So I ended up reading Dembski’s own explanation at
The Explanatory Filter: Dembski, William A.
Some things I noticed.
1: He gave an example with voting ballotake, but not with animals.
2: At the end, he criticised scientists who looked at the universe’s age and size, but ignored that with the Earth’s age and universe’s size, those are actually fair to work with. And while he accused them of trying make the odds more favorable to evolution, Dembski could just as easily be accused of the reverse, by his logic.
And for what it’s worth, I’ll try a little bit of the filter with life.
Step 1: An a Law Explain it?
I would say yes. We observe genetic variance and that some genes end up being more harmful or helpful to surviving in an environment. And we observe that more successful genes tend get to get passed down more. With time, changes can accumulate to lead to a descendant looking decently different.
Step 2: Can it be Explained by Chance?
Well as was discussed in another thread, the odds are something occuring after it has occurred are 1 in 1. We can also look at variations and know that small changes happen, and that goes back to there being a law.
Step 3: Does it Serve a Purpose
Adaptations that get passed down do serve the purpose of survival. But then the question is if they were made for that. To look at that, we have to recall that the mutations that get passed down are the ones that were neutral/beneficial so it would be back to the law that useful ones get passed down.
So from my exercise, the filter ends with necessity/chance.
And a question for you, Buffalo. You’ve mentioned before the various kinds. Essentially that lions and tigers are just microevolution, a natural process, from some cat kind. (Am I wrong?) I reiterate this to bring it to mind and because there are some points I wish to expound upon depending on your answer. (If I recall correctly, it’ll be 'he’s bit I just want to double check.)
