Genomes in Flux: New Study Reveals Hidden Dynamics of Bird and Mammal DNA Evolution

Kapusta_MegBenhase_Hummingbird_Bats_large_crop.jpg

Evolution is often thought of as a gradual remodeling of the genome, the genetic blueprints for building an organism. But in some instance it might be more appropriate to call it an overhaul. Over the past 100 million years, the human lineage has lost one-fifth of its DNA, while an even greater amount was added, report scientists at the University of Utah School of Medicine. Until now, the extent to which our genome has expanded and contracted had been underappreciated.

Genomic Tools for Species Discovery Inflate Estimates of Species Numbers, U-Michigan Biologists Contend

Increasingly popular techniques that infer species boundaries in animals and plants solely by analyzing genetic differences are flawed and can lead to inflated diversity estimates, according to a new study from two University of Michigan evolutionary biologists.

Big Data Shows How What We Buy Affects Endangered Species

130082_web.jpg

The things we consume, from iPhones to cars to IKEA furniture, have costs that go well beyond their purchase price. What if the soybeans used to make that tofu you ate last night were grown in fields that were hewn out of tropical rainforests? Or if that tee-shirt you bought came from an industrial area that had been carved out of high-value habitat in Malaysia?
