Those headlines look familar.
What clues did planarians (flatworms?!) give to early migrations?
Edit to add:
It seems to be a real article:

Corona Daily Independent (Newspaper) - March 1, 1956, Corona, California Planarians Give New Clues to Early Migrations WASHINGTON—A wOrm, among earth's most primitive animals, may provide clues to ancient intercontinental migrations. It is one of four hitherto unknown species of freshwater planarians collected in Alaska by Dr. Roman Kenk, a foremost authority on these fantastic creatures. Some of these four species are quite Similar to planarians now found in Siberia. They are unlike any known elsewhere in North America. Their presence in Alaska, Dr. Kenk holds, provides additional evidence of the existence of an ice-age land bridge between A-sia and North America and of the fact that during the ice ages, when glaciers covered most of the northern half of this continent, most of Alaska was ice tree. Planarians, although familiar animals in biological laboratories, are very little known in nature. They are among the most fantastic of all animals, sometimes described as "gliding patches of slimy skin" without a body cavity, able to break up at will into scores of pieces each of which regenerates into a new worm. They overpower their prey by wrapping their slimy bodies around it. They predigest it outside the body by projecting the pharynx, a part of the alimentary tract and secreting soma digestive materiaL
