Proof of the theory
Examples of some species' lifecycles are now shown to display different types of spiral developmentLizards and insects
Most lizards and insects spend the main growth part of their lifecycle growing and shedding their skins. They develop within each skin until it's too tight and then they shed that skin and form a new one. Each new skin is a form change and is followed by growth within that skin. So, the main growth part of their lifecycle alternates between form change and growth.
Butterflies and moths
These insects develop thru four stages: egg, larvae, pupae and adult. They have an alternation between slow protected growth - of the type seen within most species' egg stage - and mobile, self-feeding growth stages. The egg and pupae are immobile stages where a form change slowly develops. The larvae and adult are growth stages with limited form change.
Humans and mammals
Here the alternation between stages is between reproductive stages - egg fertilization and sexually reproducing adults - and nurtured/nurturing stages - children and parents.Content copyright: Nathan Davis 2003-2013
