“As for randomness not producing the designs we see in the cell. You seem to forget that only part of the process of evolution is random.”

First all mutations are not repaired, most are repaired, a few kill the cell
When you say design do you imply a designer that is an entity?
Because it is such a simple system it takes less imagination to see how it evolved.

First, falsefiable doesn't mean false. It means a theory that can be tested
The lac operon has only a handful of parts, non of which will mean instant death if it's missing. Once the bits of the system finally get together in the same E coli it gives a very nice advantage of not wasting recources on lactose metabolic machinery when it's not needed. It's just a few mutations. No need to get God involved. Just give the little beasties some time.

First define species, relatively easy for sexually reproducing organisms, very difficult for bacteria. Bacteria would be nice because of the relatively short time per generation but the definition problem makes this a non starter.
Another place to look is in a very small system like Darwins finches in the Galopago islands. "The Beak of The Finch" chronicles the Grants' herculean multiyear study of these finches separating into 3 species during bad years and hybridizing back into one big genetic blob during high rainfall years. It's quite readable. They actually captured, measured, and followed every single bird on the Island for many years.
noun, singular or plural: species
(1) The lowest taxonomic rank, and the most basic unit or category of biological classification.
(2) An individual belonging to a group of organisms (or the entire group itself) having common characteristics and (usually) are capable of mating with one another.
A species is given a two-part name: the generic name and the specific name (or specific epithet). For example, Allium cepa (commonly known as onion)
I'm still curious about your version of a designer. Please describe
The reason I don't site peer revieved papers in this forum is that I agree with Albert Einstien when he said (aproximately) You can't say you understand a theory until you can explain it to your grandmother.
