Hi, I have a question about common ancestry I'm sure, thanks. Which The following indicates no evidence of a common ancestor a.most morphological characters shared between agencies b.comparable regions in DNA sequences d.features c.morphological features fossils that are evidence of convergent evolution

Deep Ancestry (Paperback) $25.93 The fossil record locates human origins in Africa, but little is known about the great journey that took Homo sapiens to the far reaches of the Earth. How did we, each of us, end up where we are? Why do we appear in such a wide array of different colors and features? Such questions are even more amazing in light of genetic evidence that we are all related–descended from a com- mon African ancestor who lived only 60,000 years ago. Thanks to new genetic testing methods, we now know that the greatest history book ever written is the one hidden in our DNA.In Deep Ancestry, geneticist and explorer Spencer Wells unravels the slight changes in our DNA over time to tell the ancient story of our shared human journey. He also details the current work of Genographic Project–the landmark study that will assemble the world`s largest collection of DNA samples to map how humankind populated the planet. He describes how the Project uses sophisticated computer analysis of DNA contributed by hundreds of thousands of people–including indigenous populations and the general public–to reveal man`s migratory history and to better understand the connections and differences that make up the human race. The narrative works backward, starting from today and gradually working its way to humankind`s common ancestors. From the beginning, the book taps into a reader`s interest in genealogy, family history, and ethnic identity. Most of us have a decent sense of our family history, but eventually we all hit a brick wall. DNA takes us beyond it, and this is the unifying theme that will lead us from the stories of the present into the realm of deep ancestry. Now in a thoroughly revised second edition, Deep Ancestry represents the very latest research on where we came from and relates it to our own personal quest to discover the deep ancestry behind our family genealogies and touch the depths of our common origins.For more information about the Genogr |

Deep Ancestry by Wells, Spencer Edition ILL, 0 $20.49 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. |
