Can a plant tree evolve from a different type?

Question

thankyou

Answer 1

What is a plant tree?

Answer 2

You question is a little vague.  Species evolve from existing species.  Changes are usually subtle such as resistance to fire or insects or more efficient growth in a given habitat.  A palm tree won't spontaneously become a peach tree!

Answer 3

No, it cannot. "Variation within a 'kind'" is not evolution, which is all that is ever observed. One kind of plant or animal cannot change into another "kind", no matter how much time you give it. There is a "black box" around each "kind" outside of which change is impossible. There can be variation *within* that box, but there are genetic barriers that prevent change outside of it.

For example, the "dog" kind (which includes all 250+ breeds of domestic dogs, as well as wolves, coyotes dingoes and jackals - foxes may actually belong to a different "kind", since they have the eyes of a cat - a major structural difference from dogs), can produce all these varieties but never, ever in a million years will produce a cat, no matter how long you breed them and no matter how extreme the variations you get. You will ALWAYS get some kind of a "dog", 100% of the time, guaranteed.

If a cat cannot be produced out of a dog by forward evolution, then it stands to reason that they cannot have a common ancestor, either. What cannot happen now, didn't happen then.

Likewise, trees and plants can ONLY bring forth after their own "kind"; there may be varieties, but they are always the same kind of plant. There are hundreds of varieties of corn today, any corn farmer will tell you that. But they are all corn! They will never turn into barley, wheat, or tomatoes.
