Science tells us we're all related—one vast family sharing a common ancestor who lived in Africa 60,000 years ago. But countless questions remain about our great journey from the birthplace of Homo sapiens to the ends of the Earth. How did we end up where we are? When did we get there? Why do we display such a wide range of colors and features? The fossil record offers some answers, but exciting new genetic research reveals many more, since our DNA carries a complete chronicle of our species and its migrations.
In Deep Ancestry, scientist and explorer Spencer Wells shows how tiny genetic changes add up over time into a fascinating story. Using scores of real-life examples, helpful analogies, and detailed diagrams and illustrations, he translates complicated concepts into accessible language and explains exactly how each and every individual's DNA contributes another piece to the jigsaw puzzle of human history. The book takes readers inside the Genographic Project, the landmark study now assembling the world's largest collection of population genetic DNA samples and employing the latest in testing technology and computer analysis to examine hundreds of thousands of genetic profiles from all over the globe.
Traveling backward through time from today's scattered billions to the handful of early humans who are ancestors to us all, Deep Ancestry shows how universal our human heritage really is. It combines sophisticated science with our compelling interest in family history and ethnic identity—and transcends humankind's shallow distinctions and superficial differences to touch the depths of our common origins.
Tomamos prestada la máquina del tiempo o el auto del Dr. Emmett Brown De "Volver al Futuro" y regresamos a través de los estudios hechos con el ADN y el ADN mitocondrial a nuestros primeros antepasados, aquellos que vieron una Tierra distinta a la de hoy, sufriendo y viviendo con más dureza que hoy, en un medioambiente hostil pero generoso, con una visión cósmica diferente a la actual. Las Raíces de nuestra especie. Un viaje épico.
We provided the time machine or the car of Dr. Emmett Brown of "Back to the Future" and returned through the studies with the DNA and the mitochondrial DNA to our first ancestors, those who saw a land other than that of today, suffering and living with more harshly than today, in a hostile environment but generous, with a cosmic vision other than the current. The Roots of our species. A epic trip.
