Scientists are hoping to revive birds that have been extinct for 700 years.

Scientists are one step closer to trying to bring back an extinct bird, as described in the movie Jurassic Park.
, a bird that can't fly, lives in parts of New Zealand and suddenly became extinct in the late 13th century due to over-hunting.
Now, a team of researchers at Harvard University has collected the genomes of almost extinct bird-fearing birds. To do this,
extracted ancient DNA from a toe bone of a bird-fearspecimen specimen preserved at the Royal Ontario Museum in Toronto.
, Harvard scientists then put DNA into the eggs of a living species.
the DNA was highly dispersed, so the scientists cobbled together 900 million nucleotides and matched them to specific locations in the genome.
researchers used a new DNA sequencing method, high-throughput sequencing, to determine the nuclear genome of small flocks of bird-fearing birds. "High-throughput sequencing has revolutionized the field of ancient DNA (aDNA), facilitating the recovery of nuclear DNA to better infer the evolution of extinct species, rather than just from mitochondrial DNA,"
the study said.
" study of the tiny DNA of the small clump of fearbirds allowed scientists to study the bird's evolutionary history in greater depth.
small clumps of birds are part of the ancient jaw branch of the birds, with ostrich, ostrich and ostrich being close relatives.
birds are divided into nine species according to their size, but are now extinct.
and small clumps of bird size is the smallest and most common variant. most of the
are about 4 feet (1.22 meters) tall and weigh about 66 pounds (30 kilograms) and depend on branches and other plants.
the New Zealand Herald, the small clumps of birds lived on islands in new Zealand's north and south, and were hunted to extinction before the Polynesians arrived.
experts say the work of researchers at Harvard University may make it easier for other long-extinct species to recover from extinction. "It's a big deal that they can get the genome from the toes of small clumps of bird, because now we might be able to use their data to study other extinct bird species," Ben Novak, chief scientist at the
nonprofit Revive and Restore, said in an interview.
" bird genomes have similar structures, which makes it possible to reconstruct other species using the genes of small clumps of bird-fearing birds.
