Title: Mammal
Context: Recent molecular phylogenetic studies suggest that most placental orders diverged about 100 to 85 million years ago and that modern families appeared in the period from the late Eocene through the Miocene. But paleontologists object that no placental fossils have been found from before the end of the Cretaceous. The earliest undisputed fossils of placentals come from the early Paleocene, after the extinction of the dinosaurs. In particular, scientists have recently identified an early Paleocene animal named Protungulatum donnae as one of the first placental mammals. The earliest known ancestor of primates is Archicebus achilles from around 55 million years ago. This tiny primate weighed 20–30 grams (0.7–1.1 ounce) and could fit within a human palm.

Title: Mammal
Context: The earliest clear evidence of hair or fur is in fossils of Castorocauda, from 164 million years ago in the Middle Jurassic. In the 1950s, it was suggested that the foramina (passages) in the maxillae and premaxillae (bones in the front of the upper jaw) of cynodonts were channels which supplied blood vessels and nerves to vibrissae (whiskers) and so were evidence of hair or fur; it was soon pointed out, however, that foramina do not necessarily show that an animal had vibrissae, as the modern lizard Tupinambis has foramina that are almost identical to those found in the nonmammalian cynodont Thrinaxodon. Popular sources, nevertheless, continue to attribute whiskers to Thrinaxodon.

question: When is it believed that the earliest know hair was said to exist? 

answer: 164 million years ago

question: When was it suggested that foramina premaxillae could contain the first know hairs? 

answer: 1950s

question: Which major time period were these suggested hairs from? 

answer: Jurassic
Title: Mammal
Context: When endothermy first appeared in the evolution of mammals is uncertain. Modern monotremes have lower body temperatures and more variable metabolic rates than marsupials and placentals, but there is evidence that some of their ancestors, perhaps including ancestors of the therians, may have had body temperatures like those of modern therians. Some of the evidence found so far suggests that Triassic cynodonts had fairly high metabolic rates, but it is not conclusive. For small animals, an insulative covering like fur is necessary for the maintenance of a high and stable body temperature.

question: Which group of animal has a lower body temperature that marsupials and placentals? 

answer: monotremes

question: Which time period is suggested that cynodonts had a high metabolic rate? 

answer: Triassic

question: Why is it necessary for smaller animals to have an insulative covering? 

answer: maintenance of a high and stable body temperature
Title: Mammal
Context: Breathing is largely driven by the muscular diaphragm, which divides the thorax from the abdominal cavity, forming a dome with its convexity towards the thorax. Contraction of the diaphragm flattens the dome, increasing the volume of the cavity in which the lung is enclosed. Air enters through the oral and nasal cavities; it flows through the larynx, trachea and bronchi and expands the alveoli. Relaxation of the diaphragm has the opposite effect, passively recoiling during normal breathing. During exercise, the abdominal wall contracts, increasing visceral pressure on the diaphragm, thus forcing the air out more quickly and forcefully. The rib cage itself also is able to expand and contract the thoracic cavity to some degree, through the action of other respiratory and accessory respiratory muscles. As a result, air is sucked into or expelled out of the lungs, always moving down its pressure gradient. This type of lung is known as a bellows lung as it resembles a blacksmith's bellows. Mammals take oxygen into their lungs, and discard carbon dioxide.

question: When air enters both the oral and nasal cavities, where does it flow through? 

answer: larynx, trachea and bronchi

question: Increasing pressure on the diaphragm thus increasing air output more frequently is usually caused by? 

answer: exercise

question: A result of air being sucked into or blown out of the lung thats moving its pressure gradient is referred to? 

answer: bellows lung

question: Where did the term Bellows Lung come from? 

answer: blacksmith's bellows
Title: Mammal
Context: The epidermis is typically 10 to 30 cells thick; its main function is to provide a waterproof layer. Its outermost cells are constantly lost; its bottommost cells are constantly dividing and pushing upward. The middle layer, the dermis, is 15 to 40 times thicker than the epidermis. The dermis is made up of many components, such as bony structures and blood vessels. The hypodermis is made up of adipose tissue. Its job is to store lipids, and to provide cushioning and insulation. The thickness of this layer varies widely from species to species.

answer: 10 to 30 cells thick

question: What is the main function of the epidermis? 

answer: to provide a waterproof layer

question: How much more thicker is the dermis to the epidermis? 

answer: 15 to 40 times thicker

question: What is the dermis mainly consist of? 

answer: bony structures and blood vessels

question: What does the Hyperdermis consist of? 

