Reconstructing the Tree of Life
To document the world's diversity of species and reconstruct the tree of life we need to undertake some simple but mountainous tasks. Most importantly, we need to tackle species rich groups. We need to collect, name, and classify them, and then position them on the tree of life. We need to do this systematically across all groups of organisms and b
The Tree of Life
'A DELIGHT' HENRY GEE 'BEAUTIFUL' THOMAS HALLIDAY Where do we come from and how did we get here? Come time-travelling through the history of every species that has ever lived with Professor Max Telford. A four-billion-year journey through the evolution of our planet, The Tree of Life tells the fascinating story of the gigantic family tree that records the relationships between every living thing - from humans, fish and butterflies to oak trees, mushrooms and even bacteria. Understanding how the amazing diversity of life on earth came to be is one of the greatest puzzles in biology. And this book, full of vivid and fascinating stories, takes you right inside: learn why grey wolves are more closely related to whales than to Tasmanian wolves; how geological change and environmental catastrophe left their marks on the genome; why we don't have tails but we are the only species with chins; and follow individual scientists down winding evolutionary byways and occasional dead ends in their attempts to solve this greatest of all puzzles. Along the way, we'll see how, far from being a dry representation of the dead, the tree of life is a living thing which constantly alters our perspective on the past, present and future of life on earth. From Darwin's early sketches to the vast computer generated diagrams scientists are building today, The Tree of Life explains how we can know our family tree at all and tells the epic history of the various ways it's possible to be a living thing. This is our own very personal story that began with the tiny ancestor of all life billions of years ago and ends with you and me.
Prebiotic Chemistry and the Origin of Life
This book presents an overview of current views on the origin of life and its earliest evolution. Each chapter describes key processes, environments and transition on the long road from geochemistry and astrochemistry to biochemistry and finally to the ancestors of today ́s organisms. This book combines the bottom-up and the top-down approaches to life including the origin of key chemical and structural features of living cells and the nature of abiotic factors that shaped these features in primordial environments. The book provides an overview of the topic as well as its state of the art for graduate students and newcomers to the field. It also serves as a reference for researchers in origins of life on Earth and beyond.
