“We have no intentions of breeding dinosaurs,” say researchers extracting DNA from insects preserved in resin



Researchers who extracted genetic material from an insect preserved in resin, for the purpose of a recently published study, are aware of the Jurassic Park harmonics for what they do, but assure the public “we do not intend to breed dinosaurs. ” So far, scientists have not been able to conclude that ancient DNA can viably last for millions of years inside insects preserved in resin, thus dampening the hope of real life John Hammonds everywhere. A group of European researchers is specifically investigating how long DNA can last in insects preserved in resinous materials – if you will, the shelf life. These researchers have successfully extracted genetic material from two-year and six-year resin samples and hope that these new methods can be used for future studies of much older samples.

“However, we do not intend to breed dinosaurs,”

; said Dr. Mónica Solórzano-Kraemer from the Senckenberg Research Institute and the Natural History Museum. “Rather, our current study is a structured attempt to determine how long the DNA of insects enclosed in resinous materials can be preserved.”Previous attempts to extract ancient DNA from a million-year-old or hundred-thousand-year-old fossil resin have been criticized or considered unsuitable for genetic research as “the result of modern environmental pollution and due to lack of reproducibility.”

As recently published in the journal PLOS, the researchers said, “Our goal is far from starting an uncontrolled search for aDNA in amber as it was before, but to start solving basic aspects of DNA preservation in resin and searching from the most modern samples. to the old ones, step by step. We conclude that it is therefore possible to study genomics from resin-embedded organisms, although the deadlines still need to be set. “

In other words, they can now successfully extract genetic material from samples preserved in amber, but it is unclear whether genetic material can actually last for millions of years in such a state (unlike in other fossil remains). This study has proven that genetic material can last at least up to six years, but could ancient DNA – OK, let’s just say, dinosaur DNA – actually survive in petrified resin for millions of years?

Right now, the answer seems to be no or at least very unlikely, but these researchers hope to determine how long genetic material can be preserved in future studies using the modern genomic techniques used in this study.

The best deaths in the Jurassic Park movies

“Our experiments show that water in the inclusions is preserved much longer than previously thought. This can also affect the stability of the genetic material. Extraction of functional DNA from millions of years old amber is therefore quite unlikely,” said Dr. Solórzano -Kraemer.

But are these researchers so preoccupied with whether they could or not, they did not stop to think whether they should? Well, that they are hip to Jurassic Park by all means suggests that they do not want birds of prey back to life either.
