Could it be possible to revive extinct species, as in Jurassic Park?
A short answer: In insects, it is quite likely that it can be difficult for larger, older animals. Scientists have successfully insulated DNA from 120-135 million years Weevil found in the Lebanon amber, intensified by polymerase chain reactions (PCR) and sequential. Not the whole genetic code, but its parts. This genetic information has been compared with modern weeviles for phylogenetic analysis. It is not a revival of extinct species, but it is a very important step in this direction.
There are a number of technical challenges when trying to revive extinct species, but none of them seems to be impossible to overcome. The hardest step is to find quite intact DNA. Because Amber is an organic and seal of insects in an airtight cover, the degradation of genetic material is relatively slow. There are few in typical fossils, if any organic material, because fossilies are not organic material alone, but inorganic muddy substances that replace organic material when decays.Until recently, in 2005, it was assumed that fossilization had always replaced the original material, but the discoveries of soft tissue Tyrannosaurus Rex, including the detection of the original collagen proteins, increased this common wisdom.
reviving extinct species would require finding large parts of the original genetic material. For Pleistocene species, such as Mammoths, cave bears, terrible wolves and even Neanderthals, there is a soft tissue, and some scientists have even made efforts to sequence. This often requires multiple samples because no individual sample is likely to contain a complete sequence of non -contaminated DNA. In the Jurassic Park, the gaps in the dinosaur DNA were replaced by DNA frog segments, but this is problematic because it assumes that scientists knew which dinosaurs were related to which frogs they joined. As geneticated, it will be so. String easier to make these estimates even if it is truthSimilar that considerable parts of the original genetic material will be required.
There is a consensus between scientists that the revival of the Pleistocene species, especially non -Sanderthals, is completely feasible and only a matter of time. If the entire genome can be sequentially sequential, it can be synthesized and injected into a fertilized egg cell on a related species (such as birds), then grown in an artificial egg or womb. Previously, it was considered a challenge to create a suitable artificial egg, but recently scientists have been developing an environment that should work to increase almost any embryo.
Before we see the revival of ancient species, such as dinosaurs, we will probably see species from the Pleistocene. The possibility of reviving extinct species raises many ethical questions, but human curiosity is so great that it seems unlikely that the technology will be detained for a long time if it is technologically feasible.
