Should Scientists Play God?

The quote below is from Should Scientists Play God? MIT Biological Engineer Says YES! by Emily Reeves

That’s the topic raised in a recent TEDx talk by Dr. Erika DeBenedictis, an MIT doctoral graduate in biological engineering. Before you read any further, I encourage you to watch her 11-minute TEDx talk:

Dr. DeBenedictis takes a bold approach in the video, stating that scientists should play God. “Biology is imperfect,” she says. “Let’s make it better.” Her position, in short, is that biology is not well-designed and that, given the opportunity, scientists can and should finally “intelligently design” life.

She’s a likeable, enthusiastic, young scientist whose motivation for “playing God” seems to come from ambitious goals to change the world for good. As a recent PhD graduate myself, I identify with much of what DeBenedictis is trying to do and am equally enthusiastic about advancing applications of biological research.

And yet, I do not think that scientists should “play God.” As I hope to demonstrate in a series of posts, there is overwhelming evidence to suggest that biology is, in fact, incredibly well-designed. There is much we still do not know about biology, and labeling something as “poor design” often occurs when biological mechanisms are misunderstood (I will provide historical examples). Setting goals of making biology “better” without first undertaking a deep investigation into the biology could be very unwise. So how then should biological engineering move forward? By focusing on mimicking the design in biology we can improve human engineering and learn how to exploit nature safely for our unique purposes. Additionally, by recognizing the good design in biology when random mutation has corrupted it, we can also mobilize human intervention to restore that design.

Ever Heard of a Non Sequitur?

Here’s one. Dr. DeBenedictis makes the following statement.

Organisms are absolutely the most sophisticated machines we know of and they came about after 4 billion years of random chance.

Do you see it? The second statement (“4 billion years of random chance”) is hard to reconcile with, and hardly follows from, the first (“Organisms are absolutely the most sophisticated machines we know of”).

Commitment to evolutionary theory creates this sort of confusion in the natural sciences. Scientists observe “the most sophisticated machines we know of” in the natural world, with complexity and efficiency exceeding even the best examples of human engineering. But we are told to reconcile our observations within the consensus view that biology is the result of “4 billion years of random chance.” My perception is that DeBenedictis, like many others, has ignored the cognitive dissonance that commitment to “random chance” creates and has instead tried to rationalize theproblem by looking for “poor design” in biology.

It’s Not Her Fault

This is what the academy teaches. Mutation (directed or random) can modify existing information when a strong “selective pressure” is present. This was nicely demonstrated by Dr. DeBenedictis with a directed evolution experiment she conducted using her intelligently designed Phage-and-Robotics-Assisted Near-Continuous Evolution (PRANCE) platform. But the creative power of mutation and selection in biology has been overestimated and few seem willing to acknowledge the limits. Despite little acknowledgement, the discipline of engineering (including the design of PRANCE) depends on intelligent design and foresight for all novel large scale innovations, thus testifying that no sophisticated machines outside of biology have an origin aside from intelligent design. Given that biology contains the “most sophisticated machines we know of,” a consistent explanation derived from observations of human engineering would be that biological machines are also the result of intelligent design.

Humans are born to take dominion, and they are going to do it – in a lawful or lawless fashion.

Either earning our stripes, day after day, in humble service… or impatiently grabbing power, serving nothing and nobody except ourselves.
