Biomod
The discovery of Long John has made alteration of the human genome easier than ever before. Although mankind has been altering his genetic makeup since the early years of the 21st Century, Long John or xenosilicate has allowed sophistication of the process to an unprecedented degree.
Bio-modification has created huge diversity in the species, effectively becoming tailored evolution, allowing mankind to survive in places previously hostile to this fragile species.
Biomods come in a variety of forms, from medical applications, allowing regeneration of damaged limbs & vital organs, to complete personality changes.
On Poseidon, Biomods are commonplace, enabling humans to adapt more readily to salinated water, venomous organisms and other environmental hazards. A boimod is available for almost every purpose, from endocrine control to increased haemoglobin affinity for oxygen.
Perhaps the most important and far-reaching application of xenosilicates Long John (at least in human terms) is longevity therapy, a treatment on the genetic level, arresting the ageing process. The 'Fountain of Youth' is no longer a mythological concept.
