Examples of directly observed evolutionary changes

Anolis Lizards

150 years after Charles Darwin (and others) first proposed the theory of evolution due to natural selection, many people still struggle to accept and understand the theory. One frequently observed claim is that evolutionary change cannot be observed.

The website phylointelligence.com has a great list (with scientific references) of examples of evolutionary changes that have been directly observed by scientists. A great resource for science teachers (and everyone interested in evolution).

See the list of observed evolutionary changes here. The examples also include the occurance of human lactase persistence which I used as a case study in my PhD (see PDF here).
