Common ancestor with potentially a similar gut. That is not definitive against. The researchers have shown an unexpected effect. They do not know the pathway.

Common ancestor with potentially a similar gut. That is not definitive against. The researchers have shown an unexpected effect. They do not know the pathway. The fact the effect exists indicates there is some biochemistry at play that we did not expect to see. What that mechanism is, is not known. So, it is just a question mark, science does not know - and that is simply where we are. We don't know, and we don't even know the chances of the result carrying over to humans. It seems like science needs to identify the mechanism behind this result,then we can start looking at whether that mechanism also exists in humans and also if it functions in a similar way. We might have an enzyme that enhances the effect, or contrary, or not at all. Bottom line, no data is available to make any statements regarding human efficacy, it is a big fat - we do not know
