Oldest known fossilized skin is 21 million years older than previous examples      (via sciencedaily.com)     Original source 

Researchers have identified a 3D fragment of fossilized skin that is at least 21 million years than previously described skin fossils. The skin, which belonged to an early species of Paleozoic reptile, has a pebbled surface and most closely resembles crocodile skin. It's the oldest example of preserved epidermis, the outermost layer of skin in terrestrial reptiles, birds, and mammals, which was an important evolutionary adaptation in the transition to life on land.

Largest diversity study of 'magic mushrooms' investigates the evolution of psychoactive psilocybin production      (via sciencedaily.com)     Original source 

The genomic analysis of 52 Psilocybe specimens includes 39 species that have never been sequenced. Psilocybe arose much earlier than previously thought -- about 65 million years ago -- and the authors found that psilocybin was first synthesized in mushrooms in the genus Psilocybe. Their analysis revealed two distinct gene orders within the gene cluster that produces psilocybin. The two gene patterns correspond to an ancient split in the genus, suggesting two independent acquisitions of psilocybin in its evolutionary history. The study is the first to reveal such a strong evolutionary pattern within the gene sequences underpinning the psychoactive proteins synthesis.

How did the bushpig cross the strait? A great puzzle in African mammal biogeography solved by genomics      (via sciencedaily.com)     Original source 

Africa has a huge diversity of large mammals, but their evolutionary relationships and movement across the continent over time often remain a mystery. A new scientific study sheds light on longstanding questions about the interplay between evolution and geography in one of these mammals, namely the iconic African bushpig, and helps settle a major question regarding prehistoric human activities shaping biodiversity patterns in Africa.

Evolution is not as random as previously thought      (via sciencedaily.com)     Original source 

A groundbreaking study has found that evolution is not as unpredictable as previously thought, which could allow scientists to explore which genes could be useful to tackle real-world issues such as antibiotic resistance, disease and climate change. The study challenges the long-standing belief about the unpredictability of evolution, and has found that the evolutionary trajectory of a genome may be influenced by its evolutionary history, rather than determined by numerous factors and historical accidents.

A new analysis of fossils believed to be juveniles of T. rex now shows they were adults of a small tyrannosaur, with narrower jaws, longer legs, and bigger arms than T. rex. The species, Nanotyrannus lancensis, was first named decades ago but later reinterpreted as a young T. rex. The new study shows Nanotyrannus was a smaller, longer-armed relative of T. rex, with a narrower snout.
