Paul Andersen explains how natural selection is a major mechanism in evolution. The video begins with a discussion of Charles Darwin and the details of natural selection. The data of the peppered moth during the industrial revolution...

Hank guides us through the process of natural selection, the key mechanism of evolution.

There are lots of ways that evolution happens, and natural selection is just one of them. In this episode of Crash Course Biology, we’ll find out how this process works and shapes traits in all living things —from ginkgo trees to howler...

This video explains the theory of evolution by natural selection as proposed by Charles Darwin and published in his book on the Origin of Species in 1859. It describes how all species of living things have evolved from simple life forms...

Paul Andersen details examples of natural selection in the world. He starts by explaining how changes in global temperatures are causing plants to adapt. He explains how mutations cause changes in phenotype which give organisms varying...

Explore all the terms around evolution, including 'natural selection', 'variation', and 'survival of the fittest'. And see how Darwins came up with the theory of evolution despite not even knowing what DNA or mutation were.

The video “Selecting a Change” introduces the concepts of natural and artificial selection and discusses examples of each.

This video discusses the concept of variation in a population and the factors that cause it, including genetic inheritance, mutations, and environmental factors. The video then goes on to explain the theory of evolution and how natural...

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...

Hank talks about population genetics, which helps to explain the evolution of populations over time by combing the principles of Mendel and Darwin, and by means of the Hardy-Weinberg equation.

SciShow welcomes back Diana Six to talk to us about current news on the Mountain Pine Beetle Outbreak. Then, Jessi Knudsen Castañeda stops by and brings a familiar friend whose anatomy may help scientists develop better hypodermic needles.
