Some authors provide an alternative explanation, suggesting that histologically normal melanocytes could, on the other hand, have initial mutations that do not induce proliferation (e.g., in CDKN2A or TERT promoter mutations).36,37 Moreover, other authors indicate that our knowledge of this process could be biased: the absence of nevus remnants when a melanoma is removed does not necessarily mean that the melanoma did not arise from a nevus, since the growth of the melanoma or the immune response to this could have destroyed the initial nevus remnants.36 The pathways recognized by the World Health Organization (WHO) are set out below33,38 (Table 1)
Indeed, this class is absent in cyanobacteria and a single gene, that likely represents the ancestor DHAR gene, is found in a few algae of the chlorophyceae and trebouxiophyceae classes but not in prasinophyceae
