Evolution vs. Natural Selection

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...

Charles Darwin studied many species, but he also hindered their continued study by eating his specimens. Like many sailors, he enjoyed the taste of the Galapagos tortoise so much for many years that no ship made it all the way back to...

Scientists believe red hair and pale skin evolved in northern Europe because it helped humans synthesize vitamin D easier than those with more melanin in their skin. Viewers explore many interesting facets of evolution in a...

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...

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...

Selective breeding has resulted in some novel and beautiful or useful dogs over the years. Using the American Foxhound as an example, genetics learners find out how and why they came about. Then, in small groups, they select breeds to...

How does something remain the same in order to change? The video discusses homeostatic evolution from both the continuity and changing perspectives. An analysis of the excretory system in flatworms, earthworms, and vertebrates shows...

Humans share about 50% of their genes with a banana. In the video, scholars analyze the scientific evidence for evolution. The instructor spends time discussing Darwin and biogeography, fossils, and homologous structures. Scholars then...

Clear up any confusion related to natural selection and evolution. This straight forward clip explains the differences between natural selection and evolution and sheds light on misconceptions Charles Darwin had about the process of...
