A fossil is a standalone reality. Darwinism is a story that force-fits these standalone realities into a predetermined narrative. Watch how it is done.
Evolutionary storytelling about giraffes' long necks goes back before Darwin, but all the tales have one thing in common: they don't work. Doesn't matter. Evolution marches on.
When unrelated fossils have similar traits, evolutionary paleontologists twist, shove and stuff them into Darwin's theory with an all-purpose tool called convergence.
