QUOTES: We are a bundle of clocks that are synchronized to the environment by zeitgebers, of which changes in light and darkness are but just one.

"[…] we tend to be awake mostly when light signals tell us to be."

DAVID: this system is controlled by light and depends on specific molecular feedback loops. Only design can create this system.

dhw: The whole article clearly describes how organisms respond and adapt to the environment. If they didn’t, they would not survive. According to you, every single response by every single organism has been specially designed by your God and geared to the creation of H. sapiens. There is nothing in this article that can be used to exclude the possibility that the cell communities of each organism have adjusted themselves to the conditions – which for a theist would mean that God designed the autonomous mechanism enabling each organism to work out its own “specific molecular feedback loops”.

This theist disagrees. Feedback oops are critically designed t o control all the metabolic functions of life. They are automatically in place in a ll of us from birth .
