Au revoir, Pluto! In this newly revised, bestselling backlist title, beginning readers and budding astronomers are launched on a wild trip to visit the now eight planets in our solar system (per the International Astronomical Union’s 2006 decision to downgrade Pluto from a planet to a dwarf planet), along with the Cat in the Hat, Thing One, Thing Two, Dick, and Sally. It’s a reading adventure that’s out of this world!
Nearly 4,000 cities on our planet today have populations of 100,000 people or more. We know their names, locations, and approximate populations from maps and other data sources, but there is little comparable knowledge about all these cities, and none that can be described as rigorously scientific.
This text is designed for students and anyone else with an interest in the history of life on our planet. The author describes the biological evolution of Earth’s organisms, and reconstructs their adaptations to the life they led, and the ecology and environment in which they functioned. On the grand scale, Earth is a constantly changing planet, continually presenting organisms with challenges. Changing geography, climate, atmosphere, oceanic and land environments set a stage in which organisms interact with their environments and one another, with evolutionary change an inevitable result.
Last Ape Standing: The Seven-Million-Year Story of How and Why We Survived
Over the past 180 years scientists have sifted through evidence that at least twenty-seven human species have evolved on planet Earth. And as you may have noticed, twenty-six of them are no longer with us, done in by their environment, predators, disease, or the unfortunate shortcomings of their DNA. What enabled us to survive when so many other human species were shown the evolutionary door?
