Last summer, astrophysicist Neil DeGrasse Tyson was asked to comment on the furor surrounding genetically modified organisms (GMOs). He responded with the assertion that humans have been genetically modifying organisms for millennia, giving us food crops such as seedless watermelons or corn. This process, he stated, is little different from genetic engineering.… Tyson's first mistake lies in his equation of artificial selection and genetic modification, reflecting common misunderstandings of both the sources of genetic variation and the distinction between the latter and mechanisms of evolutionary change. Tyson's second mistake is his failure to see the bigger picture. The dynamic of capital accumulation is fundamentally at odds with ecosystem dynamics. And technology, in our society, is the handmaiden of capital accumulation. This article will elaborate on these distinctions and discuss some of the basic biological processes underlying GMOs and their potential risks, especially risks of dispersal. It will then examine how capitalism molds the technology and accentuates the risks.
