(Brett Tingley) Here it is: the moment historians will look back upon as the dawn of Homo sapiens superior and the moment when us natural-borns get knocked down a peg on the social hierarchy.
For decades, science fiction writers have foretold a future in which genetically-superior humans made possible by gene modification techniques will rise above us lowly normies with their enhanced intelligence and physiology, greater resistance to diseases, and stunning good looks of course. The prospect of editing the human genome has remained taboo, though, for longstanding ethical and moral reasons. Naturally, human-rights-optional China has ignored these and blazed ahead and given the world its first two genetically-modified superbabies whether we want them or not. It begins.
Evolution is just too slow.

This isn’t the first time Chinese scientists have tested CRISPR on humans. As early as 2015, Chinese researchers were already altering the genomes of human embryos in laboratories – embryos which were never gestated. Now, geneticists Southern University of Science and Technology, in Shenzhen have taken these techniques one step further by modifying the genomes of two embryos which were implanted into a human womb via in vitro fertilization. Those embryos are now two happy and healthy baby girls, Lulu and Nana. Scientists led by He Jiankui altered the girls’ genomes so that they will be immune to HIV – in theory. In statements made this week, He assures that the only changes made to the girls’ genomes were to the “doorway” which would allow HIV to potentially infect the girls. Who knows what unforeseen consequences might arise from the editing process, though?
The research has not yet been submitted for peer review and publication, so many scientists remain skeptical of the Chinese team’s claims. Jennifer Doudna, a biochemist at the University of California, Berkeley who helped develop CRISPR-Cas9 gene editing, warns that this trial is a “break from the cautious and transparent approach of the global scientific community’s application of CRISPR-Cas9 for human germline editing” adding that she and other scientists around the world are still “struggling to figure out what was done and also whether the process was done properly. We just don’t know yet.”
What will the future bring us now that we have the potential to alter the human genome as we see fit?
Many nations experimented with eugenics and other controlled breeding programs throughout the 20th century, but the advances made by CRISPR and other recent technologies let scientists remove all uncertainty from the equation (in theory) and edit the human genome on a gene-by-gene basis, opening the doors for all sorts of modifications with unknown long-term consequences.
