'Scientists are still working to classify this diversity and understand how it got here, says Selden, who coauthored a review on spider web evolution in the Annual Review of Ecology, Evolution, and Systematics. '
'Orb weavers, sometimes classified along with their descendants into a grouping called Orbiculariae, comprise about a quarter of the more than 45,000 known spider species. '
'This divergence in strand type has been a sticking point for scientists studying spider evolution, spinning out a long debate over how many times the orb web evolved. '
'Though web strands may be very different, the building behaviors are remarkably similar, says Jason Bond, an arachnologist at the University of California, Davis. '
'Their webs typically feature the classic concentric circle and spoke-like strands that radiate from a hub. '
