Building a Woolly Mammoth out of an Asian elephant begins with identifying the genes in the mammoth genome that code for three essential adaptations:. The Harvard-based team , led by Dr. To date a number of genes have been successfully rewritten into Asian Elephant cell lines, generating increasingly mammoth-like cells with each precise edit. Mutations for mammoth hemoglobin, extra hair growth, fat production, down to nuanced climate adaptations such as slightly altered sodium ion channels in cell membranes have already been engineered into fibroblast cell lines. For example, the iPSCs will be developed into red blood cells. The oxygen carrying capacity of these blood cells can be tested under varying temperatures and stress conditions without ever producing an animal.

From expressing grief to respecting hierarchy, elephants have much in common with us. In fact, the resemblance was noticed even in ancient times. Historically, elephants have also played an important role in warfare. Now, however, things have changed.
Elephants and their recently extinct relatives (mammoths, mastodons) were They also appear as frequent subjects in art dating to about 30, B.C. in Europe.
Today, we are praising Match. Three out of four venues studied found conservation and welfare issues including damage physically and psychologically to elephants. Elephant-washing activities as shown in the ad force elephants to remain in water longer than they would naturally and reinforce demand for elephants in captivity. The constant presence of strangers requires elephants to be controlled by keepers through harsh obedience training from a young age that includes severe restraining, pain and discomfort.
Elephants forced into direct contact with people are anything but free. Taken from their natural environments and exploited for entertainment and profits, captive elephants tamed for entertainment never truly experience a life free from suffering and cruelty. Close interaction with captive elephants also regularly leads to injuries and fatalities of keepers and sometimes of visitors.

Poaching is on the rise — most illegal ivory comes from recently killed elephants
Although this elephant — the Eurasian straight-tusked elephant Palaeoloxodon antiquus — likely died of old age, meat-eaters promptly devoured it; bite marks on its bones suggest that carnivores feasted on the dead beast, and flint flakes and bone tools found near the elephant indicate that humans scavenged whatever was left, the researchers said. Related: Elephant images: Largest land animals.
The elephant died on the western side of a vast lake, a hint that it perished from natural causes. In addition, the elephant, a female, had worn teeth, suggesting it was old when it died, he said. But this new find is by far the most complete.

Worrying news has recently come to light: hundreds of elephants have been found dead in Botswana, and as yet, there is no clear cause of death. But as an expert in elephants and their conservation, I believe we can at least rule out a few possible answers. Here’s what we do know: the first deaths were reported in March, but significant numbers were only recorded from May onwards.
To date, it’s thought that the death toll stands at nearly elephants of both sexes and all ages. Most of the deaths have occurred near the village of Seronga on the northern fringes of the Okavango Delta, a vast swampy inland region that hosts huge wildlife populations. Many of the carcasses have been found near to water. Of those discovered so far, some lay on their knees and faces rather than on their side , suggesting sudden death, although there are also reports of elephants looking disoriented and even walking in circles.
The tusks of the dead elephants are still in place and, as yet, no other species have died under similar circumstances. Botswana has long been a stronghold for Africa’s remaining , elephants, boasting a third of the continent’s population. While elephant numbers have widely declined in recent decades, largely due to poaching, Botswana’s population has grown. However, this growth has been outpaced by the ever-increasing human population.
With more elephants and more people, competition for space has escalated and increasingly, elephants and people find themselves at odds.

Abstract — The article investigates the occurrence of elephants in the environment of the Orontes River System during the Bronze Age. Special attention is given to the find contexts and its relevance for reconstructing the organisational frame of elephant hunts. The former natural conditions of the Ghab Basin in the central Orontes Valley are studied in detail in order to demonstrate the quality of this region as a particularly favourable elephant habitat.
Related to the archaeological data, the former environmental conditions of the Orontes Valley will be examined in order to assess the suitability of the area as a habitat for elephants. The northwest wing stands out for its perfectly well-preserved walls and doorways. This excellent state of preservation is due to the positioning of the construction on the western slope of the palace terrace, which made it possible to set the building at a lower level into the sloping terrain.
In consequence, the rooms of the northwest wing formed a lower storey of the palace, situated significantly below the floor level of the main sector of the palace building. Above the rooms of the northwest wing there must have been an upper storey, at roughly the same height as the rest of palace.

In Sanskrit poetry, people and elephants live harmoniously in a shared natural world, where elephants enhance the aesthetic pleasure of the landscape by augmenting almost all of the human senses. In fact, throughout the history of South Asia, elephants were valued profoundly for their might and majesty, embodying royal power and inspiring comparisons to kings and deities.

