Shaking dinosaur hips and messing with their heads

by Piter Boll in Earthling Nature

by Piter Kehoma Boll This week brought astonishing news regarding the phylogeny of dinosaurus, as you perhaps have heard or read. New anatomical evidences have completely rebuilt the basis of the dinosaur family tree and I’m here to explain a … Continue reading →... Read more »

Friday Fellow: Pliable Brachionus

by Piter Boll in Earthling Nature

by Piter Kehoma Boll Charles Darwin had already noticed that small animals, such as those found in zooplankton, are widely distributed around the world, even those that are found in small ponds of freshwater. This seemed to go against the … Continue reading →... Read more »

New paper “Clustering Genes of Common Evolutionary History”

by Christophe Dessimoz in Open Reading Frame

This is how molecular systematics has worked since the sixties: you take some identifiable feature (e.g. a gene or a protein) common to a group of species and take some measurements of it (e.g. sequencing the DNA). By comparing the results of these measurements you can estimate the evolutionary tree that links the species. Shortly after people started doing this they realised there was a problem: when analyses are based different genes they often estimate different —incongruent — evo........ Read more »

How a new species of Lyme disease bacteria was discovered

by Microbe Fan in Spirochetes Unwound

A new agent of the tick-borne illness known as Lyme disease has emerged in the upper Midwest.  The bacterium is genetically related to Borrelia burgdorferi, until now believed to be the only cause of Lyme disease in the United States.  The name proposed for the bacterium is Borrelia mayonii because the work was conducted at the Mayo Clinic.  B. mayonii has not been detected in patients outside of the Midwest (so far).  The findings are described in The Lancet Infectious Disea........
