The paper you link to actually seems more interesting to me than the one described in the OP. Definitely a different paper, though, unless the OP author was on crack.
Yeah, that's a different one, but you're right, it is way more interesting. What they've found is that the interactions of groups of proteins is very highly conserved, so proteins that work together towards a function in plants are still working together in humans, for example, even after millions of years of evolution. They use this to find a plant model for a neurological development disorder.
