A paper published today (12 June 2026) in Current Biology is almost guaranteed to upset any creationists with the courage to read it and the ability to understand it. Written by an international team led by Associate Professor Paul Marek and Dr Luisa F. Vasquez-Valverde of Virginia Tech, it reports the completion of the first evolutionary history of all living millipede orders, including two rare groups whose DNA had never previously been included in a phylogenetic analysis.
Millipedes were amongst the earliest animals to colonise the land, arriving long before vertebrates had made the transition from water to land. According to the researchers, they beat vertebrates onto land by more than 80 million years. As detritivores, they helped to establish early terrestrial ecosystems by breaking down decaying organic matter and recycling nutrients, gradually helping to create soils in which later plant communities could develop.
For more than a century, biologists have known that two rare groups of millipedes — Siphoniulida and Siphonocryptida — existed, but without fresh specimens it was impossible to analyse their DNA and confirm where they belonged in the millipede family tree. One of the groups includes species barely a centimetre long that spend their entire lives underground; the other is known from only a few locations.
Members of the team therefore travelled to Los Tuxtlas, Mexico, and the Spanish Canary Islands to collect Siphoniulus neotropicus and Hirudicryptus canariensis, the two millipedes whose DNA had not previously been included in an evolutionary analysis. By sequencing DNA from these groups, comparing hundreds of genes across 82 millipede species, and combining those results with evidence from 29 fossils, the researchers were able to determine where the groups fit into millipede history and when their lineages emerged.
The result was especially interesting because one of the supposed “orders”, Siphonocryptida, appears not to be a separate order after all, but part of an existing lineage. The other, Siphoniulida, could finally be placed among its closest relatives on the millipede evolutionary timeline. The analysis also pushed the likely origin of millipedes back to nearly 460 million years ago — roughly 35 million years earlier than the oldest known millipede fossils.
This is bad news for creationists for at least three reasons:
- It shows these arthropods had their origin hundreds of millions of years before their mythical “Creation Week”.
- It shows a long history of descent from a common origin, just as the Theory of Evolution predicts.
- It shows the researchers were entirely dependent on evolutionary theory to frame the question, predict relationships, interpret the DNA and fossil evidence, and explain the results — with no hint that they found evolution inadequate and no need to invoke magic, special creation, or the long-promised “collapse of Darwinism” that creationists have been assuring their followers is imminent, and has been for more than half a century.
