Recreate ancient people

From isolating the DNA sequence of the ancient Neanderthal, recreating the blood vessels of a dinosaur species, optimists argue that, at this rate, scientists will recreate extinct creatures in past.

One of the highly regarded scientific works in 2006 was " DNA reconstruction " by German scientists. It is ranked second in the most important works of the year by Science.

Over the past decade, German scientists have isolated the DNA sequence of the ancient Neanderthal people from a skull dating to 40,000 years old. The success of this work has contributed to answering the genetic changes of people today.

Thus, the leaps of biotechnology have opened up the prospect of not only studying people in the distant past but also able to recreate those people in the flesh.

Previously, American scientists have also recreated the lifeblood of a dinosaur species living 68 million years from our time. They isolated the protein, comparing the protein sequencing sequence to find out the relationship of dinosaurs with other prehistoric beasts and living species today.

In 2005, British scientific journal Nature published, a British research group invented a new technique to retrieve DNA from 200 g of bone at a mammoth burial site, in Siberian permafrost. This technique is called multi-molecule chain reaction, which can copy 46 continuous code sequences to help rearrange to create an image of the mitochrondria, the energy supply part of the animal's DNA.

Optimists believe that, on this momentum, scientists will recreate extinct creatures in the past. Imagine the grandfather's launch ceremony Neanderthal lived 40,000 years away from us, along with a mammoth that lived more than 10,000 years away from us and a dinosaur living 68 million years away .

But assuming that's true, how are we, descendants, going to behave with our ' ancestors '? And how can ' ancestors ' adapt to modern society, or do we just treat them as a scientific product?

As for dinosaurs and mammoths, reproducing them seems a bit luxurious while natural resources such as forests and wildlife in the red book are in alarming state because of child abuse. people. Recreating extinct creatures is the dream of future scientists, but according to environmentalists, what needs to be done rather than protecting nature so that no more plants and animals are gone strains.
