Bacteria Take Up Dead DNA, Scrambling Evolution
November 20, 2013
It's not just horizontal gene transfer that can obscure evolutionary history. Scientists have found bacteria recycling fragmented DNA from long-dead organisms. The impact on evolutionary theory could be substantial.
Is This Plant Really 30,000 Years Old?
February 20, 2012
A plant said to be 30,000 years old has been brought to life in Russia. A team resurrected a fruit from a rodent burrow in Siberian permafrost, getting it to grow into a whole plant that produces viable seeds. This is now the oldest age claim, by an order of magnitude, for plant material made to live again. Other scientists are startled that plant material could remain viable for so long, since cells have to repair their DNA continually. Other botany news bring different problems to evolutionary theory.
