Evolutionary logistics

How the first molecules could have met up

More than 3 billion years ago, the first forms of life on earth came into existence. The first complex chemical structures developed and formed the basis for the later protozoa. According to a scientific theory, this first step to life presumably took place in the oceans. But to build up complex structures, the dissolved and low- concentrated reactants had to meet each other.

Now the LMU physicists Christoph Mast and Prof. Dieter Braun – both members of the NIM Cluster of Excellence - simulated the principle of these matching molecules in the lab. The scientists were thereby able to re-concentrate and also replicate dissolved genetic material purely by means of a temperature gradient.
