Genesis correctly predicts Y-Chromosome pattern

Jews and Arabs shown to be descendants of one man!

Y chromosome evidence is consistent with the Bible’s teaching that Abraham would be the ancestor of a great nation, namely Israel or the Jews, and that the Arabs are also children of Abraham (via Ishmael). It is also consistent with the Biblical teaching that all Jewish priests are descendants of Aaron.
The same evidence confirms that all Jewish people groups today really are physical descendants of Abraham, not from Khazar converts, while the British people are not physical descendants of Abraham.
Jesus Himself, while fully God, is a Jew and a descendant of Abraham. Both Jews and Gentiles can become spiritual descendants of Abraham by believing on Jesus.
