Sorry, that happens not to be the case.
There are many areas of the world where DNA from prior to 4350 years ago is the same as after 4350 years ago.
There was no replacement with Noah's family's DNA.
In other words, no global flood 4350 years ago. That is a religious belief with no scientific evidence.
(By the way, AnswersInGenesis is not a science website. They are peddlin' pure apologetics. Pay them no mind.)
[[There was no replacement with Noah’s family’s DNA]]
woah Woah Woah- According to evolution, we all come from a single line- ya know, common ancestry and all that? No replacement of DNA?
Face it, the bible is true, and htose sights you been hitting? They been peddling you pure apologetics- Pay them no mind
