  The term ‘life’ is important outside of biology. Often, the focus is not on the concept of life or life in general, but on the status of individual living entities. Typically, the focus is on the beginning and end stages of individual lives, which raises legal, religious, and moral questions. The start of an individual life has been the source of contraception and abortion discussions  (Noonan 1967, Dellapenna 1978). Unfortunately, developmental biology does not provide an uncontroversial starting point for when ‘life’ begins (Maienschein 2014). The end of individual lives was also a heated debate in the 20th century as new technologies were able to keep human bodies alive long after they would have died in nature (DeGrazia 2016).
