Saber Posted February 12, 2023 Share Posted February 12, 2023 in the world we are now the space had 3 dimensions... The majority of the animals have evolved a bilateral symmetry shape.......besides some simple creatures that have no symmetry or some other simple ones having radial symmetry In plants but the main bodies like the trunks of trees and branches again have radial symmetry or the fruits mainly have radial......but the leafs mostly have bilateral..... Also in animals those who have 3 dimensional vision have two eyes that have a large portion of each eyes field of view common with the other one and the two eyes must not me too close to each other i mean the animal needs two visions that are only slightly different from each other .....to be able to see depth and have a 3 dimensional vision Im thinking what if the world had a 4 dimensional space would the creatures in that case evolve a shape that had like three sided symmetry ? and for those animals in order to have 4 dimensional vision they needed 3 eyes located near each other * not too near not too far and all those three eyes must have a large portion of their fields in common with each other ? * Please dont laugh @ me or post mean comments if these questions is funny in your pov......

swansont Posted February 12, 2023 Share Posted February 12, 2023 Without knowing how a fourth spatial dimension would manifest itself, I don’t see how this can be answered. Link to comment Share on other sites More sharing options...

From these, the brain computes the distance. 1 Link to comment Share on other sites More sharing options...

No one is laughing at you. You have some good thoughts. One definition of a dimension is "the number of independent pieces of information (co ordinates) you need to specify the position of a point. So you need for instance one distance from 1 point in 1 dimension, two distances from two points in two dimensions, 3 distances from three points in 3 dimensions and 4 distances from 4 points in 4 dimensions. But eyes are not points, as Genady says they have visual overlap - they are two dimensional patches. This is how the brain can get the extra information requires to measure in 3 dimensions. Again but as swansont says, 4 dimensions introduces extra complications so more detail is necessary. 1 Link to comment Share on other sites More sharing options...
