A team of researchers affiliated with several institutions in Australia has proposed that some neurological disorders might have their roots in evolutionary mistakes. In their paper published in the journal Nature Neuroscience, ...
Symptoms of illness are not inevitably tied to an underlying disease —rather, many organisms, including humans, adapt their symptom expression to suit their needs. That's the finding of Arizona State University's Leonid ...

Researchers have designed a method that can universally test for evolutionary adaption, or positive (Darwinian) selection, in any chosen set of genes, using re-sequencing data such as that generated by the 1000 Genomes Project. ...
