My question stems (pardon the pun) from two ideas:
That trees live for a very long time and that there have been many evolutions of trees in that time.
It is possible to graft trees of the same genus together to form a tree composed of two different stocks.
Theoretically, if trees were held back from death, would it be possible to make a segment of trees tracking their evolution and following their ancestors?
For example, a branch of a lemon tree on the branch of the citrus ancestor tree, onto its ancestor, etc. until they reached the first tree. I think it could result in a tree that could produce every fruit of its lineage, but it's just a theory, right?
Obviously this is a purely theoretical idea, but I'm curious. Or, if it's not just a theoretical idea, and that trees could be "brought back" (like there are efforts for different animals).
