The fossilized nerve tissue dates back 508 million years and is included in
two microscopic fossils, each smaller than an aspirin pill. The Cambrian
insects could aid in understanding how spiders and scorpions evolved.
According to Nicholas Strausfeld, a regents professor in the Department of
Neuroscience at the University of Arizona who was not involved in the work,
it is still unclear where these fossils, both examples of the species
Mollisonia symmetrical, belong on the arthropod evolutionary tree.
