Is stranger than that. Would be the only carnivoronus monocot known by now, (the only that I'm aware at least), so from an evolutionary point of view is a totally new type of creature. Would be like finding a monkey with wings. Evolving to a partially carnivorous diet in plants is a very rare event even among dicots. Only a few lamiales can do that.

So I would say that I'm a little skeptical, but hopeful. The deletion in the genome could have other parallel causes also (adaptation to the same very acid soils were carnivorous plants live would be my first candidate).

Very interesting idea in any case.

Earlier quoted context omitted.

I don't see the contradiction here?

How do they know there's fewer than 1000 if they barely noticed this one in front of them?

4000 years of Botanical research since egyptians, duh...

I like the technique of testing if it was carnivorous. For the lazy people, they put a nitrogen isotope inside fruitflies and then tested the plant later to see if it was absorbing the nitrogen, and it was.

By this definition (nutrient uptake from an animal the plant has killed), brambles should be counted as carnivorous.

Their spines all point towards the base of the plant, where, in a mature specimen, there’s usually a hollow without thorns.

Thing is, if you’re a furry or woolly animal, like a sheep, and you get caught in the thorns, your struggles bring you into the centre of the plant, where you’re thoroughly trapped, and you die of exhaustion.

Then you decompose, and the bramble gets fed.

I’ve seen this happen to sheep, and here, while clearing huge swathes of giant brambles, it’s not uncommon to find a skull or a few bits of bone around the bottom of a plant.

Whoa. That's a really cool thought; I had never considered that.

There is a case to be made that this should count as predation.

The plant in the article is less ambiguous: they detected a digestive enzyme in the sticky stalks which is common to other carnivorous plants, and means the plant digests the insects directly.

A bramble consumes unlucky mammals with the help of mycorrhisae in the soil, rather doing so directly. Is this more like the bacteria which help ruminants digest cellulose (no one would say that cows don't eat grass!) or is it more like saying that vegans are carnivores because organic fertilizers have blood and fish meal in them?
