A pig is any of the animals in the genus Sus, within the Suidae family of even-toed ungulates. Pigs include the domestic pig, its ancestor the wild boar, and several other wild relatives. Pigs are omnivores and are highly social and intelligent animals.[citation needed]
A typical pig has a large head with a long snout which is strengthened by a special prenasal bone and by a disk of cartilage at the tip. The snout is used to dig into the soil to find food and is a very acute sense organ. There are four hoofed toes on each foot, with the two larger central toes bearing most of the weight, but the outer two also being used in soft ground.
The dental formula of adult pigs is Failed to parse (Missing texvc executable; please see math/README to configure.): \tfrac{ 3.1.4.3}{ 3.1.4.3} , giving a total of 44 teeth. The rear teeth are adapted for crushing. In the male the canine teeth form tusks, which grow continuously and are sharpened by constantly being ground against each other.
With around 1 billion individuals alive at any time, the domesticated pig is one of the most numerous large mammals on the planet.
The domestic goat (Capra aegagrus hircus) is a subspecies of goat domesticated from the wild goat of southwest Asia and Eastern Europe. The goat is a member of the family Bovidae and is closely related to the sheep as both are in the goat-antelope subfamily Caprinae. There are over 300 distinct breeds of goat.
Goats are one of the oldest domesticated species, and have been used for their milk, meat, hair, and skins over much of the world. In the 20th century, they also gained in popularity as pets.
Female goats are referred to as "does" or "nannies", intact males as "bucks" or "billies", and their offspring are "kids". Castrated males are "wethers". Goat meat from younger animals is called "kid" or cabrito (Spanish), and from older animals is simply known as "goat" or sometimes called chevon (French), or in some areas "mutton" (which more often refers to adult sheep meat).
The Modern English word "goat" comes from the Old English gāt which meant "she-goat", and this in turn derived from Proto-Germanic *gaitaz (cf. Old Norse and Dutch geit "goat", German Geiß "she-goat", and Gothic gaits "goat"), ultimately from Proto-Indo-European *ghaidos meaning "young goat" (cf. Latin haedus "kid"), itself perhaps from a root meaning "jump" (assuming that Old Church Slavonic zajęcǐ "hare", Sanskrit jihīte "he moves" are related)[citation needed]. To refer to the male of the species, Old English used bucca (which survives as "buck") until a shift to he-goat (and she-goat) occurred in the late 12th century. "Nanny goat" (for females) originated in the 18th century and "billy goat" (for males) in the 19th.
Banana is the common name for herbaceous plants of the genus Musa and for the fruit they produce. It is one of the oldest cultivated plants. They are native to tropical South and Southeast Asia, and are likely to have been first domesticated in Papua New Guinea. Today, they are cultivated throughout the tropics. They are grown in at least 107 countries, primarily for their fruit, and to a lesser extent to make fiber, banana wine and as ornamental plants. Its fruits, rich in starch, grow in clusters hanging from the top of the plant. They come in a variety of sizes and colors when ripe, including yellow, purple, and red.
Almost all modern edible parthenocarpic bananas come from two wild species – Musa acuminata and Musa balbisiana. The scientific names of bananas are Musa acuminata, Musa balbisiana or hybrids Musa acuminata × balbisiana, depending on their genomic constitution. The old scientific names Musa sapientum and Musa paradisiaca are no longer used.
Banana is also used to describe Enset and Fe'i bananas, neither of which belong to the aforementioned species. Enset bananas belong to the genus Ensete while the taxonomy of Fe'i-type cultivars is uncertain.
