In David Quamann’s delicious book, The Tangled Tree, he expertly unravels the story of horizontal gene transfer, our rather our current understanding of it. The ability of genetic code to migrate between species, even between kingdoms, throws our understanding of evolution. It also calls into question our understanding of the individual, at the level of organisms to that of species. Our bodies, made of 10% human cells and 90% of bacteria, viruses, etc., are colonies as much as our towns are. To reference David Bohm, our cells are in a constant dialogue with each other, creating something far different than their original genetic makeup would predict. We have mapped our genetic code and most of the world, seen it with our eyes, our microscopes, or our satellites, and yet, there is still so much we don’t know, still so much terra incognita. It seems that while we have amassed the technology to see a cell, a body, a forest, or a mountain range, we haven’t yet figured out how to see the dialogue between - this is our terra incognita.
