The accounts of the emergence of life within the universe vary in description, but classically the deity called Brahma, from a Trimurti of three deities also including Vishnu and Shiva, is described as performing the act of 'creation', or more specifically of 'propagating life within the universe' with the other two deities being responsible for 'preservation' and 'destruction' (of the universe) respectively. In this respect some Hindu schools do not treat the scriptural creation myth literally and often the creation stories themselves do not go into specific detail, thus leaving open the possibility of incorporating at least some theories in support of evolution. Some Hindus find support for, or foreshadowing of evolutionary ideas in scriptures, namely the Vedas.
