132 | Michael Levin on Growth, Form, Information, and the Self

132 | Michael Levin on Growth, Form, Information, and the Self

As a semi-outsider, it's fun for me to watch as a new era dawns in biology: one that adds ideas from physics, big data, computer science, and information theory to the usual biological toolkit. One of the big areas of study in this burgeoning field is the relationship between the basic bioinformatic building blocks (genes and proteins) to the macroscopic organism that eventually results. That relationship is not a simple one, as we're discovering. Standard metaphors notwithstanding, an organism is not a machine based on genetic blueprints. I talk with biologist and information scientist Michael Levin about how information and physical constraints come together to make organisms and selves.

It's fun to spend time thinking about how other people should behave, but fortunately we also have an inner voice that keeps offering opinions about how we should behave ourselves: our conscience. Whe...
