Phys.Org (Nov. 14) -- A new study by two Illinois researchers has demonstrated that dynamic elements within the human genome interact with each other in a way that strongly resembles the patterns seen in populations of predators and prey. The findings, published in Physical Review Letters by physicists Chi Xue and Nigel Goldenfeld, are an important step toward understanding the complex ways that genomes change over the lifetime of individual organisms, and how they evolve over generations.
