So many questions remain unanswered. Perhaps we are poorer for having lost a possible explanation or richer for having gained a mystery. But aren't both possibilities equally intriguing?

Trees live in symbiosis with hyphae (fungus/mold roots). A tea spoon of dirt contains kilometers of these roots. One species can spread throughout entire forests over centuries. They exchange nutrients with trees, along with information about insects, drought and other dangers. It's like a 'wood wide web'.

A good upbringing is necessary for a long life, but sometimes the patience of the young trees is sorely tested. As I mentioned in chapter 5, "Tree Lottery," acorns and beechnuts fall at the feet of large "mother trees." Dr. Suzanne Simard, who helped discover maternal instincts in trees, describes mother trees as dominant trees widely linked to other trees in the forest through their fungal-root connections. These trees pass their legacy on to the next generation and exert their influence in the upbringing of the youngsters. "My" small beech trees, which have by now been waiting for at least eighty years, are standing under mother trees that are about two hundred years old -- the equivalent of forty-year-olds in human terms. The stunted trees can probably expect another two hundred years of twiddling their thumbs before it is finally their turn. The wait time is, however, made bearable. Their mothers are in contact with them through their root systems, and they pass along sugar and other nutrients. You might even say they are nursing their babies.
