Usually when you think of evolution or natural selection, you think of survival of the fittest. But sometimes, the resulting traits of evolution aren’t the most efficient solutions to the problems at hand. With the bar set to “good...

Explore the concept of biological evolution with the Amoeba Sisters! This video mentions a few misconceptions about biological evolution before providing a general definition. Then this video provides a description of four different...

Humanity has changed a lot since the days of our ancestral species, and we have continued evolution to look forward to as well.

Medical ethicist Harvey Fineberg shows us three paths forward for the ever-evolving human species: to stop evolving completely, to evolve naturally -- or to control the next steps of human evolution, using genetic modification, to make...

Paul Andersen describes pieces of evidence that Charles Darwin used to support the idea of evolution and his process of natural selection. He begins with the following evidence use in the Origin of Species; artificial selection,...

Could humans ever evolve to have wings? Why don’t fish have propellers? Why don’t tigers have wheels? Why don’t zebras have laser turrets? These might all seem like stupid questions (and maybe they are!) but they can teach us a lot about...

We all know Charles Darwin's theory of evolution, right? Natural selection? But what about his lesser-know theory of evolution: sexual selection. Let’s talk about how animals like peacocks, whose eye-catching physical traits make them...

In the past 3,000 years, many populations have evolved genetic adaptations to their local environments. People in Siberia and the high arctic are uniquely adapted to survive extreme cold. The Bajau people can dive 70 meters and stay...

Hank explains where that over-simplified image of evolution comes from and what it is actually supposed to mean.

Hank gets real with us in a discussion of evolution - it's a thing, not a debate. Gene distribution changes over time, across successive generations, to give rise to diversity at every level of biological organization.

Hank brings you the facts, as they are understood by scientists today, about the evolution of humans from our humble primate ancestors. On the way to becoming Homo sapiens, game-changing evolutionary breakthroughs led to the development...

Evolution vs Natural Selection

Psychologist Jonathan Haidt asks a simple, but difficult question: why do we search for self-transcendence? Why do we attempt to lose ourselves? In a tour through the science of evolution by group selection, he proposes a provocative...

Natural selection can lead to some pretty amazing adaptations, but sometimes the resulting traits aren’t the most efficient solutions to the problems at hand. With the bar set to “good enough,” here are some features that arose from...

What will become of humanity after spend a few hundred years on Mars? What will happen after a few thousand? Evolution has, and still is, shaping humanity in rather drastic ways. How long will humans stop being human and become Martian?

Paul Andersen teams up with Keith Hughes to explain why teaching evolution is not optional for high school biology teachers.

Do you like drinking milk or chatting with your friends? Well, you can enjoy those because of the evolution happened over the past million years, and we are still evolving. Let's find out what will we be like in the future with us!

Evolution vs Natural Selection

Evolution is inherited change in a population of organisms over time resulting in appearance of new forms, under the influence of pressure from the environment. Note changes are in populations not individual...

Learn about the evolution of a star and how stars are created and develop with this Stellar Evolution video by KLT!

This video introduces the theory of evolution by natural selection and explores evidence for human evolution, specifically through fossils and stone tools. The speaker explains that evolution is the gradual change in characteristics over...

Evolution “is the net change in organisms or a population over the span of many generations.” This change in organisms or populations happens through DNA mutations and reconbination and is passed down to the next generation through...

Charles Darwin’s Theory of Evolution is perhaps the most famous, and certainly the most controversial, scientific theory ever developed. First published in 1859 in a book titled, On the Origin of Species by Means of Natural Selection, or...
