The only convincing argument in defense of macroevolution, in my opinion, is shared genetic mistakes.
Well ... what about all those intermediate forms?
Its subjective because at some point, one organism will always appear more closely related to another. That does not necessarily mean one is related.
But evolution
predicts which organisms will be most closely related by genetic criteria. We knew,
before we had the tools to test it, that birds should be genetically closer to crocodiles than to anything else, and that lobe-finned fish should be closer to, for example, mice, than to ray-finned fish. And we were right. "Subjective" doesn't come into it.
Evolution doesn't just predict that there should be genetic similarities between species, it predicts
which similarities, and the predictions are rather startling ... I mean,
birds and crocodiles? Or ...
whales and ungulates? Or ...
coelacanths and mice? These are really startling, outrageous predictions. And the predictions always turn out to be correct.
Like every creationist, you have confused the
interpretation of nature that we can make once we're certain that evolution is real with the
predictions we can make from evolution to test it if we want to find out if it's real. Evolution doesn't just tell us that birds should be genetically similar to
something, it tells us that they should be genetically similar to
crocodiles. Which turns out to be the case.
Sorry, complete derail. Back to the fairytale about the candle.
