Latest Xenoturbella Stories
The tiny worm the Xenoturbella bocki has caused a lot of controversy amongst scientists trying to decide if it truly was the ancestor of mankind. A new study from Sweden, however, indicates that the worm is indeed mankind's progenitor.
An international team of scientists including Albert Poustka from the Max Planck Institute for Molecular Genetics in Berlin has discovered that Xenoturbellida and the acoelomorph worms, both simple marine worms, are more closely related to complex organisms like humans and sea urchins than was previously assumed.
Evolution is not a steady march towards ever more sophisticated beings and therefore the search for the living "missing links" is pointless.
"Man is but a worm" was the title of a famous caricature of Darwin's ideas in Victorian England.
Two groups of lowly marine worms are related to complex species including vertebrates (such as humans) and starfish.
Researchers at the Sven LovÃ©n Centre for Marine Sciences at the University of Gothenburg have discovered a brand new species of bacterium found only in the Gullmarsfjord north of Gothenburg.
In the most computationally intensive phylogenetic analysis to date, an international research team led by Brown University has found the first evolutionary branching for bilateral animals.
Genetic analysis of an obscure, worm-like creature retrieved from the depths of the North Atlantic has led to the discovery of a new phylum, a rare event in an era when most organisms have already been grouped into major evolutionary categories.
