Abstract

The topic of vitamin D is studied in relation to elements of human evolutionary biology and prehistory. Due to the evolution of hairlessness and the requirement for effective ecrine sweat production for cooling, cutaneous pigmentation was developed to protect the skin from ultraviolet harm. As people moved to northern latitudes, their colouring started to deteriorate. As additional dispersal took place over the world, their growing technological skill surpassed evolution’s limiting rate. A date for the evolution of warm-weather clothes and the subsequent protection from ultraviolet light, which reduced vitamin D synthesis, can be deduced from research on human louse mutations. Because life evolves, biological technologies are inherently distinct from all others. Therefore, new design techniques with evolution at their core are needed for bioengineering. Ad hoc biosystem design now makes use of evolution knowledge. We will not be able to fully exploit evolution’s potential as an engineering tool or comprehend or control its unintended repercussions for our biological designs unless we have an engineering theory of evolution. Here, we suggest the evotype as a practical idea for designing the evolution of bio systems or other self-adaptive technologies, potentially outside the scope of biology.
