I didn't see the brain size argument in the comments, and I've always blindly assumed that's true since I heard it from saifdean. He also taught me plants are poisonous, since they can't run to evade being eaten. I joke, but on some level I believe these things. Have never researched the subject much, as you may have surmised by this point in my reply, but appreciate you taking a stand on this unpopular topic
