My evidence for evolutions is how hippos have adapted to dominate by gaining helpful traits and evolving new ones. You’re probably thinking that hippos are a very dangerous and hurtful animal, which is true, but they are very important in their ecosystem and have evolved from many various animals to be the wonderful yet dangerous beasts they are today.
The hippopotamus is a herbivorous mammal that inhabits in the rivers south of the Sahara Desert. Most hippopotamuses are highly ranked to be one of the most dangerous animals in the whole world. Hippopotamuses have also had a very huge feeding adaptation that impacted their lives.
They have adapted thick lips and wide snouts that are designed for their aggressive eating habits. Hippos usually are very inactive and their diet mostly consists of eating lots of grass. They eat small portions which don’t give them much energy throughout the day, A hippos stomach can hold up to to day's worth of food. If need be, hippos can go without food for about a good three weeks. Since hippos evolved from a lot of water mammals, they spend most of their time in

They are a type of mammal that lived in the ocean. They evolved from anthracotheres 15 million years ago. This ancestors was terrestrial. Another ancestor of the hippo, were the first whales to evolve on earth, Pakicetus. Pakicetus were a type of land mammals. Hippos are a mammal that has been around for some time now. Evidence suggests they walked on earth more than 55 million years ago. Fossils of ancient hippos in Africa date back to about 16 million years ago. They have been looked at very carefully and give us some sight about hippo evolution. Multiple theories about hippo evolution that their ancestors took to the water after the earth cleared most of the forests. They were too vulnerable on land and moved into the water. Lack of food in the water is why they continued to go on land so they could eat and
The full scientific classification of the giraffe is Animalia Chordata Mammalia Artiodactyla Ruminantia Pecora Giraffidea Giraffa camelopardalis. There were at one time seven species in the genus Giraffa but today only one is still extant: camelopardalis, (Mitchell and Skinner, 2010). Because the modern giraffe does not have any other extant species within its genus, it is helpful to look the phylogenetic tree from a broader perspective. Going beyond the level of genus, the giraffe belong to the family Giraffidea. This family, though, is very small, as it only contains two different extant genera: Giraffa and Okapia, (Lerner and Lerner, 2008) Okapia, or the okapi, represents the closest living relative to the giraffe, and the two are very similar both morphologically and molecularly. The two animals can trace their ancestry back from the “gelocid ancestral assemblage” 20-25 million years to the family Palaeomeridae. From the palaeomerycids arose the Antilocaprinae from the subfamily Dromomerycinae, and two subfamilies of giraffids, the Climacoceratidae and Canthumerycidae. (...
Understanding what science is is crucial because evolution is based on changes that people can see in an organism. With it being science (as it can be seen/tested), evolution is something that should be taught in schools. The evidence for it being able to be seen and tested is as follows: all of the major scientific fields show evidence supporting the theory (“NSTA.”) .... ... middle of paper ...
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
I visited the Oriental Institute of Chicago Museum, which contains various artifacts, I choose a Model Hippopotamus from Egypt. The hippopotamus is dated to Egypt’s Middle Kingdom, circa 1878 BC. According to wall text at the Oriental Institute of Chicago, hippopotamuses in Egyptian culture represented the enemies of the ruler. I was attracted to the Model Hippopotamus based on its size/shape, lines, texture, and the color.
Scientists had some idea to the evolutionary process of whales. “It has always been clear that aquatic cetaceans must have evolved from terrestrial mammals and returned to the water, and the forelimbs of recent cetaceans still have the same general pattern as that of land mammals.” (Walking with Whales) It was known fact that land mammals and whales were related. However, the change from ancient whales to modern whales is drastic.
