This is a compendium of theories of the shape of the Earth, along with a great deal of 'Earth Mystery' lore. Richly illustrated, the Book of Earths includes many unusual theories, including Columbus' idea that the Earth is literally pear-shaped, modern theories that the Earth was originally tetrahedral, and so on. Kenton also covers many traditional theories including the ancient Babylonians and Egyptians, Hindu and Buddhist cosmology, and those of the Peruvians, Aztecs and Mongols. She also discusses modern alternative theories such as that of Reed and Koresh. Strangely enough, she misses or ignores the modern flat earth theory of Rowbotham. This is the only apparent omission in this definitive study. Kenton has no apparent axe to grind: this is simply a very readable survey of the literature if you have any interest in 'Earth mysteries"Show book
We all know the importance of mothers. They are typically as paramount in the wild as they are in human relationships. But what about fathers? In most mammals, fathers have little to no involvement in raising their offspring—and sometimes even kill the offspring sired by other fathers. How, then, can we explain modern fathers having the capacity to be highly engaged parents? In Father Nature, James Rilling explores how humans have evolved to endow modern fathers with this potential and considers why this capacity evolved in humans. Paternal caregiving is advantageous to children and to society at large, yet variable both across and within human societies. Rilling considers how to explain this variability and what social and policy changes might be implemented to increase positive paternal involvement. Along the way, Father Nature also covers the impact fathers have on children's development, the evolution of paternal caregiving, how natural selection adapted male physiology for caregiving, and what lessons an expecting father can take away from the book, as well as what benefits they themselves get from raising children, including increased longevity and "younger" brains. A beautifully written book by a father himself, Father Nature is a much-needed—and deeply rewarding—look at the science behind "good" paternal behavior in humans.Show book
In the list of popular American geological oddities and attractions, one sizeable phenomenon remains surprisingly unfamiliar to the average citizen. This may be due in part to its remote desert location, but perception of the Salton Sea in southern California is also laden with environmental concerns and is in a constant state of flux. The extensive body of inland saltwater hides a glorious commercial past and has served as an important wildlife preserve but approaches a seemingly inevitable crisis in the coming decade. The Salton Sea in not directly “on the way” to anything substantial or iconic, and is situated one hour’s drive from Palm Springs, 30 miles to the south of Indio, California on Highway 111. Its distance from Los Angeles and San Diego is approximately three hours driving time. The most recognizable natural phenomenon of Imperial and Riverside counties, it is surrounded by a rural area comprised of predominantly migrant farm workers and located in the southern Colorado desert area known as the Salton Trough, or Salton Sink. Despite being a natural occurrence filling and emptying intermittingly throughout history, the current presence of this large inland sea surrounded by sand was created accidentally in the early 20th century. First formed around 700 CE, the original and much larger version of the great inland lake was called Lake Cahuilla, connected to the Sea of Cortez. By the time the first Europeans arrived in the 16th century, the basin was completely dry as Don Juan Bautista led the first party across the basin’s expanse. The “accidental” creation of the lake’s modern version was a product of the rising Colorado that destroyed a crucial section of the canal system designed to help farmers. Millions of gallons of water were forced into the lowland area. Beyond the one breach, the entire volume of the river flowed into the Salton lowlands for nearly two years before engineers finally stopped it.Show book
Humans are the most intelligent beings this planet has ever produced. But how is it that we find ourselves faced with an existential crisis that threatens to overwhelm us? Leading archaeogeneticist Johannes Krause and journalist Thomas Trappe investigate what DNA can tell us about how we got where we are and what our future might be. They show how the first humans were defeated again and again and suffered fatal setbacks, and how Homo sapiens succeeded in conquering continents, overcoming natural borders, and bringing other species under its control. But the genetic blueprint that enabled us to get to the place where we are today had one flaw: it didn't factor in planetary boundaries. Now that we are approaching those boundaries for the first time after millions of years of evolution, an urgent question arises: can we learn to live within the planetary limits, or are we doomed by our DNA to continue to expand, consume, and absorb the resources around us to the point of exhaustion, consigning ourselves and other species to extinction? While the looming climate crisis does not augur well for humanity's capacity to adapt to the new situation in which it finds itself, we are not at the mercy of our DNA—or at least we don't have to be. But can we harness the lessons of the past to survive the present?Show book
