Finding embryos inside dinosaur eggs is a faster step with the creation of hybrid embryos between dinosaurs and chickens.
In the southern province of Neuquen, Argentina, scientists from the country have discovered fossilized embryonic dinosaur eggs with an age of about 70 million years.
According to the Vietnam News Agency, a correspondent in Buenos Aires, quoted on April 13 by Director of Cultural Heritage in Neuquen, Claudia Della Negra said the fossil is similar to the fossilized eggs found. previously in another area of this province.
Archaeologists are now studying embryos, teeth and skin of this fossil dinosaur egg.
Previously, researchers at North Carolina State University used 68 million-year-old DNA samples taken from soft tissue cells in a Tyrannosaurus Rex fossil to create the first healthy dinosaur embryos in millions. year.
The fossil specimen is from a pregnant tyrant dinosaur, preserved in extremely optimal conditions. This DNA is implanted in a chicken's skin cell - a relative of the tyrant dinosaur.
The 68 million-year-old DNA sample was taken from soft tissue cells in a Tyrannosaurus Rex dinosaur fossil used to create dinosaur embryos.
Linda Rushmore, a school of paleontology at the North Carolina Museum of Natural Science, said: " The similarity of T-Rex's genetic genes and chickens initially surprised us. same interest in positive results and healthy development of this pregnancy ".
This embryo is not entirely a dinosaur, but actually an individual created between T-Rex and chicken , according to Helmut Hans Fraser, a molecular biologist at the school.
" We found that embryos developed at an unusual rate compared to conventional chicken embryos. It is now 65 times larger than the embryo of chickens after only 3 days of development, and it grows very fast, which is what makes me interested, "Helmut added.
We often think of T-Rex as a giant reptile that looks like a crocodile on two legs, but in fact, their closest relatives are birds and in the dinosaur world, T-Rex also just the size of a chicken.
Thereby, the discovery of embryos inside dinosaur eggs is a faster step with the creation of hybrid embryos between dinosaurs and chickens. Not far away, will scientists be able to revive dinosaurs?
In 2015, geneticist George Church and colleagues succeeded in using CRISPR gene editing technology to install genes that determine mammoth physique into ordinary elephant skin.
