Ancient ecosystems organized much like our own

It was an Anomalocaris-eat-trilobite world, filled with species like nothing on today's Earth. But the ecology of Cambrian communities was remarkably modern, say researchers behind the first study to reconstruct detailed food webs for ancient ecosystems. Their paper, published this week in the open-access journal PLoS Biology, suggests that networks of feeding relationships among marine species that lived hundreds of millions of years ago are remarkably similar to those of today.
