Asking for "the missing link" as evidence for evolution is ironically a good piece of evidence that we are dealing with a willfully ignorant person who argues strawmen.
You are not going to get the "missing link" for several reason:
- for starters, the concept is void and based on ignorance. It assumes the fossil record is the end-all, be-all of evidence for evolution while it absolutely isn't. The entire fossil record could disappear and the case for evolution would be as solid as ever.
- you won't be receiving examples of any "missing links" because by definition they are...... "missing"....
- it is a fundamentally dishonest concept to try and use it as evidence against evolution because there will ALWAYS be missing links in any historical evolutionary lineage. Say for example you have speciman A from 10 million years ago and specimen B from 5 million years ago. Then you'll yap about the "missing link" from the 5 million year gap. Let's say we find specimen C from 7.5 million years ago. "missing link" found? NOPE. In fact, this find just creates 2 additional "missing links"... one from 10 million to 7.5 million years and another from 7.5 million years till 5 million years.
So the only way to not have any "missing links" is the have a fossil from EVERY generation from EVERY lineage from the dawn of time till today. An absurd demand.
It's like me asking you of a photograph of your face of every second you were alive to "demonstrate" the claim that you are in fact aging.
Having said all that, I'll go back to my first point: we don't need a single fossil to demonstrate the accuracy of evolution theory. Extant DNA of species is all we require.
Fossils are nice and they sure support the theory. But they are not nearly on par as DNA is in terms of evidence for evolution theory.
