What is an animal example of bisymmetry?
-
Why is everything you make perfectly bisymmetrical except for the practicality of its purpose?
Religions often refer to the fact that their 'God' made man to His image. But actually, we make everything to our own image. Our logic, when we are designing something lies in bisymmetry. The confusion that a 'God' made everything like we are constructing a car or a door or anything else, makes them think that everything is made to His image. A car is made bisymmetrically, but the steering wheel is (mostly) on one side (there is no need for 2 steering wheels), and so on.... . My keyboard here is not perfectly bisymmetrically designed, because my mind is slightly off from a perfectly bisymmetrical keyboard, and other functions (Num Lock,...). The more intricate a civilisation, the less bisymmetrical its equipment. In a partner we are looking for the most bisymmetrical face, but if you find one, and you mirror both sides of (in my case:her) face, you will find out her face is far from perfectly bisymmetrical, but your mind would fill out the blanks.
What are the three types of body symmetry in animals?
Radial SymmetryRadial symmetry is rotational symmetry around a fixed point known as the center. Radial symmetry can be classified as either cyclic or dihedral.Cyclic symmetries are represented with the notation Cn, where n is the number of rotations. Each rotation will have an angle of 360/n. For example, an object having C3 symmetry would have three rotations of 120 degrees.Dihedral symmetries differ from cyclic ones in that they have reflection symmetries in addition to rotational symmetry. Dihedral symmetries are represented with the notation Dn where n represents the number of rotations, as well as the number of reflection mirrors present. Each rotation angle will be equal to 360/n degrees and the angle between each mirror will be 180/n degrees. An object with D4 symmetry would have four rotations, each of 90 degrees, and four reflection mirrors, with each angle between them being 45 degrees.Bilateral SymmetryBilateral symmetry is symmetry across a line of reflection. Are people symmetric? We think we are, but upon closer analysis, we are less symmetric than we think. The more simple the creature (ants --> elephants), the more likeley it is that it will be perfectly symmetric.We took two professors, cut and pasted half of their head in Photoshop, and flipped that half horizontally. We then aligned the two halves so that it came closest ro resembling a human head. You be the judge on how good of a job we did and how symmetric people around us are in general ...Asymmetrical SymmetryAsymmetry is the absence of, or a violation of, symmetry.
