Orphan genes — genes that are present in only one species, or a group of closely related species — are of particular interest to advocates of intelligent design.
I had someone ask whether, in a previous post, I meant universal common descent (UCD) or more limited common descent.
A reader asks, “I was just wondering why some fellows at Discovery believe in ID but still hold to common descent.“
In effect, protein engineers are using the power of random change plus intelligent design to see what if anything will improve function.
Our brains have vastly more ability than is needed for survival, most notably the capacity for language and abstract thought.
