How Did Complex Life Evolve?
According to evolutionary biologist Jordi Bascompte, the transition from simple prokaryotes to eukaryotic cells was likely the most important step in the history of life on Earth.

Fungi, plants, animals and humans are made of eukaryotic cells. These cells evolved at a late stage in the evolution of life. Evolutionary biologist Jordi Bascompte and his team have unraveled how the first complex life forms arose and were able to evolve.
