The dog (Canis familiaris or Canis lupus familiaris) is a
domesticated descendant of the
wolf. Also called the domestic dog, it is
derived from
extinct gray wolves, and the gray wolf is the dog's closest living relative. The dog was the first
species to be domesticated by
humans. Experts estimate that
hunter-gatherers domesticated dogs more than 15,000 years ago, which was before the
development of agriculture. Due to their long association with humans, dogs have expanded to a large number of domestic individuals and gained the ability to thrive on a
starch-rich diet that would be inadequate for other
canids.
the domestic cat was the second most popular pet in the
United States, with 95.6 million cats owned and around 42 million households owning at least one cat. In the
United Kingdom, 26% of adults have a cat, with an estimated population of 10.9 million pet cats there were an estimated 220 million owned and 480 million stray cats in the world. (Full article...)

Birds are a group of
warm-bloodedvertebrates constituting the
classAves (/ˈeɪviːz/), characterised by
feathers, toothless beaked jaws, the
laying of
hard-shelled eggs, a high
metabolic rate, a four-chambered
heart, and a strong yet lightweight
skeleton. Birds live worldwide and range in size from the 5.5 cm (2.2 in)
bee hummingbird to the 2.8 m (9 ft 2 in)
common ostrich. There are over 11,000 living species, more than half of which are
passerine, or "perching" birds. Birds have
wings whose development varies according to species; the only known groups without wings are the extinct
moa and
elephant birds. Wings, which are modified
forelimbs, gave birds the ability to fly, although further evolution has led to the
loss of flight in some birds, including
ratites,
penguins, and diverse
endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly
seabirds and some
waterbirds, have further evolved for swimming. The study of birds is called
ornithology.
Many
social species pass on knowledge across generations, which is considered
a form of culture. Birds are social, communicating with visual signals, calls, and
songs, and participating in such behaviours as
cooperative breeding and hunting,
flocking, and
mobbing of predators. The vast majority of bird species are socially (but not necessarily sexually)
monogamous, usually for one breeding season at a time, sometimes for years, and rarely for life. Other species have breeding systems that are
polygynous (one male with many females) or, rarely,
polyandrous (one female with many males). Birds produce offspring by laying eggs which are fertilised through
sexual reproduction. They are usually laid in a nest and
incubated by the parents. Most birds have an extended period of parental care after hatching.
Many species of birds are economically important as food for human consumption and raw material in manufacturing, with
domesticated and
undomesticated birds being important sources of eggs, meat, and feathers.
Songbirds, parrots, and other species are popular as pets.
Guano (bird excrement) is harvested for use as a fertiliser. Birds figure throughout human culture. About 120 to 130 species have become
extinct due to human activity since the 17th century, and hundreds more before then. Human activity threatens about 1,200 bird species with extinction, though efforts are underway to protect them. Recreational
birdwatching is an important part of the
ecotourism industry. (Full article...)

The horse (Equus ferus caballus) is a
domesticated,
one-toed,
hoofed mammal. It belongs to the taxonomic family
Equidae and is one of two
extantsubspecies of
Equus ferus. The horse has
evolved over the past 45 to 55 million years from a small multi-toed creature, close to Eohippus, into the large, single-toed animal of today. Humans began domesticating horses around 4000
BCE, and their
domestication is believed to have been widespread by 3000 BCE. Horses in the subspecies caballus are domesticated, although some domesticated populations live in the wild as
feral horses. These feral populations are not true
wild horses, which are horses that never have been domesticated and historically linked to the megafauna category of species. 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
adapted to run, allowing them to quickly escape predators, and possess an good
sense of balance and a strong
fight-or-flight response. Related to this need to flee from predators in the wild is an unusual trait: horses are able to sleep both standing up and lying down, with younger horses tending to sleep significantly more than adults. 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 domesticated horses begin training under a
saddle or in a
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 more than 300 breeds of horse in the world today, developed for many different uses.
Horses and humans interact in a wide variety of sport competitions and non-competitive recreational pursuits as well as in working activities such as
police work,
agriculture, entertainment, and
therapy. Horses were historically used in warfare, from which a wide variety of
riding and
driving techniques 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. (Full article...)

