The man who bottled evolution

Evolution is a slow process that cannot be seen in real time. So evidences of evolution are always searched backward in time, using the fossil record, genetics or biochemistry of living things today, but it cannot be studied forward (we never know how species are going to change).

Plates with bacteria culture

In 1988, at the Michigan State University, an experiment started with bacteria. Richard Lenski and his research group began to grow 12 populations of Escherichia coli and by reproducing and caring them day and night they have completed over 58.000 generations(equivalent to 1 million years in humans).

The conclusion in this experiment, which has been operating for over 25 years, is evolution never stops, even when the conditions of life do not change.
