Evolution Of Foot Structure
Like any of the living creatures, the horse structure has been developed over a period of 40 million years. We will discuss the evolution of the horse body and foot structure, in 4 stages of its evolution from the Eohippus to the modern horse in the below essay.

40 million years ago, the horse was called Eohippus. Its body was small, bold; without the hair on its neck, with a small face and it had a small thin foot of 4 small limbs. 10 million years later, the horse was evolved to Mesohippus, its body became bigger with taller legs, taller tail, hair started to appear on its neck and its hoofs was decreased to 3. Later by another 15 million years, the Merychippus has a stronger body, with taller hair than the previous Mesohippus. Also, it

    The “pattern” to the skeleton of the human arm that was discovered by Sir Richard Owen was: one bone, two bones, lotsa blobs, and digit pattern. This pattern relates to his idea of exceptional similarities because it shows the basic structure of arms or legs of mammals. 2. How did Charles Darwin’s theory explain these similarities that were observed by Owen?…

    During the Pleistocene epoch, or 1.8 million years to 10,000 years ago, Homo floresiensis occupied the Liang Bua, a cave on Flores in eastern Indonesia. They were relatively small people, identical to modern-day dwarfs. But after researching recovered fossils of their bodies scientists realize there are distinct differences; one of these differences happens to be the foot of h. floresiensis.…

    As the horse got larger, larger limbs were required to support its increasing size. From Hyracotherium to Equus, the central metatarsal length and width almost quadrupled, and the number of toes reduced from three toes to one hoof. These new characteristics allowed the horse to avoid predators in the new grassland environment better. Longer limbs allowed the horse to run faster and for longer periods of time, and with less toes, there was less muscle weight to drag their speed. These adaptations contained trade-offs, since it reduced the ability of the horse’s dexterity and agility, but since their environment no longer contained many forests and trees, they didn’t necessarily need these characteristics. A change in environment didn’t only change the diet and teeth of the horse, but it also changed the horse’s body to adapt to the ways it could move.…

    based on analyzing a cladogram it shows the relationships among representative organisms such as lamprey, tuna, bullfrog, snapping turtle, kangaroo, rhesus monkey, and human. As we analyze, the most primitive were the lamprey since it is the root or the ancestors of the other organisms as the cladogram shows and the most advanced are the humans because they are more modified.…

    Many processes have taken place to shape humans from the Australopithecus Afarensis to the modern day human also known as the Homo Sapien. As a result, the two defining traits that occurred by taxonomy are the effects of brain size and bipedalism. Humans, like other primates are considered as Order Primates in the Hominidae family and therefore are a prime example of taxonomy when the two diverged into different species. During taxonomy when humans diverged from their ancestors 6 to 7 million years ago, the result is the differences such as walking upright, brain size and overall skeletal structure are prominent due to the divergence of humans and other primates. Although primates and humans both share many anatomical, behavioral and socialization traits the differences are drastic and are all a result of selective pressures.…

    Along with a big brain, opposable thumbs, bipedalism is one of the characteristics that makes the human species unique. The dictionary defines bipedalism as “a condition of using two feet for standing or walking”. Walking on two legs allowed our ancestors to see better, have freed up hands, and eventually become erect. Bipedalism is one of the initial driving force of the human evolution.…

    Evolutionary theory explains the existence of homologous structures adapted to different purposes as the result of descent with modification from a common ancestor. Similarities and differences among homologous structures help determine how recently species shared a common ancestor. For example the front limbs of reptiles and birds are more similar to each other than either is to the front limb of an mammal. This similarity indicates…

    For this assignment we are looking at the skeletal system. The skeleton is the internal framework of our body. It is made up of three things; bones, cartilage and joints. Without these three things we would just be a heap of skin, muscle and internal organs. The skeleton is made up of 206 bones that are separated into two groups. Firstly, the Axial Skeleton. The Axial skeleton is made up of 80 different bones whereas the Appendicular skeleton is made up of 126 bones.…
