The Iggy (the Iguana) and Itchy (the Ichthyosaurus) have evolutionary similarities. Itchy is created from soft tissue, which has been preserved for millennia. Iggy is one offspring from a female Iguana and the two are incubated in the female. The birth goes according to plan and the two become mates. This generates a completely new development of life. as the rest of the civilised world collapses the creatures and the flora and fauna thrive. The earth reverts to its ancient past in harmony.
