If you just watch the video below, about Alaska and Florida Rabbits
you will learn about one of the examples of common descent that even many Evangelicals accept.
"As introduced by Socratic Fanatic: "Youtube’s Potholer54 . . . [‘Potholer54’ is the name of the YouTube user/channel who has a strong interest in debating with YEC’s] . . . has a great video were he explains how even Kent Hovind had come to agree with the idea of evolution—as long the word is avoided . . . . I sometimes use that video as an example of directly observing macroevolution today, because a North American rabbit species has diversified to where Florida rabbits of that species can’t/won’t breed with [Alaska] rabbits . . . . but rabbits living in the Midwest can breed with both.

What is the Evidence for Evolution? - #11 by Socratic.Fanatic ]
The leading cause for common descent leading to 2 populations that cannot breed with each other is through “independent mutation” of the populations (usually when separated by significant barriers or distance). In Birds, such failures to breed can be triggered by “innovations in song”, making mates from the other population treat the candidate like a completely different animal.
But I don’t think too many people have heard rabbits sing…
A final thought … please note that some of the exhibits at the Ark Encounter include references to “limited” evolution… apparently they have no problem with mutation rates being ordinarily sufficient to support “change” over time:
"This origin of species from a common ancestor occurred by evolutionary processes. This is made clear by an exhibit on the Ark Encounter where we learn that, “species give rise to new species, modified characteristics develop over time, and the fittest animals survive.”
" This is a reasonable description of Darwin’s explanation for the origin of species by means of natural selection. Many visitors to the Ark Encounter may be surprised to discover exhibits which embrace Darwin’s mechanism – natural selection – for producing new species albeit with some strict limits. "
"Along with other natural mechanisms of change the Ark Encounter has proposed what I call a “post-flood rapid speciation model” of modern biological diversity to solve the problem of the limited dimensions and manpower of Noah’s Ark.
