This was explained by Darwin's evolution theory, we are all descendants of just one single species, and because of that, all species have something in common between them.
That's why there's a possibility that a human gene can correct a defective gene in a yeast cell. Although this could really happen, we are not sure about it, it's a possibility, don't always be sure of something in biology, there's always more to understand and to learn.
