Science writer David Dobbs has definitively described the voracious appetite of the “selfish gene” meme, pointing out that the notion of individual genes exercising power on the outcome of events has been so good at mass producing itself, that “the selfish gene has become a selfish meme.”
At CGS, we have another name for this phenomenon: the gene of the week.
All “genes of the week” have something in common: they never actually live up to their billing. For starters, it is never true that a single gene just does something. Genes work together, and genomes work with their environments. But this inconvenient reality has done amazingly little to stem genetic determinism, or the funding of research that relies upon its framework.
How could this be true? Is it really the case, as Dobbs posits, that “the gene-centric model survives because simplicity is a hugely advantageous trait for an idea to possess?”
The adventures of “smart genes” provide an illuminating case study.
There are some people who really want to find the genetic basis of intelligence. The sole effort of BGI’s Cognitive Genomics Lab, for example, is to investigate the genetics of human cognition. The fascinating documentary film DNA Dreams sheds light on the hopes of those involved with this project. They harbor no doubt that there is a genetic basis for intelligence; the only question is when they’ll uncover it and how limitless the possibilities will be once they do. Embryo selection and modification to ensure smarter babies are among the future scenarios they envision.
