Evolution

Neanderthals (Homo neanderthalensis) and humans (Homo sapiens) are two distinct species within the genus Homo. Neanderthals lived in Eurasia until about 40,000 years ago, alongside ancient humans.

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?

Let's assume that long ago Homo sapiens communicated by grunting at one another. How and when did all those grunting sounds evolve into a verb tenses, clauses and proper nouns?

Imagine a time in Earth's far-flung past when organisms didn't swim through the oceans or populate the lands. Even the mighty dinosaurs hadn't arisen. Will the planet ever return to that lifeless state?

When a basketball superstar makes a 3-pointer, the multimillion-dollar paychecks go into his or her bank account. But why don't his or her parents get the glory? After all, didn't they provide the DNA that allowed for such incredible success?

We don't admit to breaking up with someone because of his looks, or that we've read our boss's private e-mails. We answer "fine" when someone asks how we are, even if we're not fine at all. Why is polite society all about the big fib?

A mass extinction on Earth is long overdue, according to population ecologists. Find out what Earth's fossil record may be telling us about our future.

We can see dinosaur and plant fossils at just about any natural museum. What exactly are fossils, though, and how do they form?

By Austin Henderson

Natural selection is the idea that organisms that are best suited to survive pass their traits down. Is it true that only the strong survive?

Where did humanity begin, and how did we get to where we are now? Did we really all begin in Africa? What made us leave?

Polar bears evolved to blend in with the terrain so they could hunt better. What causes one group of animals to split off from the rest of the species and develop new genetic traits?

By Josh Clark

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.

Since Charles Darwin published the theory of evolution by means of natural selection, myths and misinterpretations have eroded public understanding of his ideas. Ready to take another look at one of the related questions that just won't die?

Depending on whom and when you ask, everything from same-sex smooching to punk music portends the end of Western civilization. Do any of these cultural commentators have a case?

A new global report says 1 million species are at risk of extinction - the greatest number in human history.

By Jonathan Strickland

Evolution is fascinating because it attempts to answer one of the most basic human questions: Where did life, and human beings, come from? The theory of evolution proposes that life and humans arose through a natural process.

By Marshall Brain

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?

Long before sonnets, sestinas and short stories were historical accounts of kings carved onto clay tablets. Who were the first writers and what did they scribble?

By Charles W. Bryant

You'd think being able to smell drinkable water would be an evolutionary advantage. But we can only smell things that suggest potable water. Why is that?

Neanderthals may be long gone, but their genetic footprint lives on - in us.

By Robert Lamb

Humans can certainly claim some of these, but sloths, giraffes and pandas wanted a piece of the action, too. The hyena adaptation, however, may just blow your mind.

Organisms not related to each other can develop similar physical attributes without even exchanging notes.
