Like a well-written, trillion-page novel, every micro-step, every macro-step, every twist and turn of our development follows a master plan.
The way an embryo develops shows a method of patterning that makes use of physical processes as if they conform to a predetermined plan.
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.
Scientists are delving into the remarkable way a zygote grows through its embryonic stages to an adult.
