%0 Journal Article %T Cryptographic Nature %A David Krakauer %J Quantitative Biology %D 2015 %I arXiv %X I consider the many ways in which evolved information-flows are restricted and metabolic resources protected and hidden -- the thesis of living phenomena as evolutionary cryptosystems. I present the information theory of secrecy systems and discuss mechanisms acquired by evolved lineages that encrypt sensitive heritable information with random keys. I explore the idea that complexity science is a cryptographic discipline as "frozen accidents", or various forms of regularized randomness, historically encrypt adaptive dynamics. %U http://arxiv.org/abs/1505.01744v1
