According to biblical chronology, the worldwide Flood as described in Genesis occurred less than 5,500 years ago. Noah’s three sons and their wives repopulated the Earth after the great flood. Therefore, creation researchers should discover this timeframe in human DNA. A recent study employing vast newly accessible high quality DNA sequence data for the human Y-chromosome stunningly verifies the prior findings and reinforces the Bible’s account of modern human beginnings (Tomkins, 2019).
According to the Bible’s chronology and genealogy, God created humanity less than 10,000 years ago, as Adam and Eve. However, less than 5,500 years ago, only Noah’s three sons’ and their spouses’ DNA was utilized to repopulate the Earth. This bottleneck must be considered while studying DNA. These biblical dates contradict evolutionary theory that modern people evolved from ancestors moving out of Africa 100,000-200,000 years ago (Tomkins, 2019).
This newer DNA sequence for the Y-chromosome included significantly longer contiguous DNA sections, which helped settle the debate. Due to the lack of a chromosomal homologue in the human genome, the Y-chromosome is especially relevant in investigating human pedigrees and mutations. When sperm and egg cells develop, the 22 autosome pairs exchange DNA segments. The Y-chromosome is genetically stable and hence important in genetic clock investigations (Tomkins, 2019).
If humans have been around for several hundred thousand years or longer, they should have acquired 8 to 59 times the quantity of mutations seen in the Y-chromosome DNA sequence. However, the new analysis shows that the human Y chromosome record shows less than 5,500 years of mutation accumu
This study adds an independent line of evidence to the genetic argument for young-earth origin. Previous research on female DNA revealed the recent beginning of mankind at creation and the Flood via Noah’s son’s brides. The current research demonstrates that male DNA also reflects the same timeline. These new findings not only disprove evolutionary theory, but also validate the biblical account of mankind’s recent beginnings.
