Since English is not my mother language, please, excuse possible errors.
If you look into my avatar (you may use my "profile" for a better definition), you will see a tree leaf. If you have some interest in nature and botanics, you will notice that it is a compound leaf, but the leaflets are not identical. This comes from a tree that belongs to the Aceraceae family (maples).
Now my question is: Is this evolution in working?. If you think "yes", explain reasons why. The same if you thing the answer is "no". Your explenations will be appreciated.
Edited by Adminnemooseus, : Added the "tree leaf" part to the topic title.

Creationism and evolutionism should not be mutually excluding.

Could you describe what you'd like to discuss in a little bit more detail, because the question as you have phrased it has a very simple answer: evolution happens during reproduction, not growth. What is it you'd actually like to discuss?

When I pruned this tree, an Acer Negundo that has grown by itself in a wallnut plantation, I realized that the leaves, contrary to what I am used to see, (and I have pruned many trees), where quite different betwen them. I have more pictures, and expect to put them in a place that can be reached by Internet.
Aceraceae species, in general, have lobed leaves. There are some exceptions, like Acer Negundo, that has composed leaves. The more I look to the pictures I have of these leaves, the more I think Acer Negundo is in the way of evolving versus lobed leaves.
My opinion is that this evolving process is possible, but would like to check it with more informed forum members.
I am not completely in accordance with your statement, that evolution only happens during reproduction, but I do not want to go deep into that debate for the time being.
