Lost Animals: The Story of Extinct, Endangered, and Rediscovered Species is a fantastic and gorgeous book by John Whitfield and published through the Smithsonian Institute. This book contains gorgeous pictures and detailed descriptions of some of Life's most interesting and amazing creatures. The book starts in the Cambrian, and works its way up to the endangered species of modern times. Some fascinating creatures abound, from a massive Rhinoceros that towered above the trees, to a five eyed shrimp-like creatures that looked so strange, a panel of scientists burst out in laughter upon seeing it. The book also looks at some of human's earliest ancestors, and discusses how modern humans may have interbred with other species of humans to create roughly what we are today. The world of the past looked so much different, and this book excels at not only showing us the wonder and mystery of prehistory, but also made this reader speculate of humanities place on this Earth, the niches we inhabited, and the way our brains developed to serve us in gathering and hunting food, and how this applies to and is completely related to how we live our modern lives. Modern humans are only 10000 years old, a blip in the evolutionary timescale - we have not developed much past what we would have been as a symbiotic part of the ecosystem. Even so, the way we gather, think and act has had such an impact on this Earth, that it is posited we are ushering in a sixth extinction event, and we may have been responsible for the disappearance of mega-fauna in the recent past. All in all, a fantastic read. Quick, engaging, great pictures, and some fascinating commentary.
