Paper: Student Essay- Designing Methuselah: an ethical argument against germline genetic modification to prolong human longevity
I am 16 years old. I am at the start of my life and looking towards my future, deciding on universities, career options and how I want my life to be. At the moment I can expect to perhaps live to 90 years of age. To me, this seems like a pretty good life. If I was offered more would I take it? I’m not sure; perhaps, if my health and independence can be guaranteed, then yes, I might.
Scientists have identified genes in mice that regulate lifespan. They have then edited these genes and have bred mice that have lived a full generation longer than their peers. These genes have their equivalents in the human genome too. Gene editing is becoming more refined by the day and it is predictable that it will one day be technically possible to edit the genome of human embryos to extend their lifespan. Again, extending from mice trials humans with these same genes altered could live to around 130 years old, the equivalent of a whole extra generation.
Gene editing technology brings with it many exciting opportunities such as the possibility of ridding some individuals of disease causing genetic variants. The possibilities extend beyond this though. It is not an unlikely prospect that in my lifetime I will be faced with the choice of deciding if I want my children to have any genetic alterations. These alterations might not just be limited to lifespan extension either; it is foreseeable that enhancements to traits as varied as intelligence, appearance and athletic capability may be potentially on offer.
