A Pocket History of Human Evolution, How We Became Sapiens, by Silvana Condemi and François Savatier (audio book 3.3 hours). This book is full of so-called “science” so I am going to summarize it in a way that the common person (you) can understand. Long, long, long, long ago human-like animals were developing into several distinct species. None were attractive in the modern sense. A couple of them became predominate: Neanderthals and what became modern man. Despite their differences, they had carnal relations, much like liberals and conservatives sometimes do in a dark bar under the influence of beer. (You can decide whether liberals or conservatives are the equivalent of Neanderthals.) For a variety of reasons, modern humans crowded out the Neanderthals, in large part because they progressed from Hunter-gatherers to people who liked broccoli, i.e. agriculturists. Brains got bigger, languages developed, hordes became tribes, and other changes occurred (some of which can be attributed to evolution, otherwise known as magic). Bipedal humans from Africa travelled to lots of vacation destinations, and like people visiting Colorado, many chose to stay. This was long, long, long, long ago when the earth had not yet been damaged by climate deniers, and when land bridges existed between some continents. Due to a shortage of sunscreen some people became darker. Others didn’t due to being subjected to less direct sunlight. People began hanging out together, governments emerged (but from what sinkholes they came no one knows), tools became refined, fire was invented, the Beatles invaded America, and humans began destroying the planet due to nearly unlimited procreation compounded by the failure of many people to die as God intended. So, in short, humans won the battle of species, invented knives, wheels, and Viagra, and they are now doomed because of conservatives’ aversion to birth control. You may want read the book yourself.
