We are all unique, and when I say all, I am not referring only to human beings, nor only to animals, nor only to all living beings (plants and animals), but also to things of the mineral kingdom. Among these, one of the most cited examples is that no two snowflakes are the same.
These are just some of the infinite designs that a snowflake can take to form.
But if we go a little further, we will realize that no two stones are the same.
Not even two equal grains of sand.
Here the differences are already measured in tenths or hundredths of a millimeter
In the plant kingdom, we can find trees of the same family but we will not find two that are the same. They will be differentiated by their height, the arrangement of their branches, the color of their trunk, the spots on it, their number of leaves and many more characteristics.
Trees of the same family
And speaking of the leaves, the differences are more subtle but they exist: their length, thickness, color, spots, the pattern of their veins. Here we already have to talk about millimeters or tenths of a millimeter.
The same thing happens with animals.
At first glance, the puppies seem identical, but it is enough to see the white spot between their eyes to realize that they are different
There are other animals in which it is more difficult to see the differences but they exist.
A group of white ducks
Even ants are unique too. Here the differences are already measured in hundredths or thousandths of a millimeter (microns).
And microbes are not spared from this. In the photo we can see that they differ by their length, thickness, number and shape of the folds on their bodies and other characteristics.
And what about us human beings? We can more easily see how different we are.
But what about the twins? They also have small differences that are imperceptible to the naked eye, but it should be mentioned that their fingerprints are different, even if they are twins.
Twin girls. It can be seen that the little girl on the right has her central incisor teeth a little further apart than her little sister’s
