I've never heard of Dollo; who was he and what was his bad theory?

Yeah that's fair, it's annoying to see the man moving

that said, the raptors in the original JP were also men in a suit - but they compensated to make it look closer to natural

Dollo was a scientist in the 1800s who created a theory that organisms can't re-evolve structures they lost. he didn't know genetics, so he didn't know that features can be turned on and off and thus it can be possible to re-evolve lost structures.

but, because of that theory, he and others decided birds couldn't be dinosaurs. this was because, at the time, we had no evidence of a dinosaur furcula (wishbone) - or, at least, we thought we had no evidence of one. We did, however, have "thecodonts" (early archosaurs) with wishbones - meaning that, if birds evolved from dinosaurs, they would have had to re-evolve the wishbone

turns out a) non-avialan dinosaurs did have wishbones, they just don't fossilize well b) we did have some, we just misidentified them and c) yeah you can redevelop things actually

so we went from birds being dinosaurs being the best supported hypothesis to almost no one believing it within a few years at the end of the 1800s

leading to the "dinosaur dark ages" (dinosaurs are slow evolutionary failures) that was the first 60 years of the 20th century
