New York: The first people to reach the Americas came from Siberia, now in Russia, in a single group around 23,000 years ago, at the height of the last Ice Age, says a new study.

After reaching Alaska, they apparently hung out in the north – perhaps for thousands of years – before spreading throughout North and South America, said the study based on genomic analysis.

The findings dispel the popular idea that Polynesians or Europeans contributed to the genetic heritage of Native Americans.

The study revealed that the the first people to reach the Americas used a land bridge between Siberia and Alaska called Beringia.

“There is some uncertainty in the dates of the migration and the divergence between the northern and southern Amerindian populations. But as we get more ancient genomes sequenced, we will be able to put more precise dates on the times of migration,” said one of the study authors Yun Song, associate professor at University of California, Berkeley.

The analysis, using the most comprehensive genetic data set from Native Americans to date, was conducted using three different statistical models.

The data consisted of the sequenced genomes of 31 living Native Americans, Siberians and people from around the Pacific Ocean, and the genomes of 23 ancient individuals from North and South America, spanning a time between 200 and 6,000 years ago.

The international team concluded that the northern and southern Native American populations diverged between 11,500 and 14,500 years ago.

The southern branch peopled Central and South America as well as part of northern North America. The findings will be presented in the forthcoming issue of the journal Science.

“The diversification of modern Native Americans appears to have started around 13,000 years ago when the first unique Native American culture appears in the archaeological record: the Clovis culture,” said Rasmus Nielsen, a professor at the California university.

“We can date this split so precisely in part because we previously have analysed the 12,600-year-old remains of a boy associated with the Clovis culture,” Nielsen added.

NEW DELHI: Over the years, India has emerged as a superpower to reckon with. The warfighting capabilities with cutting-edge technological advancements have manifold increased India’s potential at the global level. The man behind the success of India’s missile program is none other than the Late President APJ Abdul Kalam. The BrahMos Aerospace CEO, Sudhir Mishra has also credited the success of Indian missile program to Abdul Kalam.

The deadly BrahMos is a stealth supersonic cruise missile that can be launched from submarines, ships, aircraft or land. The strike-range of the missile is over 290 km and is ranked one of the most advanced missiles of this generation.

The project was a joint venture between Republic of India’s Defence Research & Development Organisation (DRDO) and Russian Federation’s NPO Mashinostroeyenia. The both these organization have together formed BrahMos Aerospace Private Limited. The name of the missile is taken out from the names of two rivers, the Brahmaputra of India and the Moskva of Russia.

Let’s take a look at some of the facts related to BRAHMOS Missile:

  1. BrahMos missile is the world’s fastest cruise missile in operation. The missile can travel at speeds of Mach 2.8 to 3.0.
  2.  The missile can zoom at a very low-cruising altitude of 10 meters at the terminal phase and can hit the target with pin-point accuracy.
  3.  BrahMos missile was first test-fired in 2001, at the Integrated Test Range (ITR), Chandipur and after that, the missile is tested by DRDO more than fifty times for various platforms.
  4.  The land launched and ship-launched versions are already inducted into service with air-launched and submarine-launched versions in their final phases of the trial.

  5. DRDO is also experimenting with a hypersonic version of the missile. It is expected that the new variant could attain a speed of Mach 7.
  6.  The land-attack version of BrahMos missile has been developed in many advanced forms of Block I, Block II and Block III variants.
  7.  The trajectory and speed of missile is very unique and thus makes it very hard to detect or stopped. The BrahMos can travel at a low altitude of 10 meters and is also known as terrain hugging missile.
  8.  As per to reports, it is believed that Russia and India are aiming to produce 2000 such supersonic cruise missile in the time frame of 8-1-0 years.
  9.  BrahMos missile is very much advanced in every concept as compared to much hype US’ Tomahawk missile. BrahMos is 4 times larger than Tomahawk missile and 32 times more powerful than it.

    Recently, Brahmos missile has been integrated in India's front-line aircraft, Sukhoi 30 MKI. Wikimedia Commons

  10. DRDO has already started the work to integrate the Brahmos supersonic cruise missile on 40 Sukhoi combat aircrafts. BrahMos was successfully test-fired from Sukhoi on November 22. Sukhoi’s are counted as the most potent aircrafts in the world.
