The paper tree has been developed to reduce production costs and loss of tree life in the paper manufacturing industry. The recent explosion in popularity of recycled paper products lead a Swiss based company to develop a tree which grows square leaves that, when dried, are already usable as writing paper. In the image above we see a company employee holding a dried leaf beside the trunk of one of the many Paper Trees now grown by the company.

The fern spider is unique on this list as it is the only combined plant and animal. At the time of writing this is the only animal that has successfully been crossed with a plant. The spider is a cross between a common Italian Wolf spider (Lycosa tarantula) and the ponga fern (Cyathea dealbata). The purpose of this bizarre crossbreed was to study the survival rates of spiders with built in camouflage versus those without in a series of studies on Natural Selection at Massey University in New Zealand. The results of the study have not been published yet.
