Yesterday night this question suddenly came to me. I realised that althought I have always assumed they have the same number of ribs, I have not actually confirmed this fact.
So a quick search landed me on this interesting site that answered my question with science and logic, along with many more myths originating from christian faith (mainly the bible) It was sort of a mini wiki on the subject and I couldn’t help but spend a few hours reading through topics such as How old is the earth according to the Bible? and How did dinosaurs fit on Noah’s Ark? While many of the responses are a tad bias, using the bible as evidence, it nonetheless presented many ideas and facts that proofed to be interesting read.
