Showing results for "The Tree" in Evolution

Our understanding of the ‘tree of life’, with powerful implications for human genetics, human health and our own human nature, has recently completely changed. This book is about a new method of telling the story of life on earth - through molecular phylogenetics. It involves a fairly simple method - the reading of the deep history of life by looking at the variation in protein molecules found in living organisms. For instance, we now know that roughly eight percent of the human genome arrived not through traditional inheritance from directly ancestral forms, but sideways by viral infection.

Science's greatest puzzle is where did we come from and how did we get here. This book shows how telling this story depends on understanding the gigantic family tree - the Tree of Life - that records the relationships between all species of life on earth - from humans, fish and butterflies to oak trees, mushrooms and bacteria. Knowing the Tree of Life unlocks the distant past letting us travel back in time to follow the twists and turns of life's history; it is what allows us to tell the very personal story that began four billion years ago.
