That's interesting, but how do the plants go about doing this capture? It's not like the mammal droppings can choose to visit the plants, and if they somehow make their way to the plants, couldn't they always have done that? Did the plants somehow previously discard them but now not do that? Have the plants now taken on more of a toilet appearance to the mammals?

AFAIK, most plants benefit from manure / droppings. It is hard to believe, that carnivorous plants only recently started to benefit from this kind of opportunistic fertilization.
