关于大象仿生学的作文

相传在公元前三千多年，我们的祖先有巢氏就通过模仿鸟类在树上筑巢来防

御猛兽的侵袭。四千多年前，我们的祖先“见飞蓬转而知为车，‘发明了有两个轮子的车，古代庙外面有柱子，非常粗，就好像大象的腿。

在春秋战国时代，鲁国的木匠鲁班开始研制能飞木鸟，西汉时期，有人用鸟的羽毛做翅膀，从山上飞下来，试着模仿鸟飞行动作。人类向鸟儿们学习怎样飞上蓝天。

人类从小鸟身上得到启示，发明了飞机，从长颈鹿身上得到启示，发明了抗荷飞行服。从金鱼身上得到启示，发明了潜水艇。

动物真是人类的好老师。

大象-elephant

Elephants are large land mammals of the order Proboscidea and the family Elephantidae. There are three living species: the African Bush Elephant, the African Forest Elephant and the Asian Elephant (also known as the Indian Elephant). Other species have become extinct since the last ice age, the Mammoths being the best-known of these. They were once classified along with other thick skinned animals in a now invalid order, Pachydermata.

Elephants are the largest land animals.[1] The elephant's gestation period is 22 months, the longest of any land animal. At birth it is common for an elephant calf to weigh 120 kilograms (260 lb). They typically live for 50 to 70 years, but the oldest recorded elephant lived for 82 years.[2] The largest elephant ever recorded was shot in Angola in 1956. This male weighed about 12,000 kilograms (26,000 lb),[3] with a shoulder height of 4.2 metres (14 ft), a metre (yard) taller than the average male African elephant.[4] The smallest elephants, about the size of a calf or a large pig, were a prehistoric species that lived on the island of Crete during the Pleistocene epoch.[5]

The elephant has appeared in cultures across the world. They are a symbol of wisdom in Asian cultures and are famed for their memory and intelligence, where they are thought to be on par with cetaceans[6] and hominids.[7] Aristotle once said the elephant was "the beast which passeth all others in wit and mind"[8]. The word "elephant" has its origins in the Greek ?λ?φα?, meaning "ivory" or "elephant".[9]

Healthy adult elephants have no natural predators[10], although lions may take calves or weak individuals.[11][12] They are, however, increasingly threatened by human intrusion and poaching. Once numbering in the millions, the African elephant population has dwindled to between 470,000 and 690,000 individuals.[13] The elephant is now a protected species worldwide, with restrictions in place on capture, domestic use, and trade in products such as ivory.

马- Horse

The horse (Equus caballus) is a hoofed (ungulate) mammal, one of eight living species of the family Equidae. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature into the large, single-toed animal of today. Humans began to domesticate horses around 4500 BC, and their domestication is believed to have been widespread by 3000 BC; by 2000 BC the use of domesticated horses had spread throughout the Eurasian continent. Although most horses today are domesticated, there are still endangered populations of the Przewalski's Horse, the only remaining true wild horse, as well as more common feral horses which live in the wild but are descended from domesticated ancestors.

There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size, colors, markings, breeds, locomotion, and behavior. Horses are anatomically designed to use speed to escape predators, and have a well-developed sense of balance and a strong fight-or-flight instinct. Related to this need to flee from predators in the wild is an unusual trait: horses are able to sleep both standing up and laying down. Female horses, called mares, carry their young for approximately 11 months, and a young horse, called a foal, can stand and run shortly following birth. Most horses begin training under saddle or in harness between the ages of two and four. They reach full adult development by age five, and have an average lifespan of between 25 and 30 years.

Horse breeds are loosely divided into three categories based on general temperament: spirited "hot bloods" with speed and endurance; "cold bloods," such as draft horses and some ponies, suitable for slow, heavy work; and "warmbloods," developed from crosses between hot bloods and cold bloods, often focusing on creating breeds for specific riding purposes, particularly in Europe. There are over 300 breeds of horses in the world today, developed for many different uses.

Horses and humans interact in many ways, not only in a wide variety of sport competitions and non-competitive recreational pursuits, but also in working activities including police work, agriculture, entertainment, assisted learning and therapy. Horses were historically used in warfare. A wide variety of riding and driving techniques have been developed, using many different styles of equipment and methods of control. Many products are derived from horses, including meat, milk, hide, hair, bone, and pharmaceuticals extracted from the urine of pregnant mares. Humans provide domesticated horses with food, water and shelter, as well as attention from specialists such as veterinarians and farriers.

骆驼 camel

Camels are even-toed ungulates within the genus Camelus. The dromedary, one-humped or Arabian camel has a single hump, and the Bactrian camel has two humps. They are native to the dry desert areas of western Asia, and central and east Asia, respectively.

The term camel is also used more broadly to describe any of the six camellike creatures in the family Camelidae: the two true camels, and the four South American camelids, the llama, alpaca, guanaco, and vicu?a.

The average life expectancy of a camel is forty to fifty years. A fully grown adult camel stands 1.85 m (6 ft 1 in) at the shoulder and 2.15 m (7 ft 1 in) at the hump. The hump rises about thirty inches (75 cm) out of its body. Camels can run up to 65 km/h (40 mph) in short bursts and sustain speeds of up to 40 km/h (25 mph).

Fossil evidence indicates that the ancestors of modern camels evolved in North America during the Palaeogene period, and later spread to Asia. Humans first domesticated camels before 2000 BC.[1][2] The dromedary and the Bactrian camel are both still used for milk, meat, and as beasts of burden—the dromedary in western Asia, and the Bactrian camel further to the north and east in central Asia.
