  • at least 16,000 hexagonally packed ommatidial lenses (in a single eye)
  • ...9 more annotations...
  • origin of compound eyes deeper down the arthropod stem lineage
  • evolved before such features as a hardened exoskeleton
  • processing of visual information would have required
  • sophisticated nektonic predators with acute vision
  • brain to be of comparable complexity to
  • modern) arthropods
  • within Cambrian communities would have placed considerable selective pressures on prey that would have influenced the ‘arms race’ that began during this important phase in early animal evolution
