"Test the limits of theories of change"??
Please explain, I don't know what that phrase means.
Cheers!

I am referring to Behe's Edge of evolution, which asserts that two simultaneous mutations required for a new function are statistically impossible (something never posited by evolution theorists).
Behe say the next best thing is also impossible -- two sequential mutations, the first of which confers no benefit -- are also impossible.
Testing this is time consuming -- it can take decades -- but at least two laboratory experiments have demonstrated two and even three sequential mutations resulting in a new function. An equivalent multi-mutation sequence has occurred in the AIDS virus in historic times.
These cases confirm what theorists have claimed for the past 50 years -- that neutral and even mildly detrimental mutations can accumulate in a population and can become part of a new function, being bridged, so to speak, by a single enabling mutation. what was once theory is becoming laboratory science.
