Why the religious will never admit you won the argument (and why they don't care)

[SteveII]

There is no tree anymore thanks to genetic studies. Different genes tell contradictory evolutionary stories. "Webs" or "networks" of relationships are now hypothesized. Interesting stuff. It illustrates that an idea (the tree) that was believed to be true since Darwin drew it is even still believed to be the case today on a popular level, but really is/has been tossed out in favor of other theories by scientist.

And how is that a gap?

It's a gap in knowledge, in understanding of how it works. That is my whole point. You can't simply say vague things like "evolution is fact". You have to be more specific.