However, they began to go extinct when North America merged lands with the Southern counterparts, allowing placentals to move into South America and largely outcompete them (Moskowitz ,2010). Placentals now occupy one of the widest range of environments from marine to terrestrial. In order to thrive in the environments they are subjected to, eutherians have evolved various structural adaptations. They vary in size from shrews to whales. Being housed largely in tropical Asia, shrews (Eulipotyphla) are terrestrially adapted to dig burrows to hide from predators and forage for food with their reduced body size. In contrast, whales (cetacea) are the largest creatures dominating deep oceans. With its enlarged body size, its stomach is able to contain one tonne of krill for feeding (WWF, 2016). Contrastingly, the marsupials like kangaroos and koalas, as well as monotremes including the duck billed platypus and spiny anteater, all remained and possesses similar body sizes, completely lacking diversity compared to the
The seahorse's scientific genus name, Hippocampus which is derived from the Greek hippokampus (hippos, meaning “horse,” and kampos, meaning “sea monster”)
I was coming back from school, Once I got home I went to the bathroom to have a bath. All of a sudden, There was a baby hippo in my bathroom!! I got so surprised that a random baby hippo was in my bathtub, that I slipped and fell. After, I got up I thought it was a dream but no the hippo was still in my bath. The first thing I did was try to get that stinking hippo out of my bathtub, I tried pushing it out, scaring it, I even tried to tickle it. But none of my strategies worked. In the end I just got tired from doing all those things. Who knew a baby hippo could weigh so much. Then I looked at the time and I noticed it was 5:45 my parents were coming in fifteen minutes!! I got so scared to see their
The origin of modern day whales, a mystery that has puzzled paleontologists for years, may have just been solved with the discovery of an ankle bone. This discovery might sound simple and unimportant, but the bones of these ancient animals hold many unanswered questions and provide solid proof of origin and behavior. The relationship between whales and other animals has proven to be difficult because whales are warm-blooded, like humans, yet they live in the sea. The fact that they are warm-blooded suggests that they are related to some type of land animal. However, the questions of exactly which animal, and how whales evolved from land to water, have remained unanswered until now.
There is much evidence of population evolution. Some evidence they found of population evolution are fossils. Fossils are historical records. Over millions of years ago land eroded and was carried away by rivers and ended up in the bottoms of oceans compressing older deposits into the rock. Dead organisms settled along the
The Triceratops (figure 1) was and herbivore that lived in the late Cretaceous period, which was around 125 million years ago. The Triceratops existed at least 66 million years ago. It was a Rhinoceros-like dinosaur that had a sturdy body structure. It had four legs, three horns, and big eyes. Triceratopses were very complex.
The gorillas live mainly in coastal West Africa in the Congo, Zaire, Gabon, Equatorial Guinea and Cameroon. Gorillas live in the rain forest. They usually live on the ground but build nest in trees to sleep in. Gorilla troops keep a 15-20 square mile range which often overlaps the range of other troops. There are three different kinds of gorillas. The eastern lowland gorilla the western lowland and the mountain gorilla. They are herbivores and eat only wild celery, roots, tree bark pulp, fruit, stems of many plants and bamboo shoots. They spend nearly half their day eating.
Despite this fact many people argue that evolution has no facts to support it and there are several reasons why evolution can't happen. Evolution is the gradual change in an organisms gene pool over time, basically evolution is described in any change in the genetic makeup of an organism. The easiest way to show this is by stating examples of low level evolution as it has been observed. The best know case of this kind happened in England during the industrial evolution. There were two varieties of the English Peppered moth before the revolution, a light and a dark colored moth.
When Indo-Pacific Humpback Dolphins are first born, they are dark gray and get lighter as they grow older, sometimes this will cause spots (WCD). According to Whitfield on page 114, when the Indo-Pacific Humpback dolphin is young it has a normal streamlined body figure, but when it grows older it start to form fatty tissue humps. They have the average lifespan of 40 years (WCD). The Indo-Pacific dolphin can be between 6 ½ feet to 10 feet long with 120 teeth in their long beak. Using their long beak to eat, these dolphins swim up to the shallow waters and hunt for fish (Whitfield 114). Indo-Pacific dolphins are not the only type of dolphins that pray on the
Without evolution, and the constant ever changing environment, the complexity of living organisms would not be as it is. Evolution is defined as a process that results in heritable changes in a population spread over many generations (8).Scientists believe in the theory of evolution. This belief is based on scientific evidence that corroborates the theory of evolution. In Figure 1 the pictures of the skulls depict the sequence of the evolution of Homo-sapiens. As the figure shows, man has evolved from our common ancestor that is shared by homo-sapiens. The change of diet of homo-sapiens over time has thought to contribute to the change in jaw structure and overall skull shape.
