Tosh entered the bridge a few minutes after the ceremony was dismissed.  He couldn't take much from it as he never really had a passion to learn the history of Earth.  He never really had a passion for any history to begin with.  He knew a little of his homeworld of Angosa and why they had left.  The man was part of a few descendants from the genetically engineered soldiers the Angosian's had developed years prior for a war they could not fight.  Originally, the Angosian's were pacifists, but that didn't prove an asset when they found themselves in a war.  In order to protect their home and future, they took drastic measures by genetically engineering their own people.  Needless to say, the process worked.  What they hadn't counted on was the fact that it would be irreversible.  It divided the people between the natural Angosians and the genetically altered soldiers.<br/><br/>His parents told him of the discrimination and segregation of their people.  It was the reason they left.  He never put much thought into learning more than that.  Now today, he came to realize that he didn't even know much about the planet he called his home.  It disturbed him a little, so when Tosh found his station upon the bridge, he spent the next hour, while waiting for the ship to disembark, searching the history of Earth for McNair's space career to learn more about it.  Perhaps it would give him a start to learning much more about the place where he had grown up.