Reservations are required to visit. Zoos play an important role in the conservation and study of elephants, as well as many other endangered species. Many scientists believe the Asian elephant could become extinct in the wild by the middle of the next century, if current habitat destruction trends continue. Given the uncertain future for elephants in the wild, captive management programs are becoming increasingly important to the survival of the species.
These programs can create secure reservoirs of animals and their gene pools to re-establish wild populations that have become extinct. They can also reinforce remnant wild populations debilitated by genetic and demographic problems. In addition, zoos also have a unique opportunity to contribute to the body of scientific knowledge about elephants, knowledge that is nearly impossible to gain from elephants in the wild. Because of our ready access to captive animals, and the trusting relationships built between elephants and their keepers, zoos have amassed valuable data on elephant physiology and diseases, nutritional requirements, behavior including memory , genetics and reproduction.
In addition, the captive breeding of both Asian and African elephants has been more successful in recent years because of increased efforts in natural reproduction and technical advances in assisted reproduction. We are proud that Zoo observations and studies of captive elephants are adding to the growing body of zoological data on elephants, and are being used to contribute to global conservation efforts on behalf of the species as a whole.
So how do you go about breeding endangered species? When it comes to elephants, it’s no simple matter. Not only does a Zoo need adequate facilities and staff, but it also needs to know which elephant to breed with which. This is important in preventing inbreeding and loss of genetic variability in the species.

Being the largest land mammals, elephants have very few natural enemies and are active during both day and night. Compared with those of diurnal and nocturnal animals, the eyes of elephants and other arrhythmic species, such as many ungulates and large carnivores, must function in both the bright light of day and dim light of night.
Despite their fundamental importance, the roles of photosensitive molecules, visual pigments, in arrhythmic vision are not well understood. During the day, therefore, elephants seem to have the dichromatic color vision of deuteranopes.

This seemed unlikely, as authorities had just seized 1,pounds of ivory from his shop and home in Togo. Was he lying? Normally, authorities would have no way of knowing. Now, the same powerful tool has been applied not just to a single case, but to hundreds of samples of ivory from around the world. The analysis has revealed that most of the ivory entering into the illegal trade today comes from elephants killed less than three years ago , researchers report in Proceedings of the National Academy of Sciences.
Some have suspected that older material is leaking out of government storage facilities, or that traders hoard tusks for many years before sneaking them onto the black market. Others insist that the ivory currently flooding markets in Asia must be from recently killed animals, given the rate at which elephants across Africa are being slaughtered. To settle this debate, Cerling and his colleagues used carbon dating, a well-established method that relies on radiocarbon produced by nuclear tests carried out in the s and s.
In that time period, the U. The isotope has been slowly changing since then, and scientists refer to compiled measurements of its concentration over time as the bomb curve. Measuring the amount of carbon in a biological sample and then matching it to corresponding values in the bomb curve tells scientists when the tissue formed, plus or minus six months.

The African elephant Loxodonta is a genus comprising two living elephant species , the African bush elephant L. Both are herbivores and live in groups. They have grey skin and differ in the size of their ears and tusks , and in the shape and size of their skulls. Poaching for the illegal ivory trade is a threat in several range countries as well.
Loxodonta is one of two existing genera of the family Elephantidae.
20It has been possible to date the Maraş elephant bones through two radiocarbon dates. One gives a calibrated date of bc, the other a date between.
All rights reserved. Radiocarbon dating, made possible by open-air nuclear tests shown in newly declassified videos, is helping scientists pinpoint when elephants were slaughtered. It has long been known that radioactive isotopes in the atmosphere have made carbon dating of all kinds of materials possible. Radioactive carbon released from nuclear bomb tests during the Cold War is one way of dating more recent materials.
That method is now being used to help fight the illegal trade in elephant ivory. Thure Cerling , a University of Utah professor of biology, geology, and geophysics, and colleagues, published a study in late that demonstrates how radiocarbon dating, combined with genetic analysis of elephant tusks, can yield valuable clues as to when and where elephants are being poached.
The illegal ivory trade is driving elephants toward extinction.
In India, few animals carry the kind of cultural symbolism that elephants do. Human-elephant interaction boasts a rich history dating back centuries. It is but natural that such a long association would also have encounters that do not end happily. The Hassan region, however, has been beset by human-elephant conflicts for years with a number of these encounters resulting in fatalities. But, thanks to resilient conservation efforts and smart application of technology in recent months, Hassan could soon be at peace with its elephants.
A fertile landscape comprising fragmented forest patches, coffee plantations and paddy fields, Hassan offers a rich and conducive topographical mosaic for elephants, a habitat generalist species known for travelling long distances.
This is how the ancient humans may have discovered the elephant’s Researchers have found the remains of at least 10 elephants dating to.
Various Pleistocene dwarfed elephants known from the islands of Celebes, Flores and Timor in the eastern part of the Malay Archipelago are described and their relationships considered. It is evident that these pygmy forms arose independently on each of the islands as a result of isolation and genetic drift favouring small size as in the better-known cases of the Mediterranean and Santa Barbara Channel Islands dwarf species.
The dispersal possibilities of elephants are discussed; the conclusion must be drawn that geographic spacing has been the prime factor in species formation. Idle or fruitless speculations about ecological or other non-morphological species criteria have been omitted; the taxonomy of proboscideans as far as needed in the present context is however elucidated.
It is pointed out that wherever we find pygmy elephants we have also giant rodents; in these presumably small isolated populations giganticism in small rodents appears to have been as advantageous to the animals as is dwarfing in elephants. As neither the exact date of colonization nor that of the eventual extinction brought about by man or otherwise is known, we have no means of knowing how many generations were involved; it is, however, likely that evolutionary velocity has been higher under these conditions than is usual.
