I've never given such a bad review before, and I don't do so lightly, but this article is simply awful.
It gets some simple facts about ant biology wrong—such as referring to ants as "mother" and "son". This is untrue, as all ants are, in effect, siblings, sharing only a single mother in the queen. The ants labelled as mothers are clearly not queens.
It seems that the Daily Mail reporter (who, perhaps wisely, declined to receive attribution for this piece of "journalism") has little-to-no understanding of ant biology, and basically made it up as they went along, based entirely on their own interpretation of the images.
A spindly yellow ant looks bewitchingly human as she lifts her son high overhead in a game that will be familiar to any parent.
This article is hopeless. The photographs are pretty, sure; but there, the positives end. The article seeks to make us believe ants have well-developed brains capable of affection, and have things like mothers and sons playing. What nonsense!
Queen ants never leave the nest. They are the only fertile female, except when winged females are produced to start new colonies, and therefore the only "mother". Neither are ants capable of things like fun. The existance of an ant is purely a functional one.
