Science of Self

Lee M. Silver

4.9/5 (22930 ratings)

Description:Listening Length 12 hours and 3 minutesSome of the most profound secrets about what it means to be human are now being revealed, thanks to the amazing tools of biotechnology. The Human Genome Project, completed in 2003, opened the book on the genetic instructions that go into making a human. Now other species are being studied at the same level of detail, providing astonishing insights into the whole range of life on Earth.Armed with these and other findings, scientists are beginning to address age-old mysteries, including these:What is the difference between living organisms and nonliving things?How does DNA instruct a single-cell embryo to create a body with a brain that produces a self-conscious mind?What makes us human? Our minds, genes, appearance, or something else?Is the human species at the end of an evolutionary line, or will it evolve into something entirely different?In 24 thought-provoking lectures designed for nonscientists, The Science of Self explores these and many other questions in today's exciting field of genomics, the study of the vast storehouse of information contained within chromosomes.Your professor is Princeton University biologist Lee M. Silver, an acclaimed teacher, scientist, and author of popular books on biotechnology, genetics, and its impact on society. As a participant in the ongoing revolution in biology for the past three decades, Professor Silver has seen his field radically transformed. Even so, he says that he and his colleagues are astonished by the pace of discoveries in recent years and by how much has been learned about the human condition from studying the basic ingredients in genes. "We're teasing out all of the secrets," he marvels.Enlivened by Dr. Silver's clear and enthusiastic presentation, The Science of Self is an unrivaled opportunity to investigate this dramatic new picture of our past, present, and future as a species.DNA: Your Genetic "Hard Drive"Professor Silver begins by surveying the history of ideas about life and inheritance, from Aristotle's remarkably prescient scientific model of life to Darwin's theory of natural selection, Mendel's laws of heredity, and Watson and Crick's discovery that the molecule DNA encodes genetic information in an elegantly simple way. In one of his many vivid analogies, Professor Silver compares genetic information to music files purchased over the Internet. The music is not a material substance; it's simply a string of numbers copied to the hard drive of a computer. Similarly, the only thing that survives through the generations of life is immaterial genetic information, copied to the cellular equivalent of a hard drive, the DNA in the chromosomes and their constituent genes inside the cell nucleus.Cracking the CodeEquipped with this powerful understanding of heredity as information, you peer into the human genome to read its code, compare it with the genomes of other species, and trace how information is translated into individual humans with all of our rich diversity. In a riveting example of the details hidden in our genes, Dr. Silver recounts the results of genetic profiling recently done on his own DNA:The analysis shows that Dr. Silver has a relatively common allele, or mutation, that leads to a dopamine deficiency in one part of the brain—a trait associated with risk taking, which may explain his love of travel.His maternal line can be traced back 35,000 years to Spain and the original hunter-gatherers who invaded Europe and then retreated after the onset of the last ice age.His paternal line emerged more recently, in the last 3,000 years, among members of a Jewish tribe in Israel that left the Middle East between 2,000 and 1,000 years ago.Intriguingly, Dr. Silver has DNA markers that point to a Chinese ancestor about 300 to 500 years ago, who may have been one of the innumerable descendants of Genghis Khan!The Biotech Tool ChestPart of the fascinating story of The Science of Self involves the technological tool chest that allows scientists to decipher the intricacies of living things. These sophisticated procedures and devices are part of the biotech revolution, and Professor Silver introduces you to some of the tools in detail, so that you can understand through graphics and his descriptions how we have arrived at our current state of knowledge. For example, you investigate the following:Gene sequencing: In the early 1970s a multiyear effort decoded an unprecedented 63-letter sequence of DNA. The invention of DNA sequencer machines in the 1980s allowed the decoding of the entire human genome of 3 billion letters by 2004. A few years from now, complete genomes for any individual will be sequenced as part of routine medical care.FISH: Standing for Fluorescence In Situ Hybridization, this technique identifies major features on chromosomes. Among its many applications, FISH has been used to compare humans and chimpanzees, showing that the chrom...We have made it easy for you to find a PDF Ebooks without any digging.
