"If evolution is happening continuosly right now should there be at lest one example of a species improved?"
I think you are noticing something with great scientific validity. First, let me digress.
I agree things are going down hill -- even more since I was not allowed to teach biology, being administratively removed from the biology methods course by an Afro-American PhDude who was making $77,000 a year at the time, back when that was real money -- with no reason but apparent dismay that a red-haired guy was walking the Earth.
And all the conservatives and liberals and intellectuals put together could not figure out that my rights were significantly violated -- and they continue to send me whopping bills, with interest, for the incomplete training experience, replete with multiple harassments, which they 'gave' me.
To clarify...and I've written on this before in this forum..."improvement" is not really what evolution does. The creatures which live to reproduce form gene lines (informal term) which are changed by each successive generation. There is no guarantee anything now living will have living descendants 1,000 years from now; hence, there is no proof they have actually achieved "improvement" ever...until you define improvement.
Plus, as we mentioned, if you have 10 million years and a bird line reproducing after 1 or 2 years, you have 5-10 million generations. You don't have to have a noticeable change in 50 years to make a lot of changes.
"Also scientist have said that things like the fruit fly have stopped evolving. What?"
Please show me who said that and the full context of what they said.
