the world? A group of geneticists have worked on the question for a decade, arriving at a startling conclusion: the "global family tree" can be traced to one African man who lived 60,000 years ago. Dr. Spencer Wells hosts this innovative series, featuring commentary by expert scientists, historians, archaeologists, and anthropologists.


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.

Pre-Columbian trans-oceanic contact


Pre-Columbian trans-oceanic contact is interaction between indigenous peoples of the Americas who settled the Americas before 10,000 BC, and peoples of other continents (Africa, Asia, Europe, or Oceania), which occurred before the arrival of Christopher Columbus in the Caribbean in 1492. For practical purposes, travel across the Bering Straits, or the former land bridge in the same region are excluded.

Only one instance of pre-Columbian European contact – the Norse settlement at L'Anse aux Meadows in Newfoundland, Canada c. 1000 AD – is established beyond reasonable doubt.[1][2]

Many further forms of pre-Columbian contact have been proposed, based on historical accounts, archaeological finds, and cultural comparisons. However, most claims of such contact are controversial and debated, due in part to much ambiguous or circumstantial evidence cited by proponents. The scientific responses to pre-Columbian contact claims range from serious consideration in peer-reviewed publications to dismissal as fringe science or pseudoarcheology.
