Does all bones look the same?

There are four main types of bones: long, short, flat, and irregular. Long bones have greater length than width and consists of a shaft and a variable number of ends. They are usually somewhat curved for strength. Long bones include those in the thigh (femur), leg (tibia and fibula), arm (humerus), forearm (ulna and radius), and fingers and toes (phalanges). Short bones are somewhat cube-shaped and nearly equal in length and width. Examples of short bones include most ankle and wrist bones. Flat bones are generally thin, afford considerable protection and provide extensive surfaces for muscle attachment. Bones classified as flat bones include the cranial bones, which protect the brain; the sternum (breastbone) and ribs, which protect organs in the thorax; and the scapulae (shoulder blades). Irregular bones have complex shapes and cannot be grouped into any of the previous categories. such bones include the vertebrae of the backbone and some facial bones.

They are the result of slight changes in the genetic information that produces them.Due basically to their common ancestry. Evolution just builds on the past and does not innovate when it can tinker, So, the closer the ancestry is the closer the skeletal arrangement will be.
