Cellular intelligence: (Evolution)

T cells:

DAVID: You cannot use human 'learning' to fit the language in biochemistry. When the T cell recognizes non-self and thereby discovers a foreign protein is present, it automatically invents an answer which identifies the invader, by attaching a protein marker, which allows it to be destroyed or neutralized. That is learning in biochemical speak!!

dhw: So if cells already have God-given “algorithms” to correct errors and to kill foreign invaders, how do you account for the fact that vast numbers of victims (from bacteria to humans) can die before a solution to each new problem is found?

Errors are still present, re theodicy.

Baby immunity

DAVID: Only He can make new complex designs to handle the requirement 'when conditions change' introducing future requirements. Change always introduces the future and understanding the new challenges for new designs.

dhw: What do you mean by “change always introduces the future”? The new challenges are present, and meeting the challenge is essential in the present if the organism is to have a future! Why do you insist that innovations require gazing into a crystal ball? You know that adaptations are a RESPONSE to new conditions, so why shouldn’t innovations be the same, conducted by the same cells that produce adaptations?

DAVID: 'Adaptations' imply tiny steps, not the way to speciation which are giant steps into the future requiring major design.

dhw: It’s sometimes difficult to draw a borderline between adaptations and innovations (leg turning into flipper might be one example) but as usual you are missing or avoiding the point. We KNOW that small changes are a RESPONSE to new conditions. Why do you insist that large changes can only be made by anticipation of new conditions? Is it not far more logical to assume that all changes, large and small, will be a response rather than an act of clairvoyance? Why change something that is working perfectly well in the present?

We are discussing God, aren't we? How did evolution work, but by introducing new forms into their new future which I pose as designed by God.


dhw: To add to family woes, my computer is now playing extremely frustrating games. It has taken me all day to get onto the Internet! But my computer is now old, and there are no silicantibodies to counter the effects of silicold age. I shall have to get a new one!

Thankfully, competition brought us new cheap desktop computers.