answer: adipose tissue
Title: Mammal
Context: Mammalian hair, also known as pelage, can vary in color between populations, organisms within a population, and even on the individual organism. Light-dark color variation is common in the mammalian taxa. Sometimes, this color variation is determined by age variation, however, in other cases, it is determined by other factors. Selective pressures, such as ecological interactions with other populations or environmental conditions, often lead to the variation in mammalian coloration. These selective pressures favor certain colors in order to increase survival. Camouflage is thought to be a major selection pressure shaping coloration in mammals, although there is also evidence that sexual selection, communication, and physiological processes may influence the evolution of coloration as well. Camouflage is the most predominant mechanism for color variation, as it aids in the concealment of the organisms from predators or from their prey. Coat color can also be for intraspecies communication such as warning members of their species about predators, indicating health for reproductive purposes, communicating between mother and young, and intimidating predators. Studies have shown that in some cases, differences in female and male coat color could indicate information nutrition and hormone levels, which are important in the mate selection process. One final mechanism for coat color variation is physiological response purposes, such as temperature regulation in tropical or arctic environments. Although much has been observed about color variation, much of the genetic that link coat color to genes is still unknown. The genetic sites where pigmentation genes are found are known to affect phenotype by: 1) altering the spatial distribution of pigmentation of the hairs, and 2) altering the density and distribution of the hairs. Quantitative trait mapping is being used to better understand the distribution of loci responsible for pigmentation variation. However, although the genetic sites are known, there is still much to learn about how these genes are expressed.

question: What is another name used for mammalian hair? 

answer: pelage

question: Which color of hair is most common among mammalian taxa? 

answer: Light-dark color

question: Besides Camouflage being a reason for having certain hair colors, what other reasons have been discovered?  

answer: sexual selection, communication, and physiological processes
Title: Mammal
Context: Most mammals are viviparous, giving birth to live young. However, the five species of monotreme, the platypuses and the echidnas, lay eggs. The monotremes have a sex determination system different from that of most other mammals. In particular, the sex chromosomes of a platypus are more like those of a chicken than those of a therian mammal. Like marsupials and most other mammals, monotreme young are larval and fetus-like, as the presence of epipubic bones prevents the expansion of the torso, forcing them to produce small young.

question: What is the common mammal group that gives birth to live young? 

answer: viviparous

question: How many species of mammals lay eggs? 

answer: five species

question: Which mammal that has the bill of a duck lays eggs? 

answer: platypus

question: The platypus has sex chromosomes more related to which other non-mammal? 

answer: chicken
Title: Mammal
Context: Viviparous mammals are in the subclass Theria; those living today are in the marsupial and placental infraclasses. A marsupial has a short gestation period, typically shorter than its estrous cycle, and gives birth to an undeveloped newborn that then undergoes further development; in many species, this takes place within a pouch-like sac, the marsupium, located in the front of the mother's abdomen. This is the plesyomorphic condition among viviparous mammals; the presence of epipubic bones in all non-placental mammals prevents the expansion of the torso needed for full pregnancy. Even non-placental eutherians probably reproduced this way.

question: Which sub class are most viviparous mammals in? 

answer: Theria

question: Viviparous mammals today are in which two main infraclasses? 

answer: marsupial and placental

question: What is present in all non-placental mammals? 

answer: epipubic bones
Title: Mammal
Context: In intelligent mammals, such as primates, the cerebrum is larger relative to the rest of the brain. Intelligence itself is not easy to define, but indications of intelligence include the ability to learn, matched with behavioral flexibility. Rats, for example, are considered to be highly intelligent, as they can learn and perform new tasks, an ability that may be important when they first colonize a fresh habitat. In some mammals, food gathering appears to be related to intelligence: a deer feeding on plants has a brain smaller than a cat, which must think to outwit its prey.

question: Which part is larger relative to the brain in primates? 

answer: cerebrum

question: Which non-primate has the ability to learn and perform new task? 

answer: Rats

question: Mammals with smaller brains tend to be in what class in the food chain? 

