Are ants two-dimensional creatures? Can it sense human presence?

Whether ants are two-dimensional creatures? First of all, from the morphological structure of ants, ants are also three-dimensional three-dimensional forms. In addition, from the perspective of ants, in our impression, the direction of ants seems to be only front, back, left and right. It seems that it is impossible to perceive up and down. However, some people have done experiments where molten metal is poured into the ant's nest, and after cooling, a model of the ant's nest is formed. It can be seen from the model that the underground kingdom of ants is divided into many layers and is very three-dimensional. From this we can also conclude that ants are able to perceive the three-dimensional world.

So do ants have self-awareness?

German scientists did an experiment in which they asked ants to find food in a T-shaped maze. Under normal circumstances, ants would leave scent trails when searching for food so that other ants could follow their trails to find food, but The researchers picked up the food, creating uncertainty for the ants. At this time, the ants that went in the wrong direction had a higher probability of not leaving behind an odor trail, which the researchers said may show that the ants have the basic performance of questioning their existing cognitive abilities. If you can doubt your own life, you must be an individual with consciousness.

Ants question themselves when they experience uncertainty, and questioning is a fundamental part of cognition. In addition, this also shows that the ants will not blindly follow the smell trails left by other ants, but will correct these trails according to their own perception, and pay attention to the surrounding food, which is also the key to the survival of the ant colony.

Since ants are conscious, why can't they avoid danger?

You should find that when we get close to a group of ants, as long as we don't touch them, even if we observe for a long time, they seem to continue their work as if they didn't notice us. Even almost stepping on it, it continued its previous course like nothing. It seems to be unconscious, so why doesn't it sense risk?

Let's take a look at how ants perceive the world. From the appearance of ants, it seems that they can see two black eyes, but in fact, the commonly used sensory organs of ants are their antennae. We will find that when ants encounter food, they have two antennae constantly. When it touches the ground and encounters other ants, it also communicates with its tentacles, and its eyes, the main function may be more used to sense light, so as to distinguish whether it is in the nest or outside, day or night.

That is to say, it is not that it is not afraid, but that it does not perceive danger at all. If you touch the ants, they will also be startled and run away quickly. More often, they just need to use their antennae to sense the pheromones left by themselves or other ants to find food or go home. This is the life of ants.

Because the pheromones of ants are all left on the surface, in human eyes, it is more appropriate to describe ants as three-dimensional creatures with only two-dimensional perception ability.
