Scientists identify rare evolutionary intermediates to understand the origin of eukaryotes
Took me a while to work out what this is really about, but it appears to be about ribosomal proteins in archaea.
Half-a-billion-year-old tiny predator unveils the rise of scorpions and spiders
Two palaeontologists working on the world-renowned Burgess Shale have revealed a new species, called Mollisonia plenovenatrix, which is presented as the oldest chelicerate. This discovery places the origin of this vast group of animals--of over 115,000 species, including horseshoe crabs, scorpions and spiders--to a time more than 500 million years ago.

Ground-breaking method to reconstruct the evolution of all species
Researchers identified an almost complete set of proteins, a proteome, in the dental enamel of the now-extinct rhino and the resulting genetic information is one million years older than the oldest DNA sequenced from a 700,000-year-old horse.
Long before other fish, ancient sharks found an alternative way to feed