answer: prey
Title: Mammal
Context: To maintain a high constant body temperature is energy expensive – mammals therefore need a nutritious and plentiful diet. While the earliest mammals were probably predators, different species have since adapted to meet their dietary requirements in a variety of ways. Some eat other animals – this is a carnivorous diet (and includes insectivorous diets). Other mammals, called herbivores, eat plants. A herbivorous diet includes subtypes such as fruit-eating and grass-eating. An omnivore eats both prey and plants. Carnivorous mammals have a simple digestive tract, because the proteins, lipids, and minerals found in meat require little in the way of specialized digestion. Plants, on the other hand, contain complex carbohydrates, such as cellulose. The digestive tract of an herbivore is therefore host to bacteria that ferment these substances, and make them available for digestion. The bacteria are either housed in the multichambered stomach or in a large cecum. The size of an animal is also a factor in determining diet type. Since small mammals have a high ratio of heat-losing surface area to heat-generating volume, they tend to have high energy requirements and a high metabolic rate. Mammals that weigh less than about 18 oz (500 g) are mostly insectivorous because they cannot tolerate the slow, complex digestive process of a herbivore. Larger animals, on the other hand, generate more heat and less of this heat is lost. They can therefore tolerate either a slower collection process (those that prey on larger vertebrates) or a slower digestive process (herbivores). Furthermore, mammals that weigh more than 18 oz (500 g) usually cannot collect enough insects during their waking hours to sustain themselves. The only large insectivorous mammals are those that feed on huge colonies of insects (ants or termites).

question: To be able to maintain a constant body temperature, what do mammals need to maintain? 

answer: nutritious and plentiful diet

question: What does a omnivore imply? 

answer: eats both prey and plants

question: What do the majority of mammals under 18 oz eat? 

answer: insects

question: What determines a mammals diet type? 

answer: The size
Title: Mammal
Context: The deliberate or accidental hybridising of two or more species of closely related animals through captive breeding is a human activity which has been in existence for millennia and has grown in recent times for economic purposes. The number of successful interspecific mammalian hybrids is relatively small, although it has come to be known that there is a significant number of naturally occurring hybrids between forms or regional varieties of a single species.[citation needed] These may form zones of gradation known as clines. Indeed, the distinction between some hitherto distinct species can become clouded once it can be shown that they may not only breed but produce fertile offspring. Some hybrid animals exhibit greater strength and resilience than either parent. This is known as hybrid vigor. The existence of the mule (donkey sire; horse dam) being used widely as a hardy draught animal throughout ancient and modern history is testament to this. Other well known examples are the lion/tiger hybrid, the liger, which is by far the largest big cat and sometimes used in circuses; and cattle hybrids such as between European and Indian domestic cattle or between domestic cattle and American bison, which are used in the meat industry and marketed as Beefalo. There is some speculation that the donkey itself may be the result of an ancient hybridisation between two wild ass species or sub-species. Hybrid animals are normally infertile partly because their parents usually have slightly different numbers of chromosomes, resulting in unpaired chromosomes in their cells, which prevents division of sex cells and the gonads from operating correctly, particularly in males. There are exceptions to this rule, especially if the speciation process was relatively recent or incomplete as is the case with many cattle and dog species. Normally behavior traits, natural hostility, natural ranges and breeding cycle differences maintain the separateness of closely related species and prevent natural hybridisation. However, the widespread disturbances to natural animal behaviours and range caused by human activity, cities, dumping grounds with food, agriculture, fencing, roads and so on do force animals together which would not normally breed. Clear examples exist between the various sub-species of grey wolf, coyote and domestic dog in North America. As many birds and mammals imprint on their mother and immediate family from infancy, a practice used by animal hybridizers is to foster a planned parent in a hybridization program with the same species as the one with which they are planned to mate.

answer: clines

question: What is the given name of a lion and tiger hybrid? 

answer: liger

question: What is the given name of a offspring from two different animals? 

answer: hybrid
Title: East_India_Company
Context: Soon after the defeat of the Spanish Armada in 1588, London merchants presented a petition to Queen Elizabeth I for permission to sail to the Indian Ocean. The permission was granted, and despite the defeat of the English Armada in 1589, on 10 April 1591 three ships sailed from Torbay around the Cape of Good Hope to the Arabian Sea on one of the earliest English overseas Indian expeditions.

Title: East_India_Company
Context: In the next two years, the company established its first factory in south India in the town of Machilipatnam on the Coromandel Coast of the Bay of Bengal. The high profits reported by the company after landing in India initially prompted King James I to grant subsidiary licences to other trading companies in England.

Title: East_India_Company
Context: The company, which benefited from the imperial patronage, soon expanded its commercial trading operations, eclipsing the Portuguese Estado da Índia, which had established bases in Goa, Chittagong, and Bombay, which Portugal later ceded to England as part of the dowry of Catherine de Braganza. The East India Company also launched a joint attack with the Dutch United East India Company on Portuguese and Spanish ships off the coast of China, which helped secure their ports in China. The company established trading posts in Surat (1619), Madras (1639), Bombay (1668), and Calcutta (1690). By 1647, the company had 23 factories, each under the command of a factor or master merchant and governor if so chosen, and 90 employees in India. The major factories became the walled forts of Fort William in Bengal, Fort St George in Madras, and Bombay Castle.
