You repeat a popular misinterpretation of the central dogma. The term was coined by Crick^, and actually says that once the information in nucleic acid goes into protein, you can't get it back out again.

So if you want to diagram it, it would be DNA/RNA --> Protein, where the arrow represents information flow.

Note that (rather ironically!) it was actually Watson who popularized the misinterpretation, in his college textbook. The reason I point this out is that there are many known violations of the Watson version of the central dogma, but none of the Crick version.

Also, I'd take issue with your claim that genes are like a blueprint. I'd say they're more like a recipe, as stated in the article (and I think your comment implies this anyway).

The larger point (that the article mostly ignores) centers around human vanity: we're actually not really much more complicated than many other species, especially our close relatives like the apes. Most of the differences between us and them are developmental, and you don't need many genes to produce such changes.
