The answer is; A gopher snake occupies a burrow made by the desert rat
Commensalism involves a relationship between two organisms where one benefits while the other is unaffected. In this case, the gopher snake gets from the burrow made by the desert sake. The desert rat is unaffected (does not benefit or lose) by this action by the snake.
Mainly because of time. The precambrian era started millions of years ago, and organisms didn't have enough time to change and adapt to form new species, since this is something that takes a long time to occur.
