DAVID: We know of no biological process or processes that produce new species.

dhw: So why do you keep harping on about them?

Because it is obvious evolution is based on new biochemistry being avaliable for new forms.

Immunity system: lung cells
DAVID: In design theory it is reasonably proposed lungs were first designed with these cells in place, or lunged species would not have survived.

dhw: Alternatively, fatalities would have resulted in the surviving cells gradually learning to improve their design. (You seem to think that every disease would obliterate the whole species!) A parallel would be most of our human inventions, which worked OK originally but were gradually improved on by subsequent generations.

After a time gap new species handle life very well. Means prepared in advance.

Magic embryology

QUOTE: The migrating cell has to constantly be making decisions and figuring out if it is in the in the right place in the body.

dhw: Don’t you just love these signs of intelligence?

The article shows tight signal controls, but I guess you ignored the descriptions, since they upset your rigid concept about how intelligent cells are, without being able to tell me how they got that way naturally. Try not scurrying back to a probable God to avoid the other side of the issue. If you are either or about God, give me the no God explanation.

DAVID: This shows how cells can operate fully by chemical signals in all cellular operations incuding epigenetics. The Speciation mechanism is totally unknown.

dhw: And because it is unknown, perhaps we should consider the possibility that cells decide which chemical signals should be used when and to what effect?

But just only in embryo formation they don't? Cells operate by physical and electrical and chemical signals/stimulations which trigger automatic responses.

Human membrane pore
DAVID: The concept [irreducible complexity] says all parts must be formed simultaneously. […]

dhw: All parts of what?

DAVID: Of the fully operating pore in this case.

dhw: […] Has this pore always been present in cells, or was it a new development? But in any case, I would not envisage intelligent cells cooperating to produce a necessary organ whose parts didn't work simultaneously. If it was necessary, they wouldn't survive.

DAVID: The pore, as a vital part, has been around since cells existed.

dhw: Thank you. As I commented before, I fully accept the irreducible complexity of the cell.

DAVID: It is newly described as to its molecular parts. I have bolded the part of your response which is the irreducible complexity theory originated by Behe.

dhw: So what is the problem? If one part doesn’t work, the mechanism won’t work. Fits in perfectly with the concept of intelligent cells cooperating to create a mechanism that works. However, see above for mechanisms that do work but can be improved.

So simple cell committees understand design for future use?

Ediacaran-Cambrian transition: 410,000 years

dhw: […] please tell me why you think the 2019 arguments explaining the gaps in the fossil record are no longer valid in 2022.

DAVID: I know all the arguments about gaps. All are theoretical guesses. Gould recognized the issue as so punctuated equilibrium was proposed, defended and opposed, nothing solved.

dhw: Of course they are all theoretical guesses. Does it not occur to you that the existence of God and his 3.8-billion-year programme or individual dabbles for all evolutionary changes are also “theoretical guesses”? Now please tell me why the 410,000-year transition invalidates all the “theoretical guesses” that explain the absence of fossils.

See Egnor's previous comments which you well know. If after decades of searching for more, and do not appear, there are no more. 160 years since Darwin worried about the Cambrain gap and what we have found is the time is shortened, and gap stronger than ever.
