Is this your ignorance of the position of those you are arguing against or a demonstration of intentional dishonesty?
Do you even realize that you are conflating and equivocating the term "evolution" denoting "change", and saying that the same observation of change demonstrates "descent from common ancestry"?
Can you honestly not see a difference? Or perhaps intellectual honesty not a big concern...
Can you explain to me how all modern terrestrial species arose form those few that could fit on a boat of known dimensions sometime somewhat recently in the past?
What was the mechanism for how they got here then?
Would not one of the fox “kind” giving rise to all the present day fox species be an example of common descent?
How do you explain it?
