Life on Earth evolved once - this means that all biological systems on our planet are rooted in the same fundamental framework. This framework is extremely complex and we have yet to fully understand the processes inside each living cell. One way of understanding complex systems is to break them down into simpler parts. This is the principle of engineering the synthetic cell: to use our current knowledge of biology for building a living cell with the least amount of parts and complexity. Synthetic cells can be used to teach us about the basic principles of life and evolution, and they hold promise for a range of applications including biomaterials and drug development. Dr. Kate Adamala narrates an introduction to this exciting field.
