How People Have Evolved to Live in the Clouds
High elevations can be a problem for humans. Since the air is thinner, you get less oxygen with every breath, leading to all kinds of negative side effects. But there are millions of people around the world who spend their whole lives at...

LS3B - Variation of Traits
In this video Paul Andersen explains how variation is created in a population over time. Variation in offspring is caused by genetic recombination, mutations and environmental effects. Parental DNA is recombined using the process of...

TED-ED: How bones make blood - Melody Smith
Bones might seem rock-solid, but they’re actually quite porous inside. Most of the large bones of your skeleton have a hollow core filled with soft bone marrow. Marrow's most essential elements are blood stem cells and for patients with...

Mutations
Paul Andersen describes the major mutations found in the living world. He starts with an analogy comparing the information in DNA with the information in a recipe. Changes in the DNA can result in changes to the protein, like changes in...

TED-Ed: Where do genes come from? - Carl Zimmer
When life emerged on Earth about 4 billion years ago, the earliest microbes had a set of basic genes that succeeded in keeping them alive. In the age of humans and other large organisms, there are a lot more genes to go around. Where did...

What is Evolution: A REALLY SIMPLE and Brief Explanation
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...

What are Mutations and what are the different types of Mutations?
A mutation is a random change in the DNA. Mutations can be neutral, which means it does not cause a change in a trait of the organism, or it could cause a beneficial or a harmful mutation. There are a few different types of mutations -...
