Evolution of the horse

you were to think of a horse today, you would say they are big, strong mammals. 55 mya, horses did not look like this. With the mannerisms of a deer and the traits of a dog, the first known horse darted through forests in North America during the Eocene Period. As time went by, many horses evolved like the Orohippus, Epihippus, Mesohippus, Miohippus, Parahippus, Merychippus, Pliohippus, Dinohippus, and finally the Equus. In Greek, ‘hippus’ means horse. Fossils of the first known horse were found in 1841, and were initially called Hyracotherium leporinum. In 1876, a full skeleton of it was found in North America by Othniel Marsh. It was then given the name Eohippus, which means “dawn horse”. Many believe it was the ancestor of modern…

Animal Project: Horse Horses have always been beside me all throughout my life. With my Aunt herself owning a barn, I had the perfect chance to become addicted to the equine world. And I took it! Ever since my first ride, I was hooked, and ended up becoming a competitive horseback rider. So naturally, I have collected a lot of information about them. That’s just why I’ve decided to share that information, and choose them to be constructed and written about for my animal project! The horse, or…

After dinosaurs went extinct about 65 million years ago, mammals began to evolve and diversify into new niches. In order to understand and disentangle this convoluted history of mammals, paleontologists narrowed the focus of their studies to horse because horse evolution occurred approximately at around 55 million years ago, and their fossil record is highly rich in details. In the next several paragraphs, we will discuss the morphological changes in horse from the Eocene epoch to the Holocene…

Theory Alicia Horsfield Evolution can be defined as a gradual process in which a species changes into a different and more complex form. This happens over several generations. Evolution also proves that all species are related through genetic variation. (yourgenome.org, n.e). Charles Darwin (1809-1882) was an English Naturalist, famous for creating the theory of ‘evolution’. He also created a theory that species survive through a process called “natural selection”. The species that…

changes that occurred in the Equidae family that are as significant to evolution as body size. The discovery of Equidae fossils worldwide has provided excellent evidence of the evolution which has affected many characteristics of the family. An example of one or the most notable alternations seen between the first ancestor, the Eohippus of the Eocene period, and modern Equus can been seen in the feet and limbs of each and through the many related species also in the family tree. As…

Evolution is the change in allele frequency in a population over time or, more simply, the process by which populations of organisms change over time (helped by the process of natural selection). Artificial selection does support this theory, except that the evolution happens intentionally, instead of naturally. Due to random mutations, variation within a population exists, allowing certain characteristics/genes to be selected as more favorable than others. Therefore, humans breed organisms with…

The subject of evolution is widely debated topic. However there is a wide variety of evidence that supports evolution. By studying the fossil record, comparative anatomy, genetics and natural selection scientists have been able to support Charles Darwin’s theory (evolution). This report will focus on evidence from the fossil record as well as genetics. The fossil record is the collection of information that shows the occurrence and evolution of living organisms through geological time from…

Horses started with evolution of dinosaurs. First were wild animals Slowly began to help the early indians. They was worked and pushed them into work force and tame the wild horses. With the amazing nine times larger then human eyes are usually 5 centimeters around. They can sleep standing up due to the support of their forelegs and hind legs. Their small stomach only has a capacity of 2 to 4 gallons for an average-sized 1000 lb. horse. So this will limit how much they can eat or take in at a…

The Peruvian Paso Horse - A Smooth Ride for Everyone by Julie Dees Aside from their flashy good looks, the gait of the Peruvian Paso horses is what makes this breed so popular. They are known worldwide for their smooth, rocking horse style ride. The easy gait and manageable size makes riding accessible for those with disabilities. Riders with age-related or back problems often choose the Peruvian Paso over most breeds. Oklahoma State University's Ag Department considers this the smoothest…

A horse is a horse, of course, of course, from the introduction to the 1960s show Mr. Ed. Sounds pretty simple, as long as you know what a horse is. Now everyone typically knows what a horse looks like, but what truly makes a horse a horse? More specifically what makes something not a horse? First let 's answer the question what makes a horse a horse in scientific terms. “The horse family today is quite small, consisting only of seven living species, which include donkeys and zebras. The closest…
