To be fair, that was not what the architects of the Global Seed Vault were trying to do. We cannot just thaw out the past for a sustainable future. The flies are warning us that we cannot just thaw out the past for a sustainable future.Įvolution works by rules we sometimes don’t anticipate. Moreover, genomes shape ecosystems and environments the latter do not just select adapted genomes. But by allowing only one genome to run in the race by freezing the female genome at an ancient time, the females could not develop adaptations to compensate for the new male traits that harmed them.Įvolution works by rules we sometimes don’t anticipate. This encapsulates the arms race between the sexes in non-monogamous species. In nature, males with toxic semen would ultimately select females that were immune to it. While it seems counterintuitive to harm the mother of your unborn sons, the mutations reduced a female’s ability to be fertilized by another male and also modified the female behavior to be less receptive to mating a second time with other males. In that short period of time, males evolved seminal fluid that was toxic to the females, killing many. Any mutation that improved the number of sons a male fly sired would be better represented in subsequent generations. The males that produced the most sons contributed the most offspring to future generations, because only their sons were allowed to breed. In other words, the females’ genetics were frozen in time, insulated from evolution. The sons were allowed to mate with females from a monoculture of a specific genetic profile that could not change. That is about 40 generations, or 1,000 years in human time. William Rice at the University of California, Santa Cruz, collected only the sons of matings between fruit flies over the course of about a year. The hope of preserving biodiversity by only freezing genes from the past is naive.Ĭonsider what might happen when there is a conflict caused by mismatching old genes with new ecosystems. Ecosystems are the result of both genes and environment influencing each other. Biodiversity is a combination of all these potentials. What a gene does depends on where it is, in what genome, cell, or environment. Organisms are what they are because of their genes and the effects of the environment. Sadly, though, evolution could confound such good intentions. And those traits might well be ones that could protect the crop from catastrophic failure, or worse.” Preserving a great diversity of seeds can preserve some genetic diversity-and our ability to feed ourselves-in an adverse future. They are comprised of traits-genes-assembled from previous, even ancient varieties and populations. “New varieties do not spring into existence de novo. In his book Seeds on Ice (2016), Fowler explains his rationale for the seed bank. Let’s start with genetics, the science of genes. Even thinking that might invite disaster. But they are not insurance policies for the apocalypse. Gene banks can do important work to preserve biodiversity and be safety backups that help the world run more smoothly through crisis. Properly accounting for climate change was always only one problem with the vault, though. It may sound a bit far-fetched that the Brazilian constitution or Mexican historical documents need such protection, but apocalyptic scenarios need not be global - Syria was the first country to withdraw from the Global Seed Vault last year, and archives and government documents are often targeted in times of war, noted Tor Eivind Johansen, managing director of a Norwegian municipal archive group, KDRS, which is storing data in the mine.Gene banks do important work, but they are not insurance policies for the apocalypse. ![]() "By doing this now, we are ensuring that future generations will have access to this information," said Ricardo Marques, the director of the National Archives of Brazil, in a brochure announcing the Arctic World Archive. So far, three countries have started storing data in the mine, including Norway, Mexico and Brazil, which has included key documents from its national archives, among others. "For disaster recovery, all you need is a light source and some sort of digital camera and computer," the company says on its website, though it also offers a system for saving data in human-readable text or images, for "additional security". ![]() The data is digitsed and encoded on the film, with instructions on how to read the files included.
