As any historical science, including geology, astronomy and so on. How did this mountain range, or river form? What are all those “holes” on the moon’s surface? Could they be craters? When did they happen?
Scientists draw from observations, and build models to explain data that is the result of past events.
Genetic drift is observed, and then postulated to be the way that the genome can bridge the gap of the current functioning gene to a new functioning gene.
Genetic drift is one part of some models that explain how some genes changed over time.
Is that the kind of detail?
Since you’re speaking in vague generalities instead of specifics, no. Evolutionary biologists can actually give remarkably precise models for how certain genes evolved, and how they changed and diversified over time, and back it up with experiments that corroborate those models.
I’d be very impressed if IDcreationists could do something even remotely similar. Explain when some gene was created, how it was created, what mechanisms were involved. Especially if they could show the invisible disembodied spook that can use it’s occult powers to wish functional proteins, if not entire living cells, or large multicellular organisms, entire populations of them, into existence. That’d be truly amazing.
Is the thread asking for a narative of a sythetic biologist as the explanatory process?
No I wouldn’t put the bar that high, I think IDcreationists should first learn to crawl before we ask them to even dream about matching the explanatory power of evolution.
