Many researchers have attempted to organize the record of human variation into an evolutionary sequence, but have failed and have not produced accepted results for a general evolutionary model. It was assumed that cultural evolution worked in the same way as biological evolution – which is false, because biological evolution works across boundaries and creates perpetually different forms of language, just like boundaries between species. create perpetually different forms of organisms. Evolutionary trends are widely considered when it comes to cultural evolution, which is akin to gradual transformations in, for example, food preferences, funerary or ritual practices, or theatrical lighting. Often, people can even create accidental – but brilliant – innovations or “mutations,” which encourage us to continue pursuing the incremental changes of cultural evolution, because it doesn't contain genes to clarify things. Studies help people understand how societies are integrated regardless of their scale, how empires rise and fall, how trade networks arise, and more. Cultural evolution is the central role in meeting the challenges of the modern world, which include social, biological aspects. and geophysical environments. It is an adaptation to an ever-changing world and environment and a frequent reminder of how culture affects human biological success.
