Eyes'" are organs that detect light, and send signals along the optic nerve to the visual and other areas of the brain. Complex optical systems with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system. Image-resolving eyes are present in cnidaria, mollusks, chordates, annelids and arthropods. The simplest "eyes", in even unicellular organisms, do nothing but detect whether the surroundings are light or dark, which is sufficient for the entrainment of circadian rhythms. From more complex eyes, retinal photosensitive ganglion cells send signals along the retinohypothalamic tract to the suprachiasmatic nuclei to effect circadian adjustment. Overview. Complex eyes can distinguish shapes and colors. The visual fields of many organisms, especially predators, involve large areas of binocular vision to improve depth perception; in other organisms, eyes are located so as to maximise the field of view, such as in rabbits and horses. The first proto-eyes evolved among animals 540 million years ago, about the time of the so-called Cambrian explosion. The last common ancestor of animals possessed the biochemical toolkit necessary for vision, and more advanced eyes have evolved in 96% of animal species in 6 of the thirty-something main phyla. In most vertebrates and some mollusks, the eye works by allowing light to enter it and project onto a light-sensitive panel of cells, known as the retina, at the rear of the eye. The cone cells (for color) and the rod cells (for low-light contrasts) in the retina detect and convert light into neural signals for vision. The visual signals are then transmitted to the brain via the optic nerve. Such eyes are typically roughly spherical, filled with a transparent gel-like substance called the vitreous humour, with a focusing lens and often an iris; the relaxing or tightening of the muscles around the iris change the size of the pupil, thereby regulating the amount of light that enters the eye, and reducing aberrations when there is enough light. The eyes of cephalopods, fish, amphibians and snakes usually have fixed lens shapes, and focusing vision is achieved by telescoping the lens similar to how a camera focuses. Compound eyes are found among the arthropods and are composed of many simple facets which, depending on the details of anatomy, may give either a single pixelated image or multiple images, per eye. Each sensor has its own lens and photosensitive cell(s). Some eyes have up to 28,000 such sensors, which are arranged hexagonally, and which can give a full 360-degree field of vision. Compound eyes are very sensitive to motion. Some arthropods, including many Strepsiptera, have compound eyes of only a few facets, each with a retina capable of creating an image, creating vision. With each eye viewing a different thing, a fused image from all the eyes is produced in the brain, providing very different, high-resolution images. Possessing detailed hyperspectral color vision, the Mantis shrimp has been reported to have the world's most complex color vision system. Trilobites, which are now extinct, had unique compound eyes. They used clear calcite crystals to form the lenses of their eyes. In this, they differ from most other arthropods, which have soft eyes. The number of lenses in such an eye varied, however: some trilobites had only one, and some had thousands of lenses in one eye. In contrast to compound eyes, simple eyes are those that have a single lens. For example, jumping spiders have a large pair of simple eyes with a narrow field of view, supported by an array of other, smaller eyes for peripheral vision. Some insect larvae, like caterpillars, have a different type of simple eye (stemmata) which gives a rough image. Some of the simplest eyes, called ocelli, can be found in animals like some of the snails, which cannot actually "see" in the normal sense. They do have photosensitive cells, but no lens and no other means of projecting an image onto these cells. They can distinguish between light and dark, but no more. This enables snails to keep out of direct sunlight. In organisms dwelling near deep-sea vents, compound eyes have been secondarily simplified and adapted to A skirt'" is a tube- or cone-shaped garment that hangs from the waist and covers all or part of the legs. In European culture, skirts are usually considered women's clothing. However, there are exceptions. The kilt is a traditional men's garment in Scotland, and some fashion designers, such as Jean-Paul Gaultier, have shown men's skirts. At its simplest, a skirt can be a draped garment made out of a single piece of material (such as pareos), but most skirts are fitted to the body at the waist and fuller below, with the fullness introduced by means of dart, gores, pleats, or panels. Modern skirts are usually made of light to mid-weight fabrics, such as denim, jersey, worsted, or poplin. Skirts of thin or clingy fabrics are often worn with slips to make the material of the skirt drape better and for modesty. The hemline of skirts can be as high as the upper thigh or as low as the ground, depending on the whims of fashion and the modesty or personal taste of the wearer. Some medieval upper-class women wore skirts over 3 metres in diameter at the bottom. At the other extreme, the miniskirts of the 1960s were minimal garments that may have barely covered the underwear when seated. Costume historians typically use the word "petticoat" to describe skirt-like garments of the 18th century or earlier. History. Skirts have been worn by men and women from many cultures, such as the lungi, kanga and sarong worn in South Asia and Southeast Asia, and the kilt worn in Scotland. The earliest known culture to have females wear miniskirts were the Duan Qun Miao, which literally meant "short skirt Miao" in Chinese. This was in reference to the short miniskirts "that barely cover the buttocks" worn by women of the tribe, and which were "probably shocking" to Han Chinese observers in medieval and early modern times. Skirts in the 19th century. During the nineteenth century the cut of women's dresses in western culture varied more widely than in any other century. Waistlines started just below the bust (the Empire silhouette) and gradually sank to the natural waist. Skirts started fairly narrow and increased dramatically to the hoopskirt and crinoline-supported styles of the 1860s; then fullness was draped and drawn to the back by means of bustles. Skirts in the 20th and 21st centuries. Beginning around 1915, hemlines for daytime dresses left the floor for good. For the next fifty years fashionable skirts became short (1920s). then long (1930s), then shorter (the War Years with their restrictions on fabric), then long (the New Look), then shortest of all during the 1960s, when skirts became as short as possible while avoiding exposure of underwear, which was considered taboo. Since the 1970s and the rise of pants for women as an option for all but the most formal of occasions, no one skirt length has dominated fashion for long, with short and ankle-length styles often appearing side-by-side in fashion magazines and catalogs. Male wear. There are a number of male garments which fall under the catergory of "skirt" or "dress." These go by a variety of names and form part of the traditional dress for men from various cultures. Usage varies- the dhoti is part of everyday dress on the Indian subcontinent while the kilt is more usually restricted to occasional wear and the foustanella is used almost exclusively as costume. Robes, which are a type of dress for men, have existed in many cultures, including the Japanese kimono, the Chinese cheongsam, the Arabic thobe, and the African Senegalese kaftan. Robes are also used in some religious orders, such as the cassock in Christianity and various robes and cloaks that may be used in pagan rituals. Examples of men's skirts and skirt like garments from various cultures include: In the Western world skirts, dresses and similar garments are considered primarily women's clothing today although historically that was not the case. The wearing of skirts by men in these areas is generally seen as cross-dressing although some fashion designers such as Jean-Paul Gaultier have produced skirts for men and kilts are widely accepted in some situations.
