Clock biologists all appreciated that the communication went one direction--from the clock to biological processes--but I don't think anyone anticipated that there would be this level of integration with cell metabolism and the cell cycle, or all these other pathways impinging on clock function.
Of course this level of sophistication was not anticipated by evolutionists because, like the Epicureans, they believe those "veering atoms" just happened to create the most complex structures known. And now that the biological clock's elaborate genetic network is better understood, evolutionists believe it just built up due to a series of mutations that just happened to occur. Amazing.
This might seem improbable but remember, we're not allowed to be incredulous regarding evolution. After all, it is a fact.
