Question

If the point of reproduction is to pass your DNA to the next generation, why do some organisms such as ants, bees, or termites produce thousands of individuals that have no chance of reproducing? This seems to me to be a terrible waste energy. The queen basically becomes a helpless baby factory, unable to care for her own young, find food or even leave the nest in many cases. So she must expend even more energy to produce workers to care for her young and herself. This seems to me to be a huge evolutionary DISadvantage, But it worked because there are several different organisms that do this.

Explanation / Answer

In some species of ants, there are workers that are completely sterile although in many species of ants, bees and termites, the workers can actually reproduce a bit, but not as much as the queen. This posed a problem for Darwin when he was thinking about evolution by natural selection because usually, evolution should move individuals towards the best chance of passing on their own genes directly to the next generation.  Obviously, sterile worker ants can't do that. But they are, of course, very closely related to the queen who is their mother, and actually, because of ant genetics, they're more closely related genetically to their mother than we are to our own mothers, because ant genetics work slightly differently. So, this means that their genes will be passed on to the next generation through their siblings, through their sisters, the future queens of other colonies, and through the males that that colony produces.
