Radial symmetry occurs when the parts of an animal or object are arranged around a central axis, and if they are divided through that axis they create equal parts on either side. ... Chordates, including humans, are also all classified as having bilateral symmetry and can be divided into a left and right side.

The position also allows the hands to look nice on the face of the timepiece. The 10:10 position is symmetrical, and the human brain tends to appreciate symmetry and orderliness. Another reason is that key details on the face of the watch or clock usually remain visible at 10:10.

At the same time, humans are overwhelmingly right-handed when it comes to tool making compared to other species. This is most likely because the left and right hemispheres control motor action on the opposite sides of the body.

While studies employing the composite faces produced results that indicate that more symmetrical faces are perceived as more attractive, studies applying the face-half mirroring technique have indicated that humans prefer slight asymmetry.

Body Symmetry of Phylum Chordata Although chordates come in many shapes and sizes, they share the four characteristics listed above and they also all have bilateral symmetry. If you divide a chordate in half, you will get two equal pieces that are mirror images of each other.

The trait appears to be genetic and is a result of variation in collagen, the main structural protein of connective tissue. Being double-jointed has long been linked with an increased risk for asthma and irritable bowel syndrome, among other physical disorders.

Radial symmetry and bilateral symmetry are two different types of biological symmetries found in organisms. ... The key difference between radial and bilateral symmetry is that radial symmetry generates identical body halves around the central axis whereas bilateral symmetry generates only two sides as left and right.

Mirror image identical twins have reverse asymmetric features. ... According to About.com, "they may be right- and left-handed, have birthmarks on opposite sides of their body, or have hair whorls that swirl in opposite directions." This occurs when the twins split from one fertilized egg more than a week after conception.

Animals with bilateral symmetry produce a third layer in-between called mesoderm, making them triploblastic. Germ layers will eventually give rise to all of an animal's tissues and organs through a process called organogenesis.