The dog (Canis familiaris or Canis lupus familiaris) is a
domesticated descendant of the
wolf. Also called the domestic dog, it is
derived from
extinct gray wolves, and the gray wolf is the dog's closest living relative. The dog was the first
species to be domesticated by
humans. Experts estimate that
hunter-gatherers domesticated dogs more than 15,000 years ago, which was before the
development of agriculture. Due to their long association with humans, dogs have expanded to a large number of domestic individuals and gained the ability to thrive on a
starch-rich diet that would be inadequate for other
canids.
the domestic cat was the second most popular pet in the
United States, with 95.6 million cats owned and around 42 million households owning at least one cat. In the
United Kingdom, 26% of adults have a cat, with an estimated population of 10.9 million pet cats there were an estimated 220 million owned and 480 million stray cats in the world. (Full article...)

Birds are a group of
warm-bloodedvertebrates constituting the
classAves (/ˈeɪviːz/), characterised by
feathers, toothless beaked jaws, the
laying of
hard-shelled eggs, a high
metabolic rate, a four-chambered
heart, and a strong yet lightweight
skeleton. Birds live worldwide and range in size from the 5.5 cm (2.2 in)
bee hummingbird to the 2.8 m (9 ft 2 in)
common ostrich. There are over 11,000 living species, more than half of which are
passerine, or "perching" birds. Birds have
wings whose development varies according to species; the only known groups without wings are the extinct
moa and
elephant birds. Wings, which are modified
forelimbs, gave birds the ability to fly, although further evolution has led to the
loss of flight in some birds, including
ratites,
penguins, and diverse
endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly
seabirds and some
waterbirds, have further evolved for swimming. The study of birds is called
ornithology.
Many
social species pass on knowledge across generations, which is considered
a form of culture. Birds are social, communicating with visual signals, calls, and
songs, and participating in such behaviours as
cooperative breeding and hunting,
flocking, and
mobbing of predators. The vast majority of bird species are socially (but not necessarily sexually)
monogamous, usually for one breeding season at a time, sometimes for years, and rarely for life. Other species have breeding systems that are
polygynous (one male with many females) or, rarely,
polyandrous (one female with many males). Birds produce offspring by laying eggs which are fertilised through
sexual reproduction. They are usually laid in a nest and
incubated by the parents. Most birds have an extended period of parental care after hatching.
Many species of birds are economically important as food for human consumption and raw material in manufacturing, with
domesticated and
undomesticated birds being important sources of eggs, meat, and feathers.
Songbirds, parrots, and other species are popular as pets.
Guano (bird excrement) is harvested for use as a fertiliser. Birds figure throughout human culture. About 120 to 130 species have become
extinct due to human activity since the 17th century, and hundreds more before then. Human activity threatens about 1,200 bird species with extinction, though efforts are underway to protect them. Recreational
birdwatching is an important part of the
ecotourism industry. (Full article...)

The horse (Equus ferus caballus) is a
domesticated,
one-toed,
hoofed mammal. It belongs to the taxonomic family
Equidae and is one of two
extantsubspecies of
Equus ferus. The horse has
evolved over the past 45 to 55 million years from a small multi-toed creature, close to Eohippus, into the large, single-toed animal of today. Humans began domesticating horses around 4000
BCE, and their
domestication is believed to have been widespread by 3000 BCE. Horses in the subspecies caballus are domesticated, although some domesticated populations live in the wild as
feral horses. These feral populations are not true
wild horses, which are horses that never have been domesticated and historically linked to the megafauna category of species. 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
adapted to run, allowing them to quickly escape predators, and possess an good
sense of balance and a strong
fight-or-flight response. Related to this need to flee from predators in the wild is an unusual trait: horses are able to sleep both standing up and lying down, with younger horses tending to sleep significantly more than adults. 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 domesticated horses begin training under a
saddle or in a
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 more than 300 breeds of horse in the world today, developed for many different uses.
Horses and humans interact in a wide variety of sport competitions and non-competitive recreational pursuits as well as in working activities such as
police work,
agriculture, entertainment, and
therapy. Horses were historically used in warfare, from which a wide variety of
riding and
driving techniques 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. (Full article...)
