How are Fibonacci numbers expressed in nature?
Is there a magic equation to the universe? Probably not. But thanks to one man's obsession with rabbits, we have a sequence of numbers that reflect various patterns found in nature.
How Biomimicry Works
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 can two seemingly unrelated species that live in isolation from each other evolve into identical forms?
When Australia became separated from the other continents, its species evolved in isolation. And yet, some of the Australian animals evolved in exactly the same way as the other animals in the world. How?
How Extinction Works
Whether they're big or small, extinctions change the world. And while extinctions themselves are all about change, the study of extinction is all about uncertainty. Anything that lives can become extinct, but how do scientists know when it happens?
How Human Migration Works
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?
How Natural Selection Works
If nature is red in tooth and claw, then "survival of the fittest" sounds like a fight to the death. Natural selection is what drives evolution. Is it true that only the strong survive?
How Symbiosis Works
One kind of flatworm doesn't have a working mouth, because the algae that lives inside of it makes food for the worm. Symbiosis is crucial to the survival of many species. In fact, you're a symbiote yourself.
Will we soon be extinct?
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.
100 Greatest Discoveries: Evolution (Video)
See how the fossil record changes our view of what it means to be "human." Learn more about evolution in this video from Discovery.
A New Look at Evolution (Video)
Could corn be smarter than humans? It sounds absurd at first, but watch this video to see our world from a plants-eye view. What is and how does evolution really work? Video courtesy of TED.
Future of Human Civilization (Video)
Scientist Michio Kaku speculates on the future of human civilization and the potential for self-destruction or progress.
What is the fibonacci sequence? (Video)
Leonardo Da Vinci explored the idea of the golden mean which is also found in one of the most famous number sequences known as the Fibonacci Sequence. Learn more about this sequence on Discovery Channel's "Assignment Discovery."
Darwin's "Origin of Species" (Video)
On Discovery Channel's "Assignment Discovery," learn about Charles Darwin and the writing of his historic book, "Origin of Species."
Origin of Life (Video)
Could there be life elsewhere in the universe? Learn how researchers can speculate about other life based on their research of life on Earth in this research video from Georgia Tech.
How Evolution Works
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.
How Creationism Works
The public debate between Christian creationism and evolution has heated up once again in the United States. Learn about the different forms of Christian creationism and find out what's fueling the controversy.
How Intelligent Design Works
How does intelligent design explain the origins of life? Does it fit the criteria of a scientific theory, or is it religious dogma in a scientific wrapper? In this article, we'll examine intelligent design and the controversy it has generated.
