That’s fine, but would the six species be characterized as anything else other than mice? BTW, Madeira mice look like regular mice to me. Here is the link you wanted: SPECIATION? - - One Species turns into Six Chromosomal Races (amended)
That’s fine. We’ll set up several experiments with different Baseline bacteria. One should pan out eventually …or else.
There are several definitions indeed, but referring to “Common descent”, how would you directly test this other than by obtaining a Threshold organism descended in the lab from a Baseline organism, yet different enough to not be classified as a Baseline organism?
Hang loose, dude!
