"In a strange way, therefore, a key aspect of preformation and pre-existence lives on the overstated claims of genetics determinism. This simplistic understanding of the role of genes is shared by those scientists who do not realise the complexity of living systems, or who underestimate the essential role of interactions with the environment, which affect every aspect of the activity and hrowth of organisms. Twenty first- century geneticista who suggest that there is astraight line running from a single DNA sequence to a complex humanbehavioural trait, or even something as simple as afinger, would be amazed to knowthat they are the modern equivalents of the seventeenth- and eighteenth-century thinkers who advocated a rigid and literal form of preformation."
