“We carried out a lot of analyses to work out whether or not Sollasina was extra intently associated to sea cucumbers or sea urchins,” Dr. Thompson mentioned within the launch. “To our shock, the outcomes counsel it was an historic sea cucumber. This helps us perceive the adjustments that occurred through the early evolution of the group, which finally gave rise to the slug-like types we see at the moment.”
