| Sea silk Sea silk is an extremely fine, rare and valuable fabric produced from the long silky filaments or byssus secreted by a gland in the foot of several bivalve mollusks (particularly Pinna nobilis L.) by which they attach themselves to the sea bed.Sea silk was produced in the Mediterranean region from the large bivalve mollusk, Pinna nobilis, until early in the 20th century.

| Origin of the domestic dog The origin of the domestic dog began with the domestication of the dog (Canis lupus familiaris) from the gray wolf (Canis lupus) several tens of thousands of years ago. Domesticated dogs provided early humans with a guard animal, a source of food and fur, and a beast of burden. The process continues to this day, as the intentional cross-breeding of dogs continue, to create the so called "designer dogs". Origin_of_the_domestic_dog | |
| Ronald J. Clarke Ronald J. Clarke is an paleoanthropologist most notable for the discovery of "Little Foot", an extraordinary complete skeleton of Australopithecus, in the Sterkfontein Caves. . A more technical description of various aspects of his description of the Australopithecus skeleon was published in the Journal of Quaternary Science,He also discovered the Homo ergaster partial cranium SK 847.. He also played a role in the discovery of a new skeleton of Homo habilis related to Homo rudolphensus Ronald_J._Clarke | |
| Paper cup paper cup is a disposable cup made out of paper and often lined with plastic or wax to prevent liquid from leaking out or soaking through the paper. It may be made of recycled paper and is widely used around the world. Paper_cup | |
| 15 and 290 theorems 15 theorem of John H. Conway and W. A. Schneeberger (Conway-Schneeberger Fifteen Theorem), proved in 1993, states that if an integral quadratic form with integral matrix represents all positive integers up to 15, then it represents all positive integers. (All quadratic forms in this article are implicitly assumed to be positive definite.) The proof was complicated, and was never published. Manjul Bhargava found a much simpler proof which was published in 2000. 15_and_290_theorems | |
| Ventastega Ventastega was a Tiktaalik-like tetrapodomorph that lived during the Famennian subdivision of the Late Devonian period approximately 374.5 to 359.2 million years ago, though Ventastega origins as a tetrapod lineage are probably seated in the preceding Frasnian period of the Late Devonian (385.3 to 374.5 million years ago) when a surge of morphological diversification of tetrapods began.

| Tritare A tritare is a guitar (invented in 2003 by Samuel Gaudet and Claude Gauthier of the University of Moncton) of a family of stringed instruments which use Y-shaped strings, instead of the usual string-shaped strings; Y-shaped strings can produce sounds which are harmonic integer multiples, but also nonharmonic sounds more akin to those produced by percussion instruments.

| Artificial sunlight Artificial sunlight is the use of a light source to simulate sunlight where the unique benefits of sunlight are needed, but where sufficient natural sunlight is not available or is not feasible. The concept has various applications including greenhouse lighting, tanning of skin, light therapy and even in refrigerators to preserve the freshness of vegetables. A light source used to simulate the sunlight would be known as a solar simulator. Artificial_sunlight | |
| Penis fencing Penis fencing is a mating behavior engaged in by certain species of flatworm, such as Pseudobiceros hancockanus. Species which engage in the practice are hermaphroditic, possessing both eggs and sperm-producing testes.The species "fence" using two-headed dagger-like penises which are pointed, and white in color. The "winner" is the organism that inseminates the other. The sperm is absorbed through pores in the skin, causing fertilization in the "loser". Penis_fencing | |

| Parasitic plant parasitic plant is one that derives some or all of its sustenance from another plant. About 4,100 species in approximately 19 families of flowering plants are known. Parasitic plants have a modified root, the haustorium, that penetrates the host plant and connects to the xylem, phloem, or both. Parasitic_plant | |

| Spanish Inquisition The Spanish Inquisition was an ecclesiastical tribunal started in 1478 by Catholic Monarchs Ferdinand II of Aragon and Isabella I of Castile. It was intended to maintain Catholic orthodoxy in their kingdoms, and to replace the medieval inquisition which was under papal control. The new body was under the direct control of the Spanish monarchy. It was not definitively abolished until 1834, during the reign of Isabella II. Spanish_Inquisition | |

| Cactus Hill Cactus Hill is an archaeological site in the U.S. state of Virginia. It lies in the southeastern part of the state on the Nottoway River roughly 45 miles south of Richmond. The site, owned by the International Paper Corporation, is situated on sand dunes above the river.The site has yielded multiple levels of early occupation. Cactus_Hill | |
| David Reich (geneticist) David Reich is a geneticist and professor in the department of genetics at the Harvard Medical School, and an associate of the Broad Institute, whose research studies comparing human DNA with that of chimpanzees has generated controversy. Dr. Reich's genetics research focuses primarily on finding complex genetic patterns that cause susceptibility to common diseases among large populations, rather than finding specific genetic flaws associated with relatively rare illnesses.
