independent countries who sought to become more developed—a model of progress and industrialization which was itself a form of sociocultural evolution. Technological perspectives Many argue that the next stage of sociocultural evolution consists of a merger with technology, especially information processing technology. Several cumulative major transitions of evolution have transformed life through key innovations in information storage and replication, including RNA, DNA, multicellularity, and also language and culture as inter-human information processing systems. in this sense it can be argued that the carbon-based biosphere has generated a cognitive system (humans) capable of creating technology that will result in a comparable evolutionary transition. "Digital information has reached a similar magnitude to information in the biosphere. It increases exponentially, exhibits high-fidelity replication, evolves through differential fitness, is expressed through artificial intelligence (AI), and has facility for virtually limitless recombination. Like previous evolutionary transitions, the potential symbiosis between biological and digital information will reach a critical point where these codes could compete via natural selection. Alternatively, this fusion could create a higher-level superorganism employing a low-conflict division of labor in performing informational tasks...humans already embrace fusions of biology and technology. We spend most of our waking time communicating through digitally mediated channels, ...most transactions on the stock market are executed by automated trading algorithms, and our electric grids are in the hands of artificial intelligence. With one in three marriages in America beginning online, digital algorithms are also taking a role in human pair bonding and reproduction". Anthropological perspectives Current political theories of the new tribalists consciously mimic ecology and the life-ways of indigenous peoples, augmenting them with modern sciences. Ecoregional Democracy attempts to confine the "shifting groups", or tribes, within "more or less clear boundaries" that a society inherits from the surrounding ecology, to the borders of a naturally occurring ecoregion. Progress can proceed by competition between but not within tribes, and it is limited by ecological borders or by Natural Capitalism incentives which attempt to mimic the pressure of natural selection on a human society by forcing it to adapt consciously to scarce energy or materials. Gaians argue that societies evolve deterministically to play a role in the ecology of their biosphere, or else die off as failures due to competition from more efficient societies exploiting nature's leverage. Thus, some have appealed to theories of sociocultural evolution to assert that optimizing the ecology and the social harmony of closely knit groups
