"Synthetic" Biology and Evolution by Symbiosis
I like using synthetic to mean “working together”, in “real” synthetic biology as bringing together (synthesizing) a lot of components from different living things in order to create a unique whole, and in “natural” biology in terms of how every living thing must live together with others in communities made up of complex interdependent relationships. I’ve recently been reading a lot of Lynn Margulis’s work on Serial Endosymbiotic Theory (SET): how eukaryotic cells developed through multiple endosymbiotic events between different species of bacteria, with early cooperative relationships leading to intricate co-dependence and entire new domains of life. I love this picture from her article “Serial endosymbiotic theory and composite individuality” for its complexity and for highlighting how deeply connected all life on earth is. We are all synthetic communities.
