Humanity is now awakening to the reality that Earth is comprised of a living system, one that we ultimately depend upon for our survival. http://earthasweknewit.org/pages/the-gaia-hypothesis
Extinction events can be seen as a normal part of evolution's cycle of growth and decay. Here we examine megafauna and hominid species that were wiped out as Homo sapiens expanded their reach. http://earthasweknewit.org/pages/evolution-extinction

A deep history of how our planet gave birth to our species, how we awoke to our true nature, and how we in turn have re-shaped Earth itself. This is the creation story of our strange new planet. http://earthasweknewit.org

Examining the tension between Science & Religion, and how our definition of the word "God" can evolve so as to encompass both. http://earthasweknewit.org/pages/redefining-god
With our hominid ancestors new capacity for language comes the first attempts to understand the world, the development of stone-age tools, and a mythology to describe what's beyond the mind's reach. http://earthasweknewit.org/pages/stone-age
With the development of larger brains & the capacity for language, our ancestors rose from their place among the animals, to occupy a new status upon the planet. http://earthasweknewit.org/pages/eden
The planet's climate has evolved a self-regulating system that for millions of years has kept it within cyclical norms. http://earthasweknewit.org/pages/climatic-equilibrium
The natural law gave rise to Earth's diversity of life, through the evolutionary shaping mechanisms of genetic variation & natural selection. http://earthasweknewit.org/pages/natural-selection
Within the Neolithic Revolution humans adopted an agrarian way of life. Instead of reacting to our environment, we began to actively shape it, using artificial selection to mold the traits of species to serve our needs. http://earthasweknewit.org/pages/neolithic-revolution
We share much of our genetic code with evolutionary cousins, much of which evolved hundreds of millions of years ago. This complex biological system allows for some genetic mutation, making it adaptive to change, morphing throughout time. http://earthasweknewit.org/pages/our-genetic-formula
Photosynthetic organisms transformed Earth's atmosphere into the oxygen rich air we breathe today, laying the foundations for sentient life. http://earthasweknewit.org/pages/oxygen-atmosphere
