When it comes to the topic of evolution Charles Darwin is "the man." In 1859, his book, On the Origin of Species provided compelling evidence that transformed the theory of evolution into widely accepted fact.

Evolution is the process by which an organism changes over time to better adapt to its environment. This theory includes the idea of coevolution — where two or more species evolve together for their mutual benefit.

"The 'tree of life' that we have believed in as the picture of evolutionary history, ever since Darwin, is not entirely wrong but drastically incomplete and too simple. Tree branches always diverge, and it turns out evolutionary lineages diverge and converge. So limbs grow together and there are channels that have moved from one branch to another. The premise of my book is that the tree of life is not strictly a tree—it is a web, it’s a network, it’s something for which we don’t have a visual metaphor. It’s a tangled tree and the history of life is radically different from what we thought we knew 45-50 years ago. . ." -- David Quammen

08/07/2015 - In this episode, a question that haunted Charles Darwin: if natural selection boils down to survival of the fittest, how do you explain why one creature might stick its neck out for another? Is altruism an aberration, or just an elaborate guise for sneaky self-interest? Do we really live in a selfish, dog-eat-dog world? Or has evolution carved out a hidden code that rewards genuine cooperation?
