And on top of that, the balancing act is further complicated by its coordination with muscle development. As one writer explained:
The researchers went on to unpick the genes involved in this process, and came up with yet another surprising finding: that the whole process relies on first hitting so-called muscle genes in the embryo, which then provide signals to switch on the 'rib' genes to make both ribs and muscle, in a coordinated process.
Did evolution get lucky again by randomly constructing another complex, interdependent process that needs all the major components? Who knows but who cares. After all, evolution is a fact. As the lead researcher assures us, the perplexing result “makes perfect sense” from an evolutionary perspective. And why is that true? Because:
it is no good to make ribs without muscle, so, in the embryo, the production of both ribs and their associated muscles is under the control of a single and coordinated mechanism.
Of course. It is all so clear now. Evolution constructed incredible complexity because ribs are no good without muscles. That’s just the Stuff of Good Solid Scientific Research.
Religion drives science, and it matters.
