One manifestation of life which is not easy to comprehend is the repeated invention of linear script, first as genomic sequences, and then as language writings. Both possess their specific alphabets.
The evolution of both began, in all likelihood, from simple repetitions (TGTGTG..., GCCGCCGCC..., ma-ma-ma, da-da-da). The ontogenetic dimension arises from the fact that the spectrum of the easiest pronounced simple repetitions by babies in the period of canonical babbling is the same for all ethnicities, and, quite likely, represents the early hominids' vocal abilities.
Repetitions continued to enter, at a later point, but simultaneously accumulated mutational changes, turning into more complex words already not recognizable as repeats. This scenario appears to be common for both genome and language, which, thus, carry the heritage of the human species each in its own manner.
