I have come across this video which put forth the hypothesis that bramble actually qualifies as a carnivorous plant. The observations that have led to the hypothesis are:
1. Sheep getting caught frequently in bramble
2. Sheep will die without human intervention.
3. The rotting corpse of the sheep will nourish the plant for many days.
4. The thorns angle inward -- supposedly evidence for adaptation that helps trap prey animal.
I agree , on the surface it looks plain silly but that is a reflexive reaction, not an argument. Is this a plausible hypothesis? If not , please give reasons.
