After several million years of jostling for ecological space, only one survivor from a host of hominid species remains standing: us. Human beings are extraordinary creatures, and it is the unprecedented human brain that makes them so. In this delightfully accessible book, the authors present the first full, step-by-step account of the evolution of the brain and nervous system. Tapping the very latest findings in evolutionary biology, neuroscience, and molecular biology, Rob DeSalle and Ian Tattersall explain how the cognitive gulf that separates us from all other living creatures could have occurred. They discuss the development and uniqueness of human consciousness, how human and nonhuman brains work, the roles of different nerve cells, the importance of memory and language in brain functions, and much more. Our brains, they conclude, are the product of a lengthy and supremely untidy history--an evolutionary process of many zigs and zags--that has accidentally resulted in a splendidly eccentric and creative product.
Genome sequencing enables scientists to study genes over time and to test the genetic variability of any form of life, from bacteria to mammals. Thanks to advances in molecular genetics, scientists can now determine an animal's degree of inbreeding or compare genetic variation of a captive species to wild or natural populations. Mapping an organism's genetic makeup recasts such terms as biodiversity and species and enables the conservation of rare or threatened species, populations, and genes. By introducing a new paradigm for studying and preserving life at a variety of levels, genomics offers solutions to previously intractable problems in understanding the biology of complex organisms and creates new tools for preserving the patterns and processes of life on this planet. Featuring a number of high-profile researchers, this volume introduces the use of molecular genetics in conservation biology and provides a historical perspective on the opportunities and challenges presented by new technologies. It discusses zoo-, museum-, and herbarium-based biological collections, which have expanded over the past decade, and covers the promises and problems of genomic and reproductive technology. The collection concludes with the philosophical and legal issues of conservation genetics and their potential effects on public policy.

Ever since the recognition of the Neanderthals as an archaic form of human in the mid-nineteenth century, the fossilized bones of extinct humans have been used by paleoanthropologists to explore human origins. These bones tell the story of how the earliest humans first emerged in Africa some 6 to 7 million years ago. The bones also reveal that as humans became anatomically and behaviorally more modern, they swept out of Africa in waves into Asia, Europe, and finally into the New World. Even as paleoanthropologists continued to make important discoveries, experts in genetics were looking at the human species from a very different angle. In 1953 James Watson and Francis Crick first envisioned the double helix structure of DNA, the basic building block of all life. In the 1970s it was shown that humans share 98.7 percent of their genes with the great apes--that in fact genetically we are more closely related to chimpanzees than chimpanzees are to gorillas. And most recently the entire human genome has been mapped--we now know where each of the genes are located on the DNA strands that make up our chromosomes. In Human Origins: What Bones and Genomes Tell Us about Ourselves, two of the worlds foremost scientists, geneticist Rob DeSalle and paleoanthropologist Ian Tattersall, show how research into the human genome confirms what fossil bones have told us about human origins. This unprecedented integration of the fossil and genomic records provides the most complete understanding possible of humanity's place in nature, its emergence from the rest of the living world, and the evolutionary processes that have molded human populations to be what they are today.
Biology, the study of life, directly applies to your health, life, and future in ways as simple as making daily food choices or as complex as deciding which career to pursue.
