Mind or Consciousness is an illusion created by a specific cognitive architecture in order to simplify control. As such only those animals having that specific cognitive architecture are likely to be conscious.

The seeds of consciousness were probably laid at or about the time of the die off of the dinosaurs. Up until that point most vertebrates were aware but not conscious. However the requirements of the extinction event, forced new mutations, and one of these was the ability to keep blood warm, a capability called endothermic today. The endothermic species that emerged from the extinction event, also showed an increased flexibility in what niches they could fill, which might indicate the ability to become conscious. If so the adaptation that created consciousness is limited to the Birds and Mammals
