University of Utah: Learn. Genetics: Recipe for Natural Selection

The evidence for natural selection is presented as a random variation of a characteristic allowing a particular strain of organism to survive with a higher probability of successful reproduction. Population change over a short period is...

What evidence is there for natural selection? Science sleuths examine the facts using an animated Fuse School video as part of the Evolution playlist. Content includes fossil records, physical similarities, and differences in...

The peppered moth is featured in a video about natural selection. The narrator tells the story of Darwin's theory and then moves on to the principles behind natural selection and the different ways it works. Concepts covered include...

Sickle cell disease only occurs when both parents contribute the trait, and mostly in those of African descent. Where did it come from? How did it evolve? Tony Allison, a molecular biologist, noticed a connection between sickle cell and...

Explore natural selection by controlling the environment and causing mutations in bunnies.

Explains how the eyes of very diverse species have a common genetic ancestry.

Practice the steps of cloning in this interactive animation. Using what you know about somatic cell nuclear transfer, your mission is to create a genetically identical clone of Mimi, a brown female mouse. You'll answer a few questions at...

Examine exactly what is meant by natural selection, as well as how it works in nature and through the assistance of humans. Presented with fun graphics and simple narration, the complex topic of natural selection is clearly explained in...

Between 1968 and 2002, the total number of peppered moths decreased by almost two thirds, although scientists do now know why. In the 10th video of the series, the instructor defines evolution as any changes to a gene pool. Scholars then...

Viewers explore real-world examples of both evolution and natural selection as the instructor discusses changes to the environment, mutations causing changes in phenotypes and changing the fitness in organisms, and how humans are...
