Laicality and secularity of Bioethics: why I believe in a biologically founded ethics

All living forms are worth of respect and of bioethical consideration as the keep promoting the DNA of the species and the preservation of its intraspecific variability. However, the ethical consideration varies and has a different weight according to different biological complexity and its ontogenetic cycle.A first hierarchical level of value must be attributed to the specific DNA of a biological entity characterised by a haploid order of genes such as those of a bacterium, a gamete, a spore or an haplophte.The second hierarchical level leading to complexity in the history of life are the diploid entityies, characterised by a diploid order of genes. The differ from the haploid because the fusion of the two haploid DNA filaments presupposes meiosis, which functions as a selective filter of casual mutations, the majority of which lead to the extinction of the haploid entity.The third ethical level of complexit concern those animal species in which the concept of individual is present; individual being defi..
