Author Annalee Newitz (Gawker Media's Gizmodo editor-in-chief) talks to us about Earth's 5 mass extinctions, as well as the possibility that we live in one right now.

When peering thousands of years into the future, there are certain things we can count on -- evolution, extinction, plate tectonics, climate change and, quite possibly, the eruption of a supervolcano. What else does the Earth's far future hold?

Batesian mimicry is an evolutionary strategy used by vulnerable species to look like a dangerous species so predators will leave them alone. But it only works under the right circumstances.

As the human population soars, our ability to feed all those hungry mouths can't keep pace. How did an English economist by the name of Thomas Malthus wind up thinking about this very issue in the 19th century, and what's his connection to Darwin?

Every species on Earth, from the majestic humpback whale to the bacteria happily living in your gut, has a special role to play within a defined ecosystem. Can organisms ever trade their existing niches for new ones?

According to DNA research, we may all have a common ancestor, an African woman who lived thousands of years ago. How did scientists reach this conclusion? Is it even possible?

Have you ever done something for someone else just because it was a nice thing to do? Do people perform unselfish acts because it feels good or is it just something society wants us to do?

If wisdom teeth are so wise, why do they keep sprouting in the gums of people who don't need them anymore? Should a lack of wisdom teeth give you bragging rights as a highly evolved human?

The Galapagos Islands may have played a grand role in Darwin's theory of evolution, but they're notable for more than their finches. What strange species populate these remote islands?

Everyone knows that humans require food, water and shelter, but what about knowledge? It turns out that we have an innate, unquenchable need to seek out new things and new stimuli. Aren’t you curious?

A gulf of difference may separate our human world of empires, science and spirituality from the animal wilds of the other great apes. But the genetic differences are pretty meager.

Everything has to start somewhere, including us humans. But where? Was it Africa, or were there multiple ground zeros for humanity's explosive growth and eventual world domination?

If you swim like a fish or run like a cheetah, you may understand biomimicry better than you realize. The practice involves imitating models in nature to improve technology and design.

How did life on Earth begin? Theories abound, but one popular one posits that it started spontaneously from primordial ooze on our planet, while another holds that it literally came from outer space. Who's right?
