About the origin of Life on Earth
This talk is about fascinating facts and interesting theories about the puzzling origin of life on Earth. I will start with an overview how Earth geologically developed and trace the evolution of life on Earth. We will look into a few curious turns that Nature took along the way. Then, I will focus on the origin of life, the first reproductive biological systems. A puzzling fact is that life on Earth developed extremely quickly, although the step from non-living matter to living systems appears to be very improbable. We will look into potential solutions to this conundrum with surprising implications.

Neuronal cell nuclei are shown in yellow for the granule neurons in the dentate gyrus region of the hippocampus. Blood vessels are shown in red. By changing the X-ray optical magnification in the multi-scale recordings, one can zoom into regions-of-interest (red ovals). In these scans the resolution is high enough to resolve sub-structures of the nucleus, associated with different DNA packing regimes.
