    On average, humans of European descent have between 2-4% Neanderthal DNA that has been passed down over the last (estimated) 65,000 years which is when it is thought that these two species interbred. Researchers have established a correlation between certain types and combinations of this DNA with smoking and mood. When these types and strengths of DNA are present, an individual has a statistically greater chance of smoking and/or having problems with mood.

Serotonin Production: Researchers at the Weizmann Institute of Science in Israel have succeeded in identifying traces of a microRNA molecule (miR135) that acts on serotonin producing nerve cells.

When this idea was tested on humans, subjects known to suffer from depression had unusually low miR135 levels. The researchers are confident this will lead to the development of a blood test for depression.
