5. The Evolutionary Future Is Near!...................... 6 Phylogenetic Tree Animals today are facing many environmental stresses like the decline of prey and the loss habitat. Animals deal with these stresses by adapting using the mechanisms of evolution: founder effect, bottleneck, nonrandom mating, mutation, and natural selection. The animal we’ll be focusing on is the Acinonyx Jubatus, also known as the cheetah. According to the phylogenetic tree, the cheetah came from a common, but distant ancestor …show more content…

With these evolutionary changes, the cheetah strives at being the fastest land mammal. The skin protects the cheetah from injuries and actually helps them with camouflage; the cheetah’s fur is covered in solid black spots just like their skin. The black fur actually grows out of the black spots on their skin giving the cheetah it’s spotted pattern. The cheetah have an enlarged heart, lungs, nostrils, and sinuses that allow the animal to deliver oxygen to its muscles more effectively. Along with the cheetah’s fur, the cheetah’s warm blood keeps the animal body temperture at a constant rate and keeps the animal warm on cold …show more content…

For instance, our friend the cheetah, evolved from a trout and a rabbit according to the phylogenetic tree we discussed earlier in “Phylogenetic Tree”. Due to the cheetah’s evolutionary changes, a new species is born; the Acinonyx Tabatus or the Celion. The Celion is somewhat similar but different from the cheetah due to some evolutionary changes. If we take a look at the phylogenetic tree below of the celion, we can see the evolutionary history of the cheetah and celion.
Above we can see the evolutionary history of the cheetah and the celion. It appears that the celion has some Ancestral Traits. Ancestral Traits are features that do appear in ancestors. These features are: skin, lungs, warm blood, fur, canine teeth, and a spotted pattern. However, unlike the cheetah, the celion has more physical features that will better suit it for survival. Due to the evolutionary changes that took place after the cheetah, the celion has a higher density of capillaries, retractable claws, and hair rather than fur. These traits are what you’ll call “derived traits”. Derived traits are newly evolved features that do not appear in ancestors. With these traits the celion is fit (best suited to survive). If the celion is fit, then it is fit enough to live and fit enough to

With over 8.7 million different types of species on earth, it is difficult to see how a singular unicellular organism evolved and adapted to form the human and the rest of these species. With a large amount of the human evolutionary record discovered, it is clear that humans are apart of the order primates and share their closest relatives in this group. Other primates include gorillas, monkeys, lemurs and around 300 more species. Due to the fact that this order is so large, there are many similarities between the different species. Although there are similarities between the species, like the Western Lowland gorilla and the Black-handed Spider monkey, the majority of the comparisons are differences.

Structure: Leg Function: To be able to move Evolutionary Change: Bottleneck Effect Explantation: Due to the bottleneck effect the forest fox will lose its genetic variation between leg size because the forest foxes with the shorter legs have a lower chance of survival because the ones with the longer legs will end up being more athletic. Also due to co-evolution with its predators like a tiger, the fox will grow legs to be able to outrun the tiger, but the tiger will also evolve to have longer legs to be able to catch the fox. This is macroevolution because all land mammals will need to have longer legs because the faster they

Imagine in the extremely hot and dry Arabian Desert in south East Asia two potentially very dangerous animals engage in combat. The two animals are the incredibly venomous King Cobra and the other animal is the very agile Indian Gray Mongoose. Which animal will be victorious? Scientists have studied the traits and adaptations of the animals for centuries. If a King Cobra and an Indian Grey Mongoose were to engage in combat then based on the information the Indian Grey Mongoose would be victorious.

This theory considers the movement of life from the ground into the trees as the most important catalyst in the evolution of the ancestral primate. The essential features of the primate evolved because they were necessary and therefore had greater fitness for creatures swinging from branches. The visual predation hypothesis does not seek to debunk the arboreal hypothesis, but takes note that other arboreal mammals have not evolved in the same way as primates. Cartmill pointed to animals like the squirrel which does not have features such as advanced care of young.

Throughout the years, primate evolution has been influenced by climate changes. This is because the bodies of these creatures have adapter over the years to the conditions surrounding their environment. Influences include the upright walking adaptation that was mainly an adaptation associated with dried habitats to not receive heat over their backs. The theories of early primate evolution include: the arboreal theory, the visual predation theory, and the angiosperm radiation theory.

[Accessed 06 February 2018]. Summary: This is a detailed timeline, mainly following the Equidae line originating from North America, however it does include information from other parts of the world and shows the evolution of the horse from the first predecessor, the Hyracotherium, also known as the Eohippus or Dawn horse. The factual article follows how the structure of the Equidae lineage has changed over the Epoch’s starting from 55.8 million years ago. There is images which give a detailed analysis of structural changes of

This behavioral adaptation combines well with the explained structural adaptation above, making the Jaguar able to kill its prey in different scenarios and environments - swamps, trees and many more. This behavioral adaptation that a Jaguar has powerful muscles allows it to do various activities such as swimming, climbing and jumping. Allowing the Jaguar to further more take its ability to kill its prey whenever it’s hunting in the wild.

This has impacted their survival in a larger manner than their environment has. For example: Sharks aren’t picky eaters. In the food chain, if a predator loses its prey due to extinction or endangerment, it’s likely that the predator will go extinct as well from lack of food. However, since sharks will eat nearly anything that moves, this has kept them from dying from starvation. These cartilaginous beasts’ meal is only variable by size.

That is also why each different animal gets its own branch on this family tree. Like whales, hippos are large and aquatic, the two groups evolved these features separately from each other. We know this because the ancient relatives of hippos called anthracotheres were not large or aquatic. Nor were the ancient relatives of whales that you see pictured on this tree – such as

What is convergent and divergent evolution? Whether the trait is a result of convergent or divergent evolution. Chimpanzee, gorilla, human all have in common prehensile hands unlike the other mammals. Describe what makes this trait an adaptation Primitive primates were quadrupeds just like the bear in the past but with time they started developing prehensilehands thatallow them to pick fruit, use stones for crushing nuts and kills insects and small animals for food. As some stop living in the trees their hands started developing fully into the hands human have today.

Another aspect of the cheetah’s survival is their respiratory system. Compared to other cats and humans, the cheetah’s nostrils are a lot bigger. These large nostrils and nasal passages allow the cheetah to breathe faster and let maximum air to enter the body and add fuel while the it sprints. The maximum amount of air enters the large lungs, which are able to energize the blood with a lot of oxygen. This rich oxygen is then pumped by the heart, as mentioned

Total of 32 photographs were obtained in 2008 and 2010. The data yielded captures of six adult cheetahs (5 males and 1 unidentified sex) and one sub-adult (unidentified sex). Of the 32 captured photo, 30 were captured after sunset and before sunrise (cite). The result showed that the behavior and ecology of the Saharan cheetah is severely constrained by the harsh desert environment. It also supported Farid Belbachir and his team predictions that Saharan cheetah are nocturnal, potentially wide-ranging, and occur at very low densities.

Learning a foreign language in elementary school is beneficial because it helps students build a better academic structure.   For example, a study in Louisiana showed showed that third and fifth graders who were taught a foreign language scored significantly higher on their Louisiana Basic skill test, than the students who did not take foreign language course (National Education Association).   This proves that incorporating a foreign language in an elementary school will help improve the school's test state test scores.
