Gene Editing and Eugenics (Opinions Vary)

Critics of efforts to “improve” our species via heritable genetic modification are sometimes reluctant to call this “eugenics,” for fear that enhancement enthusiasts will derail the conversation by invoking Godwin’s law.

The argument against using eugenics as a frame of reference for new human biotechnologies is generally that the 20th-century variety was defined by state action (not entirely true), whereas human betterment enabled by 21st-century science will be a different thing entirely.

So it’s almost refreshing to read, in a respectable, albeit conservative, daily newspaper:

Eugenics need not be a dirty word — instead, it could be lifesaving technology

The article in question, by Madhumita Murgia who writes for Wired as well as the Daily Telegraph, was prompted by the fact that today the UK law comes into force that allows the use of nuclear replacement technology in attempts to avoid the births of children with mitochondrial (mtDNA) disease.

Murgia argues that

Eugenics is a dirty word, most commonly associated with racist profiling, or Nazi experiments. But the time has come to rethink our attitude. It can also be understood as manipulating the genome in order to solve human health crises.

At least she admits that mtDNA interventions do affect the germline, and are in practice eugenic. But there is a lot wrong with the piece. For instance:

  • Murgia ignores the fact the UK law allows clinical use of these biologically extreme techniques, without clinical trials or mandated follow-up.
  • She perpetuates the (at least partly discredited) claim that mitochondria have no influence on traits.
