The Green Hell Question

The Green Hell Question is why Green Hell's biosphere is so different from all others known by the Union. Most biospheres can trace all life native to them to one source.

While there has been years of study on hundreds of species on Green Hell, that study has only reinforced the concept that a lot more is not known about the life forms native to that planet than is known.

There are two parts to the Green Hell Question. It's thought that discovering the answer to those two questions will bring great advances in the biological sciences.
 * Why does it appear to be so many diverse independent evolutionary threads?
 * What caused the majority of those evolutionary processes to result in dangerous to very dangerous lifeforms?
