Many scholars 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. Cultural evolution was assumed to work the same way as biological evolution – which is false, because biological evolution works through boundaries that create perpetually different forms of language, just as species boundaries create perpetually different forms of organisms . Evolutionary trends are much taken into account when it comes to cultural evolution, which is similar to gradual transformations in, for example, food preferences, burial or ritual practices, or theatrical lighting. Often people can even create accidental – but brilliant – innovations or “mutations”, which encourage us to continue looking for gradual changes in cultural evolution, since it contains no genes to clarify things. The studies help people understand how societies are integrated, regardless of size, how empires rise and fall, how trade networks arise, etc. Cultural evolution is the central role that addresses the challenges of the modern world, which includes social, biological and geophysical environments. It is an adaptation to the constantly changing world and environment and is a frequent reminder of how culture affects the biological success of human beings
