DNA may, or may not change enough to cause species differences.
Animals, appearing similar to the ones we now have, existed long ago.
A hell of a lot of "could be"s and "maybe"s. And not a single documented case of a single species observably changing into a different, non-compatible (ie, can reproduce, but not with it's "original" family) animal.
And nothing "empirical."
