Plants have family values, too, it ems, with new rearch suggesting they can recognize clo relatives in order to work together.
An ability to tell family from strangers is well known in animals, allowing them to cooperate and share resources, but plants may posss 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.

ur neighbor is also not being competitive.”
