Okahandja soul singer David MCorney (33) is making his dream come true, by singing his way to the top of the first ever ‘Voice of Namibia’ competition, which is heading to the finishing line next week. From 15 hopefuls, David has emerged as a finalist, and is the “last man standing”, against three female country singers, with song choices from the likes of Michael Buble, Cool & the Gang “Celebration” to mention some while complementing his vocal capabilities. His recent live performance in Walvis Bay was just enough to get people craving more of him, as he wowed the judges and audience with his rich voice that took you to church and back. David made the stage his own, as he hit all the notes whilst belting out a goose bumps rendition of Josh Grobin’s Remember when it rained. He is a natural born artist with a strong gospel spin as well as old time R&B influence.
The Okahandja born father of two boys, has been singing since he can remember, and was part of a group called ‘Vocal Dynamics’ which participated in the 2012 Tustco Star Performer competition and won. The group which gained momentum, also travelled later that year to an arts convention to Orlando Florida, USA, and won the competition – flying high the flag for Namibian artists. David says he has come a long way in the entertainment scene, yet despite a lapse in his music career over the past few years, he plans on taking it up again and going guns blazing into the recording studio with a solo album – which he says will include some Afrikaans hits.”The Voice of Namibia competition has really given me the encouragement to continue with my music, as well as a platform to showcase my singing capabilities, he adds.
A telesales marketer by day and musician by night, David is preparing himself with two fresh recordings for the final round of judging, with the winner being announced next week. Meanwhile, competition organiser, Alinda Lu’Mar, describes David as a “gentle and kind person with an amazing talent, who has really impressed the judges and the public with his rich and powerful voice.” Lu’Mar adds that the four finalists are making use of smaller recording studios to present their work in a professional manner, and this has been a wonderful opportunity for all of them to shine.
“I believe the top four are really our top singers and we are really proud of them,” she said. “But in the end it will be the public who will vote in our winner.”
The top three ‘Voice of Namibia’ finalists are: David McCorney, Joharetha Nel, and Claudine Nelson while Jo-Ann Dobson was saved by the judges. The finalists have all been presented songs written by Cat Lamondt of Lamondt International Records, which will include an Afrikaans song, which will be uploaded on the ‘Voice of Namibia’ facebook page for the public to vote. The winner of the competition will be announced on March 24, with prizes including a recording contract from Lamondt International Records, a professional microphone, a week-end for two at Indulge Guesthouse in Swakopmund.
We rarely portray Neanderthals, our close relatives, as telegenic. Museum exhibits give them wild tangles of hair and Hollywood reduces them to grunting unsophisticates. Their skulls suggest broad faces, tiny chins and jutting brows. But to mock Neanderthals is to mock ourselves: Homo sapiens had lots of sex with Homo neanderthalensis. Neanderthal genes supply between 1 per cent and 4 per cent of the genome in people from homelands on several continents, from Britain to Japan to Colombia.
DNA from another humanlike primate, the Denisovans, lurks in modern genomes, too. A molar and a chip of pinkie bone found in a Siberian cave provide what little information we have about this species. DNA extracted from the fragments previously revealed cross-species breeding. Yet a new study in the journal Cell shows that the ancient hanky-panky did not stop in Siberia: humans who travelled across South Asia mated with a separate group of Denisovans as well.
“This is a breakthrough paper,” said David Reich, who studies ancient DNA at Harvard University and was not involved with the study. “It’s a definite third interbreeding event,” one that adds to the previously known Denisovan and Neanderthal mixtures.
Humans and Neanderthals divided into separate groups as far back as 765,000 years ago. Denisovans and Neanderthals were closer cousins who split more recently and then vanished – perhaps because we absorbed their lineages.
A team of scientists, led by University of Washington biostatistician Sharon Browning, took an approach that Mr Reich called a “technical tour de force”. In the new study, Browning and her colleagues examined more than 5,500 genomes of modern humans from Europe, Asia and Oceania, looking for any possible archaic DNA.
“We’re looking for segments of DNA in an individual that look quite different from the rest of the variation in the population,” Ms Browning said.
After the team fished out the DNA variations, the researchers matched the segments to Denisovan and Neanderthal sequences, known from samples in Siberia’s Altai Mountains.
All groups studied, from British and Bengali people to Peruvians and Puerto Ricans, had a dense cluster that closely matched the Altai Neanderthals. Some populations also had a cluster that matched the Altai Denisovans, which was particularly pronounced in East Asians.
The surprise was a third cluster – not like the Neanderthal DNA and only partially resembling the Altai Denisovans. This, the authors concluded, was a second and separate pulse of Denisovan genes into the DNA blender.
“The geography is quite suggestive,” Ms Browning said. The authors hypothesise that, as ancestral humans migrated eastward, they came across two different Denisovan populations. One pulse, to the north, shows up in people from China, Japan and Vietnam.
The other Denisovan pulse appears to the south. “Maybe it was down in the southeast corner of Asia,” Ms Browning said. “It could possibly have been on an island en route to Papua New Guinea, but we clearly don’t know.”
Mr Reich said he would not be surprised if methods similar to this one revealed additional mixtures. “I am sure there are others,” he said, considering the wide range of archaic groups across Eurasia.
Ms Browning plans to continue to hunt for additional mixtures, including among people of African descent who were excluded from this study because the warm continental climate makes finding archaic DNA a challenge.
“We’re interested in other populations around the world, especially Africa,” she said.
