How Does Wood Come into Existence?
Which part of a 2000-year-old olive tree has already existed at the time Jesus walked the earth? The development of a tree begins with the sprouting of a seedling.
Every year, the young tree is being covered by a new thin layer of wood cells. The growth is happening on the outer skin, right under the bark of the tree.
You can find out the age of the tree by counting the growth rings.
