Similarities Between African Elephants And Columbian Mammoths

Not surprisingly, elephants are known for being more emotional and empathetic animals than the rest. According the three articles, “Elephants Can Lend a Helping Trunk”, “Elephants Know When They Need a Helping Trunk in a Cooperative Task”, and “Elephants Console Each Other” elephants understand when they need each other’s assistance. All two authors describe the studies of elephant behavior differently, but with a similar purpose.

Explanation and Analysis: There really are a lot of characteristics overlooked when talking about Elephants as a whole species.

From its early stages as a 40 cm tall, 25 kg Eohippus to its current state as a 1.6 meter tall, 500 kg beast, every step can be traced through an abundance of fossils located mostly right here in the United States. While the changes in equids from their beginnings until now are drastic, I found it interesting that it was not necessarily gradual. Most of the changes in size, structure and teeth did not happen until the Miocene, upon which the development was rapid. Figure 5 shows the mass of Equid genera in comparison to when they lived. For the first half of equid development, barely any change occurred. This displays how important environmental factors are in the evolution of species; without the emergence and prominence of open grasslands in the Miocene, horses as we know them today would almost certainly not

Hey! No large domestic animals, so there's your excuse for a failure in the Americas. But there was a domestic mammal throughout the two continents:

A. Rus hoelze et al, studied the impact of intense hunting of Northern Elephant Seals in the late 19th century, whose genetic variation reduced due to this bottleneck. This reduced their population size to just about 20. They found that although it has since rebounded to over 30K now but compared to their southern counterparts i.e., Southern Elephant Seals they have much less genetic variation. The Southern Elephant Seals didn’t went through this bottleneck event. It is clear that the genes of Northern Elephant Seals still carrying the marks of this bottleneck.

It is estimated that mammoths had the largest biome on the plant at an estimated 1 square kilometer per mammoth (Zimov, 2014). Herbivores of the time ranged from under 45 kilograms to well over 1000 kg, making for a wide range of diversity within the speciation (graph below). While many of these mammals were preyed upon by the carnivores, some were simply too large to be killed by single predators, causing them to be relatively immune to predation (Rodriguez, Alberdi, Azanza, Prado, 2006).

1. How did Australopithecus differ from other mammals? Australopithecus is differ from other mammals by Australopithecus lived from 4 million to 1 million B.C. ago, found in southern and Eastern Africa, have brain size of 500 cubic centimeters, and they are the first creature to know how to walk upright. 2.

For about twenty eight years now the Asian elephant has been struggling for existence. They have been classified as endangered species by The International Union for Conservation of Nature (IUCN). Twenty eight years is quite a large amount of time for an animal to be classified as endangered so The Zoological Society of London decided to look into this issue. Asian elephants have been transferred to captivity for quite some time in the North American region. The Elephas maximus have been captured from these countries in southern Asia and brought over to North America and have experienced many complications that can hinder the genetic diversity of the evolution of the species. Captive populations of the Elephas maximus species may be essential for genetic preservation and aid in decreasing the deterioration of the authentic population (Brenneman et al. 2011).

The DNA is very similar between the Mammoth and Mastodon. Which is why the evidence shows that they came from a common ancestor. The evidence shows that the Mammoth and Mastodon were around the same time and they were very similar to each other. They share me features and characteristics. I looked at some evidence that showed they were around the same time because there were fossil records found around the same time period and in the same sediment layers. I also found some evidence explaining that the Mammoth and Mastodon are very similar to today's elephants. This proves that the elephants could have came from the same ancestor or they could be apart of the Mammoth and Mastodon family. After looking at all this evidence I believe that the environment changed which made some of the leave and they adapted to mammoths and the others left to become mastodons and the ones that stayed are today's elephants.

Throughout time, horses have evolved as a response to environmental changes and other factors. Beginning in the Eocene, the number of horse forms increased dramatically; exhibiting a variety of distinct adaptions to different environments (lab notes). However, by the end of the Pleistocene, the diversity disappeared, leaving a single extant genus; the Eqqus. During the 55 million years in which horses are believed to be evolving, and as environmental changes were taking place, there were changes in the vegetation of North America, Eurasia and Africa, influencing distinct selective forces. As a result, natural selection produced morphological adaptions; observed in the fossil record.

Hippos are large and aquatic, like whales, but the two groups evolved those features separately from each other. We know this because the ancient relatives of hippos called anthracotheres (not shown here) were not large or aquatic. Nor were the ancient relatives

The animals we know as Mammoths (Mammuthus primogenus) are a species of ancient extinct elephant. Mammoth adults were about ten feet tall at the shoulder, with long tusks and a coat of long reddish or yellowish hair (Haynes). This is why they are sometimes described as woolly mammoths. Males weighed up to 6 tons and a newborn calf weighed about 200 lbs. (Sloane). The woolly mammoth was well adapted to its cold environment and were predominant in the

The Bush elephant has to make annual migrations to find suitable conditions, these migrations can be up to several hundred kilometers. The Bush elephants usually migrate from a permeant water source at the beginning of the rainy season, then return during the dry season (once what water holes begins to dry up). When the water is scarce the elephants will dig holes in water beds using their trucks, feet and tusks. Once enough water emerges to use their trunk to suck up the water. They usually prefer to be near water sources. The Bush elephant needs 200-300 kg of food a day and 160 liters of fresh water a day. They are herbivorous. The diet of the Bush elephant consist of: roots, bark, twigs, shrubs, roots, herbs, grass, tree foliage and some

The year is 1,002,016 and it’s scorching hot! The African Bush Elephant’s trunk has evolved to be six inches longer. The ancient elephants had a different variation of the trunk, some of them had a smaller trunk, some elephants with longer trunks. Now that there was different types of elephants natural selection came into place so, more and more of the elephants had longer trunks, but as time has passed water became scarce. As a result, the elephants with the smaller trunks in the population diminished. Since they were not able to survive. The elephant with the longer trunk were able to survive more. Now the trait will help the elephant survive since, it was able to adapt to their new dry sandy habitat since it be able to smell the water

In either species, if it is possible for the male to make body contact with the female he tries to lay his head or trunk in the elephant, on her back. After lots of
