  • Look at what humans have done with breeds of dogs. Before we even knew what genetics was, we understood that if you bred two small dogs, the offspring would be small. Then, if you bred those offspring with other small dogs, they would be even smaller still. That’s how we got from a wolf to a Chihuahua. That is how we manipulate the forces of evolution for our benefit.

    There are countless little “tells” that species evolve. Human skeletons have a tiny tail. All embryonic mammals look virtually identical. Whales have vestigial pelvis bones. Bacteria become resistant to antibiotics after generations of repeated exposure. Sickle cell anemia is an evolutionary adaptation in human populations frequently exposed to Malaria. Moths have been observed becoming darker in color so their camouflage matches trees darkened by pollution.

    A coworker of mine started falling down the YouTube conspiracy rabbit hole. He said something about the moon landing maybe being a hoax. I told him that when I was in college I used the big telescope to look at the moon landing site, so I knew for sure it was real. After that, he believed in the moon landing.

    Now of course I was lying about seeing the moon landing site. Terrestrial telescopes can’t see the landing site. I convinced my friend to believe the truth by countering a lie from a stranger with a lie from someone he trusts.
