The evidence is that teleology isn’t used in science.
It’s now been said several times that the purpose of doing science, like cooking paella and putting on trousers, isn’t teleology, since teleology is a doctrine of final causes. Modern science doesn’t concern itself with final causes, that’s something for metaphysics.
It’s been that way for 400 years. As Cardinal Joseph Ratzinger observed
“Evidently it must have been taught differently at one time or else Galileo would never have been put on trial.” - catholicbridge.com/catholic/ratzinger_creationism.php
In 1620 Francis Bacon wrote:
“Those who have taken upon them to lay down the law of nature as a thing already searched out and understood, whether they have spoken in simple assurance or professional affectation, have therein done philosophy and the sciences great injury. For as they have been successful in inducing belief, so they have been effective in quenching and stopping inquiry; …] Those on the other hand who have taken a contrary course, and asserted that absolutely nothing can be known …] have neither started from true principles nor rested in the just conclusion, zeal and affectation having carried them much too far.” - The New Organon, author’s preface
And to overcome what we now see as a fixation on Aristotle and unwarranted literalism (see JPII’s apology for the Galileo Affair), Bacon then proposes the division between science and metaphysics which defines modern science to this day:
"From the two kinds of axioms which have been spoken of arises a just division of philosophy and the sciences, taking the received terms (which come nearest to express the thing) in a sense agreeable to my own views. Thus, let the investigation of forms, which are (in the eye of reason at least, and in their essential law) eternal and immutable, constitute Metaphysics; and let the investigation of the efficient cause, and of matter, and of the latent process, and the latent configuration (all of which have reference to the common and ordinary course of nature, not to her eternal and fundamental laws) constitute Physics." -

Now this is time consuming, how about you read up and try not to keep forgetting.
