Magic embryology: physical forces form organs (Introduction)

DAVID: Out of an original jumble of cells organs take shape and form guided by physical shapes and forces:

QUOTES: "'In a nutshell, we discovered a fundamental physical mechanism that cells use to mold embryonic tissues into their functional 3-D shapes."
"Cells coordinate by exchanging biochemical signals, but they also hold to and push on each other to build the body structures we need to live, such as the eyes, lungs and heart. And, as it turns out, sculpting the embryo is not far from glass molding or 3-D printing.

DAVID: Getting to fertilized egg to whole new organism requires major planned processes which are all coordinated in achieving the new whole one. There is no way a Darwin process could have developed this process. It is totally unexplained from an evolutionary standpoint. It had to be designed from the beginning.

Cells coordinate or cooperate in using an amazingly flexible mechanism to create new structures as well as to repeat existing ones. This discovery suggests that from the very beginning cells had the "fundamental physical mechanism" to produce all the varieties of life in evolution’s history, and they also had the means of cooperating in order to use that mechanism. You claim that every twist and turn in the history of cellular cooperation was divinely preprogrammed or dabbled, but as it is impossible to tell the difference between automatic and autonomous behaviour, this cooperation could just as well be brought about by interaction between intelligent organisms (cells) - allowing, as always, for both mechanism and intelligence to be the work of your designer God. This ties in with the entry under "Immunity" (and thank you for both articles):

QUOTES: Macrophages are cells critical to the immune system – and new imaging reveals how they actively monitor their surroundings, searching for invaders.

The cells are highly specialised. They are the body’s frontline troops when it comes to detecting, combatting and destroying invading bacteria and other unwanted microbes.

“'This is discovery science at the cutting edge of microscopy and reveals how much we still have to learn about how cells function.'”

I am struck by the parallel with ant communities – different types of ant/cell perform different functions within the colony/body, and it is the task of certain ants/cells to be the frontline troops in detecting, combating and destroying any invaders. It would be interesting to know how many people believe ants to be automatons, and if they opt for ant intelligence, to ask how they differentiate between ant and cellular behaviour.
