Second, it’s the baby’s lung, it’s a waste-disposal system, and it’s a nutrition source.” […] “Half of the fetus is maternal, the other half is paternal, and yet the pregnancy can go on for nine months without the mom’s body destroying it,” Barroeta said. “And that, from an immune standpoint, is fascinating, because if you were to receive a piece of someone else and insert that under your skin, that would not last there for three days, your body will actively reject it.” […] This wall of cells keeps mom and baby working in harmony and not killing each other. […] When evolutionary biologists mapped the genomes of these cells, they found that the protein that allowed these cells to fuse into a wall, called syncytin, didn’t look like it came from human DNA. It looked more like HIV. According to Chuong, this protein actually came from an ancient retrovirus, the most famous of which is HIV.

[…] Trump is not alone in seizing this advantage. Late last year, a grainy video surfaced of a ruling-party Taiwanese politician entering a hotel with a woman, indicating he was having an affair. Commentators and other politicians quickly came to his defense, saying the footage was AI-generated — though it remains unclear whether it actually was.
