Is this tree leaf evolution?

I think I see understand your question now. You're wondering if you've caught evolution in the act.If you're observing changes from one generation to the next, then possibly you're observing evolution in action. It's also possible that you're just observing leaf forms within the normal range of variation for that species.If you're observing changes in the leaves of the same plant during its lifetime, then this is not evolution.--Percy
