The dream of scientists trying to bring back an extinct bird is a step closer, as described in the movie Jurassic Park.
The small clump of terror birds is a non-flying bird that lives in parts of New Zealand and was suddenly extinct in the late 13th century due to over-hunting.
Now, a research team at Harvard University has collected the genome of a terror bird that is almost completely extinct.
To do this, they extracted ancient DNA from a toe bone of a terror bird specimen preserved at the Royal Ontario Museum in Toronto.
Then, Harvard scientists put the DNA into the egg cells of a living species.
The DNA is highly fragmented, so the scientists pieced together 900 million nucleotides and matched them to specific locations in the genome.
The researchers used a new DNA sequencing method, high-throughput sequencing, to identify the nuclear genome of small clumps of birds.
The study said: "High-throughput sequencing has revolutionized the field of ancient DNA (aDNA), which promotes the recovery of nuclear DNA to better infer the evolution of extinct species, not just from mitochondrial DNA. Inferred."
Studying the nuclear DNA of small clumps of birds has allowed scientists to delve deeper into the evolutionary history of the bird.
The small clump of terror birds is part of the branch of the bird's ancient genus, and is close relatives of crickets, ostriches and crickets.
The terror birds are divided into nine types according to their size, but they are now extinct.
The small clumps of terror birds are the smallest and most common variant.
Most small clumps of birds are about 4 feet (1.22 meters) high and weigh about 66 pounds (30 kilograms), living on branches and other plants.
The New Zealand Herald stated that the small clumps of terror birds lived on the northern and southern islands of New Zealand, and that they and other terror birds were hunted to extinction before the arrival of the Polynesians.
Experts say that the work of researchers at Harvard University may make it easier for other long-term extinct species to recover from extinction.
Ben Novak, chief scientist of the non-profit Revive and Restore, said in an interview: "They can get the genome from the toes of the small clowns, because now we may be able to use their data to study other extinct birds. Species."
The genome of birds has a similar structure, which makes it possible to reconstruct other species using the genes of small clumps of birds.
Automatic Massage Foot Bath Machine
The automatic massage foot bath machine is a device that uses water and massage rollers to provide a relaxing foot massage. It usually has a basin filled with water and has built-in massage rollers that move and massage the feet. The machine may also have other functions, such as heat therapy, air bubbles, and vibration. Users place their feet in the basin and the machine provides a soothing massage that helps relieve tension and improve foot circulation. Some automatic foot massage machines also come with removable attachments for additional massage options.
