On July 7, BBC News reported the rare discovery of a fossilized sea worm, classified as a hemichordate, a sophisticated invertebrate. Evolutionists are excited because this find supposedly provides insight into early evolution. And some evolutionists even see this worm—called Oesia—as a half-billion-year-old ancestor of man.¹

Hemichordates (Stomochordata) —the acorn worms inhabiting ocean sediments today—are anything but simple. They are designed with a net-like nerve plexus containing giant nerve cells, pharyngeal gill slits, glomerulus, longitudinal and circular muscle, and unique embryonic development.

But what do scientists know for sure regarding this new supposedly ancient fossil? Clearly, like its modern version, it's quite a complex creature. The article states Oesia "had U-shaped gills running down most of the length of its body, to enable filter feeding." The fossil showed the sea worm lived inside a sophisticated tube-like structure that served as a protective house. But to say this worm is our ancestor is a wholly unwarranted extrapolation.

Contrary to what the BBC article states, this half-billion-year-old fossil does not give scientists any "new insights into how early creatures evolved." It's merely a sea-worm fossil much like sea worms alive today. Indeed, in 2013 three evolutionists said, "Hemichordate [evolution] has long remained problematic."² British paleontologist Michael Benton stated, "The [evolutionary history] of hemichordates is actively debated."³ and six evolutionists said, "Hemichordate [evolutionary history] has long been puzzling."⁴

The amount of extrapolation needed to jump from sea worm to human is absolutely incredible. Evolutionists are simply speculating from something known to something unknown using conjecture and lots of imagination, rather than relying on an empirical process.

The fact that no undisputed transitional fossils exist doesn't seem to thwart evolutionary extrapolation nor wild claims, like we see in this story, of an ancestral connection between sea worms and humans. There must be a better scientific explanation.

Creation scientists view this Oesia fossil as an ocean bottom-dwelling sea worm buried suddenly during the first stage of the Genesis Flood.
