The evolution of morality seems to resemble more bricolage than engineering

Meanwhile, philosophy of biology (the study of living organisms, divided into many specialized fields that cover their  physiology, anatomy, behaviour, origin) ,  can inform philosophy about new and obsolete approaches in the scientific explanation of morality. 

Evolutionary ethics is not necessarily tied to adaptationism or genetic determinism. The evolution of morality seems to resemble more bricolage (do it yourself)  than engineering. 

Against stereotypical and simplified views of evolution, morality cannot be identified with a set of genes, even though genes do not necessarily lose their importance, and the question about heritable patterns remains crucial in order to define what morality is in evolution.

Evolution is a process that abounds in redundancies and imperfections, and adaptation could be a collateral effect rather than a direct optimisation. Biology is a field of potentialities, and not determinations…. Complex organisms exist thanks to imperfections, to multiplicity of use and redundancy
