Myths and misconceptions about evolution
Myths and misconceptions about evolution
Let’s Begin…
How does evolution really work? Actually, not how some of our common evolutionary metaphors would have us believe. For instance, it's species, not individual organisms, that adapt to produce evolution, and genes don't "want" to be passed on -- a gene can't want anything at all! Alex Gendler sets the record straight on the finer points of evolution.

What is Natural Selection?
What is Natural Selection?
Natural Selection is one of the main concepts found within the theory of evolution. It was discovered by Charles Darwin and Alfred Russel Wallace though Darwin championed the idea in his book "On the Origin of Species".
Natural selection can be defined as the process by which random evolutionary changes are selected for by nature in a consistent, orderly, non-random way.
When coupled with descent with modification, Natural Selection can cause a population to evolve for fitness within a given environment over multiple generations.
Natural Selection is an observable fact. By carefully observing populations of living things with short life cycles you can actually watch it happen.
Want to learn more? Check out our notes for this video. Included are links to three examples of natural selection witnessed by researchers. There are many more as well.

This video also uncovers the relationship of natural selection and antibiotic resistance in bacteria and emphasizes biological fitness. This video is focused on natural selection. When we briefly mention evolution as 'change over time', this IS a bit too much of a simplification. We eventually hope to make a video specifically on evolution itself.

Where Did Life Come From? (feat. PBS Space Time and Eons!)
The origin of life is one of the most important mysteries in all of science. When did life begin? How did life first evolve from chemistry? Where did life get started? In some primordial soup or somewhere else? Let’s journey back to the origin of life, as best as we know it, from the RNA world do the last universal common ancestor of everything alive today.

Theory of Evolution: How did Darwin come up with it?
160 years ago, the British naturalist published his famous book “On the origin of species”. His theory radically transformed Biology, offering a new explanation of the ancestry and evolution of living beings.
