An article published in the journal “Science” describes the study of two incomplete skulls dated between 105,000 and 125,000 years discovered in the Henan province in eastern China. An international team examined the fragments found describing the mixed characteristics that put together those of various species of hominids. An intriguing hypothesis is that these are the mysterious Denisovans, of which very few bones were found. Unfortunately the attempt to recover DNA fragments failed.

An article published in the journal “Scientific Reports” describes the discovery of a primitive worm with jaws that are huge compared to its body’s size. Called Websteroprion armstrongi, it was studied by a team of researchers after a fossil specimen was discovered at the Royal Ontario Museum, where it was stored in the mid ’80s. It seems to belong to the class of polychaetes (Polychaeta), a marine relative of earthworms and leeches that lived about 400 million years ago.
