However, if you violently shake the jar and dump them back on the ground the ants will fight until they eventually kill each other. The thing is, the red ants think the black ants are the enemy and vice versa, when in reality, the real enemy is the person who shook the jar. This is exactly what's happening in society today. The real question we need to be asking ourselves is who's shaking the jar… and why?"

The above observation by Shera Starr cannot be improved upon.

And yet, the answer to the question is fairly simple.

But let's first take a look at this anomaly. It's natural to identify with some individuals more than others. That tendency occurred before Homo sapiens came into being. In addition, the tendency for animals to group into families or packs also predates humans.

We tend to want to be around those who behave the way we do and have the same perceptions as we do. That only makes sense. We wish to surround ourselves with those who are unlikely to surprise and possibly even endanger us by behaving in a fashion that we would not ourselves choose.

This is the basis of trust – an essential in group or herd mentality. And being a part of a group or herd brings to us increased safety.

So, what then, of those who are not within our group or herd? How do we relate to them?

Well, any nature programme that covers animals gathered around a water hole can provide that answer.

We see a small group of wild pigs drinking alongside a group of wildebeests. Neither species is predatory, so they learn to recognise that, even though one group is made up of savannah-living grazers and the other are forest-living foragers, they can easily co-exist, which will increase the ability of both species to use the water hole at the same time.

We might also see a group of hyenas using the water hole, but we notice that the prey animals all seek to keep a distance between themselves and the predatory hyenas. Everyone understands that they are all at the water hole for the same reason and it makes sense to share, even if, in another situation, they are natural enemies.
