I think the idea of there being health issues in certain types of mixed families is super interesting because that almost certainly would have been noticed and lead to certain cultural practices or taboos within both species' societies.
Uh yeah because it's a movie. They couldn't pass up on casting Kermit the Frog and Miss Piggy as Bob and Emily Cratchet (what with Miss Piggy's sheer talent and star power) which left them in a bit of a casting bind. Realistically they had to cast pigs and frogs as the Cratchet children instead of searching high and low for talented half-pig half-frog child actors. Even then they went out of their way in casting Kermit's actual nephew Robin the Frog as Tiny Tim and the other child actors (Peter, Miranda, and Melinda) pretty closely resembled their 'parents'.
Whether the Testimonium Flavianumin (Josephus' description of Jesus in Antiquities) was entirely a Christian insert or the section was just edited by Christians is debated, however there's consensus that Josephus' reference to "the brother of Jesus, who was called Christ, whose name was James" in Antiquities is authentic.
This completely fails to address the actual gaps in scientific animal care legislation, in this case lack of oversight to make sure they actually adhered to the CCAC guidelines and a major lack of transparency. This legislation just sets back science that has good reason to use dogs as model organisms while letting abuse of other animals continue (especially non-government-funded work which has no requirement to follow CCAC rules!)
