The horse that we know today developed from a small creature about the size of a small-dog, the fossil record of horses extend back to 50 million years ago. During evolution, some horses had survive tough conditions to breed the next generation this process known as natural selection. The horse developed into completely different animal from Hyracotherium also known as “Eohippus” meaning the “Darwin horse” to Equus, today's horses. Throughout the millions of years many changes had occurred to the evo-lution of horse, this essay will discuss the evolution of horses with the use of tayony, natural selection and modern research.
When naming, describing, and classifying organisms including all animals, plants and microorganisms of the world, taxonomy is the right name used for this in science. The term taxonomy is used for the classifi-cation of living and once-living organisms. Taxonomy also refers to "scientific classification" or "biological

The fossil record of horses extends back to an odd-toed ungulate mammal belonging to the taxonomic family Equidae, a dog-like ancestor 55 to 42 million years ago in the genus Hyracotherium in North America. Hyracotherium had a primitively little face , four-toed forefeet, three-toed hind feet, an arched back, small brain, and higher hindquarters than forehand. Later genus has increased in body size, brain complexity, the size of cheek teeth, lengthening of the face, and reduction of toe number. However, even though horses got larger over time but these trends are not seen in all of the horse lines. Genus such as Hipparion existed from 23 to 2 million years ago, showed gains in size, But some later genus such as Archeohippus, and Calippus got smaller again (Boundless, 2016),(Encyclopedia of Life,2015), (equineworld.co.uk, 2014), (Molen, M.
Not only are giraffes the tallest animals in the world, they are also one of the most recognizable. Their characteristic long necks quickly captivate any audience. That being said, it is not commonly known that there are thought to be nine subspecies of Giraffa camelopardalis. In fact, there is increasing evidence that these could potentially be separate species in their own right. This paper will discuss where giraffes fit in the Tree of Life and identify the giraffe’s closest relatives, differentiate and analyze the similarities and differences between the nine subspecies, and, finally, explore any debate revolving around the phylogeny of the subspecies.
Indian Horse is a novel by Richard Wagamese that beautifully explores the idea of family, and what it means to have people around you that make you feel at home. The reader is bombarded with an overwhelming sense of family and betrayal in the first few pages of the novel. As Richard Wagamese continues to write, one is able to see how safe Saul Indian Horse felt with his biological family, and he also shows how lost he felt without their love when he was taken to the Residential School. The school he was brought to was drained of all consensual love the moment it was open, and continued to fill the children with horrible feelings the entire time they were there. Indian Horse was unable to really feel as though he still had family while he was in the
I can remember being a little kid and listening to stories my Grandpa and Great Grandpa told about the mustangs that used to be around the Black Canyon. They used to tell stories about when they would put their mares out with the mustangs during the winter to get bred. Then they would go out in the spring and catch their mares. They told stories of the times they had to chase the mustangs from the fields during the winter so the cattle could eat. They told of when they would go and capture the colts from the herd to keep for themselves. I can even remember the last one they ever had. He was at least 25 years old when I saw him. The last I knew of the mustangs Bureau of Land Management (BLM) rounded the herd up and that is all I ever heard.
Seahorses are a prime example of species whose atypical biology and unusual global distribution leads to a series of evolutionary questions. Seahorses (genus Hippocampus) are a marine species that have extensively been studied because of their abnormal behaviors in the marine environment compared to other marine creatures. Many of the seahorse species have large ranges, both longitudinally (over a great horizontal distance across the ocean), and latitudinal (great vertical distance within the ocean), regardless of the fact that they are characterized as weak swimmers and lack any large structural fins for efficient swimming (Lourie et al., 1999a). Although they do have these large range environments, seahorses

Laurel discovers the significant meaning of the memories and past to her, yet she could not survive in staying fully attached to it.
Grand champion! I was riding Fancy, a paint horse, at the Dallas County Fair in the Horsemanship class. In this class, I had to complete a pattern and it was judged on how well each horse and rider completed the pattern. The judge felt that Fancy and I performed best and awarded me with a big purple ribbon and a trophy with a horse on top. At the end of the fair, all of the grand champions were announced before the races. That was the final reward for successfully showing a horse in competitions.
For decades, Scientists have contemplated the idea of using horses for the personal gain of children and adults with needs such as autism, heart conditions, anxiety, stress, and other disorders that have yet to be curable. Horses such as Chester, a twenty year old gelding has encouraged more young riders who face difficulties such as social skills, behavior skills, and those who are physically indisposed. The phrase confidence is key, becomes important when people of all ages interact with a horse. Learning confidence may not be as easy as it sounds but is a necessary step to bond with a horse; without it, there can be no trust and most importantly, no bond between the equine and its rider.
Equine veterinarians are animal doctors who provide medical care for horses. They examine, test and occasionally operate on or euthanize the animals. Travel to ranches and farms is often necessary, and equine vets have to work outdoors in various types of weather conditions. Being an equine veterinarian is a pleasant career choice because of great interactions with varied types of horses and their owners , the basic information, and the pros and cons of an equine veterinarian.

he horse, Equus ferus caballus, is a subspecies from the family Equidae. Over the past 50 million years, through survival adaptations, the common horse has evolved from a relatively small, multi-toed animal into the large, single toed animal known today (Wilson,. Mammal Species of the World (3rd ed.). Baltimore).
Analysis of a poem - Horses by Edwin Muir It is said that one should Forget the past and live in the present It is said that one should forget the past and live in the present. However, Edwin Muir’s ‘Horses’ is a poem of past memories. The The interesting part is that it deals with many conflicts and issues which are prevalent even today. It is thus a bridge between the past and present and expressed in the form of a piece of literature. Muir himself said that in writing about horses in this poem, he was reflecting his childhood view of his father’s plough horses, which must have seemed huge, powerful and mysterious to a boy of four.
Horses are a majestic creature that have been used since the dawn of time developing from wild animals, to farm workers, to warriors on the battlefield, to carriage pullers, show horses, and pets. Horses have had many opportunities and the ability to work alongside people playing a vital role in many different tasks they have been assigned to. Horses are willing, courageous, and hardy workers as they allow humans to ride and work with them. Though, have you ever seen a horse do something unnatural and have you ever thought that a human may tweak a horse’s natural ability to obtain a new skill that catches the human eye? Well I have been riding and showing horses for many years now
Horse racing is a fickle sport. One minute, a horse and its connections are on top of the horse racing world and one misstep later, it all comes crashing down.
Species are grouped into genera. A genus is a group of species thought to have a fairly recent common ancestor. Genera are grouped into families. Some of are very natural, while others are more mixed. Families are grouped into orders. Orders are grouped into classes. Classes are grouped into divisions or phyla. The highest level of classifications is that of the kingdom.3 There are many objectives of plant taxonomy in which the collection of plants, their studies in the herbarium (scientific names, identification and characteristics of plants) is the first objective of plant taxonomy, and the second objective is to give a method of diagnosis of plants, by the help of available fundamental data and pictorial matter etc and the last objective of plant taxonomy is to preparation of phylogenetic system of
Horseback riding is not an activity most people think of, but it is a great escape for some people. Horseback riding is not just saddling up and riding, people have to have a passion for horses and riding. Some things to keep in mind when riding is balance and knowledge on how to keep the horse under control. People can be told how to ride, but each person will have to find a style that works for them. When riding a horse the concept of time, destination and worries do not exist.
