Which makes sense, of course, given the enormous amount of influence our gestational environment can have on our genetic expression. 80 beats has the story:
Says lead researcher Carmen Sapienza said “By and large these children are just fine, it’s not like they have extra arms or extra heads, but they have a small risk of undesirable outcomes” [The Guardian]. Rather, the team found a very subtle impact. In 75 IVF babies and 100 naturally conceived ones, they examined 700 genes that particularly interested the researchers because they are linked to fat cell development, insulin signaling, and other functions associated with diseases for which people tend to be at higher risk as they age. The scientists checked DNA methylation, a modification to DNA which affects gene expression, and found that 5 to 10 percent of IVF babies had abnormal patterns of methylation.
I’d like to note that this is precisely what Habermas talks about in The Future of Human Nature and, by extension, would like to point out that his thesis is demonstrably false. Woops.
Bioethics is controversial.
No one endorses the ideas or concepts explored here, not even me.
You will develop a strong opinion about something you find here. I want to hear it. Philosophy is a conversation.
