Did they follow the reasoning to the conclusion that humans and pigs have a common ancestor? Is this accepted by modern Islam?
What's your intention behind this question?
I'm wondering if the idea of common descend, that an actual individual animal is the grand-grand-grand-father of all living mammals, which derives from the theory of evolution, is accepted by modern Islam or was intuited by these scholars. Not merely shared properties, lineage. I'm wondering this because I would find it surprising and fascinating.
