New tools filter noise from evolution data
While rates of evolution have appeared to accelerate over short time periods, new analysis suggests that statistical noise is affecting the data patterns. A professor at the University of Tennessee, Knoxville, and his colleague ...

Gene regulation study reports surprising results: Extensive regions of DNA belong to multiple gene switches
Some sequences in the genome cause genes to be switched on or off. Until now, each of these gene switches, or so-called enhancers, was thought to have its own place on the DNA. Different enhancers are therefore separated ...

'Genetic time machine' reveals complex chimpanzee cultures
In recent decades, scientists have clearly demonstrated that chimpanzees, like humans, pass on complex cultures such as tool use from generation to generation. But human culture has become vastly more sophisticated, from ...

Gene expression shifts help explain how a shrew changes brain size to match the seasons
New research shows how the Eurasian common shrew (Sorex araneus) changes its brain and bodily size throughout the year. The study, published online in eLife, reveals how changes in gene expression enable these small mammals ...

Dinosaur drumsticks, X-ray videos and 3D models shed light on the evolution of bird motion
Wings may be the obvious choice when studying the connection between dinosaurs and birds, but a pair of Yale paleontologists prefer drumsticks. That part of the leg, they say, is where fibular reduction among some dinosaurs ...

Superior photosynthesis abilities of some plants could hold key to climate-resilient crops
More than 3 billion years ago, on an Earth entirely covered with water, photosynthesis first evolved in ancient bacteria. In the following millions of years, those bacteria evolved into plants, optimizing themselves along ...

Blind cavefish study provides new insights into the evolution of neurons in vertebrate brains
Assumptions that may seem self-evident are not always accurate when it comes to the evolution of vertebrate brains. Researchers at the University of Bayreuth have now demonstrated this by examining the largest neuron in the ...

Seemingly 'broken' genes in coronaviruses may be essential for viral survival
Viruses are lean, mean, infection machines. Their genomes are tiny, limited to a handful of absolutely essential genes, and they shed extra genomic deadweight extremely fast... usually.
