But evolutionary biologists also point out many examples of contingency, cases where the tiniest change--a random mutation or an ancient butterfly sneeze--caused evolution to take a completely different course. What role does each force really play in the constantly changing natural world? Are the plants and animals that exist today, and we humans ourselves, inevitabilities or evolutionary freaks? And what does that say about life on other planets?Jonathan Losos reveals what the latest breakthroughs in evolutionary biology can tell us about one of the greatest ongoing debates in science. He takes us around the globe to meet the researchers who are solving the deepest mysteries of life on Earth through their work in experimental evolutionary science. Losos himself is one of the leaders in this exciting new field, and he illustrates how experiments with guppies, fruit flies, bacteria, foxes, and field mice, along with his own work with anole lizards on Caribbean islands, are rewinding the tape of life to reveal just how rapid and predictable evolution can be.Improbable Destinies will change the way we think and talk about evolution. Losos's insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.

    Humans: from the beginning will appeal to anybody who reads about these discoveries, is intrigued by them, and would like to know more about prehistory. Now brought fully up to date for 2015, Humans: from the beginning is a single-volume guide to the human past. Drawing upon expert literature and the latest multi-disciplinary research, this rigorous but accessible book traces the whole of the human story from the first apes to the first cities. The end product of five years of research, it has also been planned from the ground up to take advantage of the eBook format and ease access to visual matter, references and glossary items. Humans: from the beginning is written for the non-specialist, but it is sufficiently comprehensive in scope, rigorous in content, and well-referenced to serve as an ideal ‘one-stop’ text not only for undergraduate students of relevant disciplines, but also to postgraduates, researchers and other academics seeking to broaden their knowledge. This 32-chapter work presents an even-handed coverage of topics including: • How climate change has long played a pivotal role in our affairs and those of our ancestors. • How humans evolved from apes at a time when the apes were facing extinction. • Why the last common ancestor of humans and chimpanzees (our closest living relatives) might have been more like a human than a chimpanzee. • A possible Asian rather than African origin for the earliest humans. • Why the Neanderthals were not the dimwits of popular imagination. • How language and modern human behaviour evolved: an examination of theories including those of Robin Dunbar, Steven Mithen and Derek Bickerton. • How the small group of modern humans that eventually colonised the whole of the non-African world might have started from Arabia rather than Africa. • David Lewis-Williams’ theory that the cave art of Ice Age Europe was linked to a shamanistic belief system that might be rooted in the very architecture of the human brain. • Why the Neolithic transition from hunter-gathering to agriculture was a lengthy process, with many down sides. • Colin Renfrew’s still-controversial theory that the spread of farming communities in Neolithic times was responsible for the languages now spoken in many parts of the world. • How an ‘Urban Revolution’ replaced egalitarian farming communities with socially-stratified kingdoms and city-states in just a few millennia. • How the complex, technological societies of today have much in common with not only the earliest states but much earlier primate societies.

    The more we discover, the more puzzling the universe appears to be. How and why are the laws of nature what they are? A philosopher and a physicist, world-renowned for their radical ideas in their fields, argue for a revolution. To keep cosmology scientific, we must replace the old view in which the universe is governed by immutable laws by a new one in which laws evolve. Then we can hope to explain them. The revolution that Roberto Mangabeira Unger and Lee Smolin propose relies on three central ideas. There is only one universe at a time. Time is real: everything in the structure and regularities of nature changes sooner or later. Mathematics, which has trouble with time, is not the oracle of nature and the prophet of science; it is simply a tool with great power and immense limitations. The argument is readily accessible to non-scientists as well as to the physicists and cosmologists whom it challenges.
