South Africa: Low Levels of Genetic Diversity Are Putting Great White Sharks At Risk

… creatures. Research on the DNA of white sharks around the South African coastline shows that the population has extremely low geneticdiversity. This finding holds serious implications for their survival and more analysis is being done to try and understand this unexpected outcome and predict its consequences for the future of the species. What genetic diversity tells us Genetic diversity is an important indicator of the health status of a population in the wild: the higher the diversity, the …

Scientists rush to freeze plant DNA before ‘sixth extinction’ – BBC News

By Jane O’Brien, BBC News, Washington | July 9, 2015 As the world enters into a sixth great extinction, scientists are racing against the clock to save genetic evidence from plants around the world. An ambitious project launched Wednesday to collect the genomes of the planet’s major plant groups within the next two years and put them into deep freeze. The project is part of the Global Genome Initiative, which aims to gather and preserve the DNA of all life on Earth in cryo-storage …

Genome Study Brings Woolly Mammoth DNA Back From the Dead / Sputnik International

From sputniknews.com | July 4th, 2015 A study found the genetic adaptations which allowed woolly mammoths to endure severe Arctic conditions, raising the prospect that the animals could one day be resurrected. A study which sequenced and compared the DNA of Asian elephants and woolly mammoths has identified the traits that allowed the extinct species to survive extreme temperatures, a finding which also raises the prospect that the genetic information could one day be used to bring the …

Could human imagination save us from extinction? | Andrew Simms | Environment | The Guardian

… trends we’ll be lucky to see out the millennium. Some of those other human species we seem to have absorbed, such as the Neanderthals whose DNA we carry, while others we probably drove to extinction, directly or inadvertently. Scratching for positives you could argue that at least we don’t discriminate over who or what we push over the edge, including ourselves. Is this, counter-intuitively what we will be remembered for – if there is anything or anyone else to remember us? Not our art, …
