A group of researchers from Michigan State University (USA) has carried out a patient experiment lasting no less than 25 years, during which more than 50,000 generations of Escherichia coli bacteria have been analyzed.

In other words: the experiment has made it possible to 'see' directly the famous evolution by small changes that Darwin spoke of in the 19th century.
