Could a population stay the exact same over time with no change in allele frequencies? The video explains the Hardy-Weinberg equilibrium theorem and the assumptions it requires. It discusses mutation, migration, gene flow, genetic drift,...

Peacocks, when fanning their feathers to attract females, shake the feathers, creating an inaudible sound for humans but one that female hens can hear, even from far away. In the video, scholars explore evolution by analyzing...

Humans, through artificial selection, created a dog that is hypoallergenic, loves water, is good with kids, very smart, and comes in a variety of colors — a labradoodle. Through the analysis of dog breeds, class members explore...

Learn about driving forces of evolution other than natural selection. Group selection and artificial selection are just a few of these forms of 'Alternative Selection.' [4:34]

This video from Nature offers a description of desirable traits in beef and dairy cattle. [2:55]

How humans have shaped plants and animals through artificial selection and domestication. [4:10]

In this video segment from Nature, learn about six different breeds of cattle. [6:46]

This lesson will explain how artificial selection can affect the species in a given area. It is 1 of 4 in the series titled "Artificial Selection."

Paul Andersen details the first 7 of 13 labs in the AP Biology Curriculum. The following topics are all covered: Artificial Selection, Hardy-Weinberg Equilibrium, Comparing DNA using BLAST, Diffusion and Osmosis, Photosynthesis,...

Paul Andersen explains the importance of selection in biology. Artificial selection occurs when humans choose traits that will be selected for or against. This has created the variety of domesticated animals and crops. He then describes...

This lesson will explain how artificial selection can affect the species in a given area. It is 2 of 4 in the series titled "Artificial Selection." [2:21]

Paul Andersen describes pieces of evidence that Charles Darwin used to support the idea of evolution and his process of natural selection. He begins with the following evidence use in the Origin of Species; artificial selection,...
