Extinction Means Less Mammal Poop To Fertilize The Earth

… the capacity for land animals to carry nutrients away from “hotspots” has fallen to eight percent of what it was at the end of the last ice age. The capacity of whales, and other marine mammals to carry nutrients such as phosphorous from the deep sea to more shallow waters has been reduced by about 75 percent. In the past animals were not believed to be vital for nutrient transfer, but this new research demonstrates the animals are crucial for the “distribution pump” of …

Woolly mammoth skin’s living cells could help bring the beast back to life 

… more than 10,000 years has given Russian scientists fresh hope of being able to clone the extinct giants. The fragments of skin were discovered along with other remains from six of the ice age creatures. Researchers are now examining it for signs of ‘living cells’ in a special laboratory set up as part of attempts to resurrect the beasts. They are working with researchers in South Korea who have been developing techniques to clone animals on the project. Semyon Grigoryev, who headed …

What the animal world would look like if humans never existed

… during the last ice age was mostly due to the spread of humans rather than climate change. “Last year we published another study, which along other studies, clearly suggested that humans were a massive driver in the large extinction which occurred near the end of the last ice age,” lead study author and postdoctoral fellow in bioscience Soren Faurby told Foxnews.com. “During this work we started talking about just how big the effects of humans was and how the world would have been …

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 …
