I just stepped on a rosebush and I'd like to know: who the hell is responsible for plants having thorns on 'em??
EVOLUTION
FINE.
Which the hell evolutionary forces are responsible for plants having thorns on 'em??
I think it's that animals eat the plants, so plants with thorns get eaten less!
ANIMALS. I knew it!! Animals are ALWAYS trying to play me as if my name was Sega!
Well, if you'll excuse me, I'M off to go eat parts of a cow and feel even MORE justified than normal, thanks!!
Thorns are modified stems: roses technically have "prickles", not thorns.
OKAY FINE WHATEVER
Also, the evolutionary forces that produced rose prickles include being able to attach to other vegetation easier which helps growth, and being able to trap wind-blown sand which protects a rose's roots. If you want to revenge yourself, dude, revenge yourself on sand.
