In “real time” they show the function of an enhancer in switching a gene from off to on.
Complexity (such as we see in a pile of autumn leaves) can arise spontaneously from unguided natural processes, but complex specified information cannot.

After going through the appearance of hand-wringing, I wouldn’t expect much of a problem if scientists said they really wanted to proceed.
Early geneticists missed a lot when they looked at DNA only for its coding function.
