How could a relatively simple chemical code give rise to the complexity of a human being? How could our human genome have evolved? And how does it actually work?
Over the past 50 years we have deciphered the inner workings of the human genome. From the basic structure of DNA through to the complete sequence of the code, what first appeared to be simple is actually a complex and beautiful three-dimensional world that makes each of us who we are.
In The Mysterious World of the Human Genome acclaimed science writer Frank Ryan leads us through the most exciting scientific discoveries of the last 50 years, revealing how this science has unlocked the cure of some genetic diseases, developed the use of DNA in forensic science and paternity testing, helped us trace our ancestors and provided a definitive map for the movement of humans out of Africa. This scientific journey has had a profound impact on our understanding of the evolution of life itself, through the role of the most ancient of organisms in our basic biology all the way to the revelation that our most recent ancestor, Homo neanderthalensis, lives on in many of us.
In the ever more complicated world of the human genome, this is the first book to explain how the human genome actually works as a whole and how that knowledge will have a profound effect on our understanding of where we have come from and where we are likely to be going in the future.

SOME GERMS ARE OUT TO GET US. . . . But we shouldn’t let a delinquent, pathogenic minority taint our view of the other 99.9 per cent.
The microbes living on and inside us outnumber the cells in our bodies three to one. Many provide services on which our well-being, our moods, our very lives depend. They help to digest our food and operate the immune system. They trade information about potential mates when we kiss. They alert the brain to problems in different locations around the body. The balance of their populations in our gut is a crucial factor in our physical and mental health.
The effect of germs on our lives is not, however, a one-way street. We can help their efforts by the way we lead our lives.
The Germ Files is a one-stop source of the most up-to-date, life-changing information on our relationship with microbes, presented in concise and highly readable items grouped by theme. Areas covered include health, hygiene, sex, childcare, nutrition and dieting.
The Germ Files will answer your questions about everything from preventing flu to selecting probiotics, while constantly surprising you with revelations about the miraculous workings of the microscopic world.

Making Peace with Microbes
Public sanitation and antibiotic drugs have brought about historic increases in the human life span; they have also unintentionally produced new health crises by disrupting the intimate, age-old balance between humans and the microorganisms that inhabit our bodies and our environment. As a result, antibiotic resistance now ranks among the gravest medical problems of modern times. Good Germs, Bad Germs addresses not only this issue but also what has become known as the "hygiene hypothesis"— an argument that links the over-sanitation of modern life to now-epidemic increases in immune and other disorders. In telling the story of what went terribly wrong in our war on germs, Jessica Snyder Sachs explores our emerging understanding of the symbiotic relationship between the human body and its resident microbes—which outnumber its human cells by a factor of nine to one! The book also offers a hopeful look into a future in which antibiotics will be designed and used more wisely, and beyond that, to a day when we may replace antibacterial drugs and cleansers with bacterial ones—each custom-designed for maximum health benefits.
