Altering Genes In Wild Populations: Boon For Human Health? Or Darwinian Nightmare?
Imagine a technology that lets humans stack the deck against natural selection.
An altered gene of our choosing would replace a gene that occurs in a wild population. That change would then be passed from generation to generation. It’s a promising new technology that could eradicate malaria and control invasive species. But is that playing God? Is it a Darwinian nightmare?
Whatever it is, it’s no longer in the realm of the imaginary.
A team researchers, some from Harvard and MIT, recently released two papers outlining a feasible way to edit genes in wild populations. It’s done using a method known as “gene drive.”
The elements to create gene drive technology already exist but they haven’t yet been combined and tested in the lab. Before that happens, the researchers want to have a public discussion about the risks — like inadvertent species extinction — and benefits of this kind of gene manipulation.
WBUR’s Sacha Pfeiffer speaks with two of those researchers about the pros and cons of this technology.
