Guided Human Evolution

            The Merriam-Webster dictionary defines evolution as the following: “the process by which new species or populations of living things develop from preexisting forms through successive generations.” When we think of evolution, we think of it as a natural process that gives us insight into the history of where we came from and how certain traits came into being within our species. However, it is about more than our history; it is about where our species is headed. While some may argue that by advancing our species using technology rather than allowing it to occur “naturally” we are somehow committing some evil or, perhaps, “playing god.” However, we have been taking matters into our own hands regarding our health and well-being for centuries. Any form of medicine could be considered as “playing god” because we are attempting to prolong our lives. Illnesses which were once considered life-threatening can now be defeated with the creation of antibiotics and vaccinations. As a result, our species now has longer lifespans. While this affects us long-term, it is not necessarily evolution as it is not something which can be passed onto future generations. It is simply a matter of sustaining our own lives. However, with the rapid advancement of genetic modifications and medical technology, we have begun to see the rapid approach of possible human evolution. We are beginning to see success regarding gene editing, for example. This guided version of evolution is sometimes referred to as neo-evolution. However, us being able to manipulate our genes, possibly as traits that continue to get passed on for all the following generations, requires a discussion of ethics and authority. Who should be able to affect the evolution of our species and for what purposes can it be acceptable to do so?


The following quiz questions will be based on the video embedded below.

  8. Neo-evolution as described by Fineberg is not simply natural, but what?
  9. The Human Genome project started in what year?
  10. What two scientists independently developed techniques to encourage the natural process of evolution to work faster and to lead to desirable proteins in a more efficient way?
  11. What research led to Shinya Yamanaka receiving the Laskar Prize?
  12. According to Fineberg, with Neo-evolution, we could take a process that might take 100,000 years and compress it down to about how long?
Discussion questions:
  1. Who should decide the direction of human evolution?
  2. For what purposes should we guide evolution?
  3. What do you think are the social and/or economical repercussions of guiding evolution?

  1. "Who should decide the direction of human evolution?" If we've posed the question at all, we've already begun to "decide" that our selective intentions are relevant to evolutionary design. So, the short but possibly unhelpful answer is: we should decide, we who are drawn to the question and thus implicitly recognize it's not all up to blind nature any more. But deciding, at this early stage, SHOULD mean deiberation, discussing, considering, and proceeding with extreme precaution. I fear that may not be how it goes. But if we can make even a small contribution to the process, I hope we'll guide evolution in the direction of ever-greater social empathy and mutual support. Every small decision undertaken in that light, in theory, will contribute to nature's design of a more cooperative and less belligerent human species. Can we afford NOT to try and guide our evolution in that dieretion?
