An ability to tell family from strangers is well known in animals, allowing them to cooperate and share resources, but plants may possess similar social skills, scientists believe.

Susan Dudley and Amanda File of McMaster University in Ontario, Canada, report they have demonstrated for the first time that plants can recognize their kin.

This suggests that plants, though lacking cognition and memory, are capable of complex social interactions.

"Plants have this kind of hidden but complicated social life," Dudley said.

"We hypothesized that plants have evolved to emit a secondary signal to help nearby relatives by promoting the recruitment of natural enemies [of the pest insects]," wrote Yutaka Kobayashi and Norio Yamamura in the latest issue of the journal Evolutionary Ecology.

Plants are also known to be able to identify close relatives to guard against inbreeding, Dudley, the Canadian scientist, added.

"They have self-incompatibility mechanisms where they recognize pollen," she said. "This stops them from being fertilized by their own pollen or by a plant that shares its genes."

I'm sorry you're having such a bad day.

Economics is a social phenomenon and in no way a “science”, no matter how desperately its high priests would like to have it believed otherwise. It is, instead, a branch of anthropology and the sooner that is recognized and accepted, the better off human-kind in general and the world of academic economics, in particular, shall be proximity1

We probably will see widespread civil disorder in the 1980s, as a direct result of our faltering economic system. Ron Paul

I've said it before, and I'll say it again:

VEGETARIANS ARE MURDERERS!!!!!!!!!

They uproot and hack down plants, who (not "which", WHO!) are peaceful and harming no one (and in fact convert CO2 to oxygen for our benefit),ripping them away from their relatives for their own selfish wants and desires.

It is a KNOWN fact that potatoes SCREAM when you pull them from the ground.

These vegetarians even eat BABY carrots! BABIES, for God's sake!!

plants, though lacking cognition and memory

And just how do we know that's correct???? I think man is just not smart enough to recognize the FACT that plants do indeed have "cognition and memory".

Baby-killers all!!

There ought to be a law.

Tag line: I wuz HACKED, cuz I SAY so!

(Boris Y) "I'd vote for obama"

(Mad Dog, Paul voter) IF RonniePAULIE runs as a repukelican't, (OR even as a demonRAT), against the messiah "king" obammy; I'd vote FOR him.

Call any vegetable & the chances are good that a vegetable will respond to you.
