Is it possible to resurrect prehistoric animals?
If we refer to dinosaurs as depicted in the film Jurassic Park, it seems that currently it is impossible not to resuscitate. While experts are very excited to think that in future it may be.
Apparently it has been able to recreate a living ... but very simple ... is actually a bacteria. Pour bacteria (Mycoplasma mycoides) is the first time you create a synthetic life form. To achieve this, the researchers built a machine in his laboratory every one of the basic units of DNA of the bacteria 'Mycoplasma mycoides' and assembled as if it were a Mecano. Once assembled the intricate puzzle, emptied a cell of another species of bacteria and introduced the synthetic genetic code in the cell container. And that's it ...
But of course, there are limitations:
1st - The Pour bacteria is very simple, basically a membrane genome, but in more complex organisms the DNA is packaged in the nucleus. And no one, until now, has been able to empty the heart and inject DNA into the interior.
2 - DNA sequences tend to deteriorate over time, and it is very difficult to draw a complete map of animals that lived millions of years could be the known T-rex. However there are other prehistoric animals, and extinct, are possible candidates ... as recently extinct and has obtained a DNA map comlete. Saber-toothed tigers, mammoths, cave bears, Tasmanian tiger, woolly rhinoceros, giant sloth and even our cousins the Neanderthals. All of them disappeared less than 100,000 years ago.
3 - There must be akin to a living animal which wants to revive, for example, to the mammoth elephant would be required to insert the embryo. But of course, to resurrect the kind of Neanderthal what it would take would be a woman. And this will bring much discussion and many different opinions, which I think could be done though, many voices that would oppose it.
4 - The environmental conditions of animals are now missing, in some cases, nonexistent. And basically serve as scientific purposes. There are no dams Sabretooth or frozen grass to keep Mammoth.
Well, I always think I conclude with this question: If you could resurrect a Neanderthal, what do you think think a Neanderthal resurrected in our world?
Imagine the world's largest wolf, and now doubling in size, finally give steroids to duplicate the musculature. Throw in claws bigger than a grizzly with a strong legs to run and reach high speeds ... That leaves us? As a predator that existed from the mid-Oligocene and early Miocene. His name was Amphicyon ingens (dog ambiguous) or commonly known as Bear-dog.
This prehistoric beast could be up to three meters and weigh up to 400 kg. Given its size, you might think was not very fast, but do not be fooled, it is thought that hunted their prey in ambush and surprised with a quick career. The smell was due to an as refined as a bloodhound and a fine ear. Type of game similar to the great bears today. He could hunt animals as robust as the old giant sloths or rhinos.
He lived in Europe and Asia and later introduced in North America by the Bering Strait (humans migrated from Asia to the Americas through the strait, possibly taking advantage of a glacial period and the freezing of the Sea) competition in North America other carnivorous even more ... the Daeodon or "terrible pig."
At the end of the Cretaceous period in what is now South America, approximately between 83 and lived 80 million years ago the "Abel's lizard" or Abelisaurus. With a skull up to a meter and sharp teeth this carnivorous predator of between 7 and 9 meters (25 to 30 feet)long and weighed about 3000 kilograms, were living with other predators such as known Tyrannotitan or Carnotauros, fierce competitors for the same prey as old tyrannotitanes patients. The Carnotaurus, was probably a abelisaurid early, scientists assume that Abelisaurus also had front legs short and slender limbs.
The discovery of Abelisaurus is important because it sheds light on many theropods (carnivorous diet and walking biped with three fingers to the front and provided with sharp claws) than the southern hemisphere that were very different from their relatives in the northern hemisphere. This was the result of the separation of land masses of North and South that began in the Jurassic period.
Not go into the morphological differences ... anyone who wants to know them I invite you to search Wikipedia.
