Sound like the "Mark of the Beast."
Maybe the turtle carrying the flat earth on his back isn't crawling through space as fast anymore.
Since you asked, the long answer:
"The wrath of God is being revealed from heaven against all the godlessness and wickedness of people, who suppress the truth by their wickedness, since what may be known about God is plain to them, because God has made it plain to them. For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse.
"For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened. Although they claimed to be wise, they became fools and exchanged the glory of the immortal God for images made to look like a mortal human being and birds and animals and reptiles.
"Therefore God gave them over in the sinful desires of their hearts to sexual impurity for the degrading of their bodies with one another. They exchanged the truth about God for a lie, and worshiped and served created things rather than the Creator—who is forever praised. Amen."
Romans 1:18-25
And like dog breeding, if you keep focusing on the traits you want as you breed your animals over time, you eventually get those effects/traits you want, but undesirable side effects can creep in.
Take Dachshunds for example. They've been bred over the years to accentuate long backs and short legs, but the consequences are that dachshunds now may develop ruptured spinal discs due to their long backs, leading to paralysis and/or chronic pain.
Who knows what the long term effects of trying to selectively breed humans might be?
