The Bio Overseer's thoughts

"Ah, good! We have another one, and this one shows even more promise!" the bio overseer said to himself as he watched the scientists examine the specimen of the hybrid species that they had developed long before.  It has only been a small fraction more than twenty million years since we developed this hybrid."

"They were perfectly compatible with the planet, much more so than we were.  For centuries, they served us well.  They were excellent resource collectors, and now I see now that they have begun to evolve again.  Such a short amount of time, and some of them have already shown biological compatibility." the overseer said.

"Despite their greed, prejudices, and other shortcomings, this sub-species may be what we need.  It has been some time, but I believe that their molecular structures shall serve us again!" he said as he watched.

When the primary search vessels discovered the somewhat toxic planet, it was considered just another planet with primitive life.  When the vast amount of resources were discovered by chance, the small planet became the focus of a newly developed collection project.

The visitors quickly discovered the toxicity of the planet to their biology, and developed special protective clothing for their workers.  Over time, conflict arose from the working classes over the fact that they no longer wanted to perform the dangerous work of stripping the planet of valuable resources.  This led to bloodshed between the working class, who had become wealthy, and those who benefitted from their work.

In the end, it was agreed that a new native species would be developed with a contribution of the visitor's own genetics, to produce a hybrid that would be better adapted to the planet itself, be intelligent, and would become a slave species that would perform the menial and dangerous work of mining valuable resources.

"Soon, the time will come when these creatures will serve us again," the bio overseer whispered to himself, "soon we will collect the better evolved ones, re-engineer them and produce a variety of species.  They shall be specialized for mining various planets, and they shall be compatible with their new environments."

"Such is our way of ever expanding our kind across the universe, and using the resources of the universe in order to do so!"
