    "abstract": "With the number of sequenced genomes now over one hundred, and the\navailability of rough functional annotations for a substantial proportion of\ntheir genes, it has become possible to study the statistics of gene content\nacross genomes. Here I show that, for many high-level functional categories,\nthe number of genes in the category scales as a power-law in the total number\nof genes in the genome. The occurrence of such scaling laws can be explained\nwith a simple theoretical model, and this model suggests that the exponents of\nthe observed scaling laws correspond to universal constants of the evolutionary\nprocess. I discuss some consequences of these scaling laws for our\nunderstanding of organism design.",
