One Health through genomic studies

Over the past two months, two studies that say a lot about the linkages between different compartments in our world have been published in the scientific journal Science. They both investigated a large number of genomes. In one case the authors built a genealogical tree using thousands of human genomes from all over the world in an attempt to map all human genetic relationships. The endeavor resulted in the world’s largest family tree. The research has not only given an interesting view of humanity’s history but also showed how, if we go back in time enough, everyone is connected. Going back in time first one can see how one person’s tree merges with someone else’s, going a bit further into the past clans start merging as well, then clades, to finally end up with one tree representing all of humanity.  

In the second case, the authors investigated thousands of white clovers’ genomes across 160 cities comparing them to their rural counterparts. The study suggests that urban flora has adapted to living in these human-made environments. In other words, that human factors are also a driver in the evolution of life.  

The studies underline the links between humans and between humans and the natural environment of which we are a part. Therefore, they emphasize the connections and the need to be aware of this. We are part of a complex system that is more than just the sum of its parts.
