The medical community had recorded some cases that were likely this disorder as far back as the 1800's. It was described as a disease that causes people to "turn into stone". It became more well known in the 1970's with the treatment and eventual death of a patient with the extremely rare genetic disorder who donated his body to science. The gene that causes the progressive ossification of soft tissue to bone, was identified in 2006. It is called FOP disease because the medical name is Fibrodysplasia Ossificans Progressiva. For more information from WikiPedia on FOP, see the related links section below.

The two main parts of the integumentary system is the epidermis and the dermis. There are also a number of accessory parts such as hair, glands, nerve receptors, etc. The functions of the integumentary system are mostly to protect the underlying tissues but also aids in heat regulation, waste excretion, and vitamin D production.

The integumenatry system is the organ system that contains the skin, hair, nails, sweat glands, and oil glands, as well as the skin appendages (including hair, scales, feathers, hoofs, and nails).. Skin is the largest organ in the body. The integumentary system has a variety of functions; it may serve to waterproof, cushion, and protect the deeper tissues, excrete wastes, and regulate temperature, and is the attachment site for sensory receptors to detect pain, sensation, pressure, and temperature. In most terrestrial vertebrates with significant exposure to sunlight, the integumentary system also provides for vitamin D synthesis.

Pigmentation in you skin is determined by the amount of melanin given to you by your parents, in other words genetics.

Acually, they only partially have one. You see, they have an inner epidermis, but not an outer one. The epidermis acually was not the purpose to protect the plant in the first place!
