Humans share 98.5% of our genes with chimpanzees
The genome is not a blueprint for constructing a body; it is a recipe for baking a body.
As the hox story illustrates, DNA promoters express themselves in the fourth dimension; their timing is all. A chimp has a different head from a human being not because it has a different blueprint for the head, but because it grows the jaws for longer and the cranium for less long than a human being. The difference is all timing.
The startling new truth that has emerged from the human genome - that...Folksonomies: genetics

Even the difference between human and mouse blueprints are minor. Our variation comes from the schedules that manage the expression of genes, and these are controlled by the chemicals and enzymes in our environments.

The Mesh of Science
I do not think that truth becomes more primitive if we pursue it to simpler facts. For no fact in the world is instant, infinitesimal and ultimate, a single mark. There are, I hold, no atomic facts. In the language of science, every fact is a field—a crisscross of implications, those that lead to it and those that lead from it.
Truth in science is like Everest, an ordering of the facts. We organize our experience in patterns which, formalized. make the network of scientific laws. But scie...Science "articulates the movements of the world."
