The DNA evidence supporting evolution has only come about in the last 20 years as we have learned more about DNA and gene sequencing. PLEASE follow the link below to learn a little about DNA. Any anti-evolution argument you may present has to acknowledge the truth of DNA and THEN offer a rebuttal to it.

How genetic "markers" are passed to future generations; see it at https://genographic.nationalgeographic.com/genographic/lan/en/population.html
Briefly, how it's done
By following a marker back through the time to its origin, geneticists can identify the most recent common ancestor of everyone alive who carries a given marker. The divergent branches of the human family tree, represented by groups carrying a given marker, can be followed back to "nodes" on the tree where a mutation split a branch into two directions. Eventually, these branches can be followed backward all the way to a common African ancestor.
