Sheldrake's morphic resonance hypothesis posits that "memory is inherent in nature"[3][8] and that "natural systems, such as termite colonies, or pigeons, or orchid plants, or insulin molecules, inherit a collective memory from all previous things of their kind".[8] Sheldrake proposes that it is also responsible for "telepathy-type interconnections between organisms".[9] His advocacy of the idea encompasses paranormal subjects such as precognition, telepathy and the psychic staring effect[10][11] as well as unconventional explanations of standard subjects in biology such as development, inheritance, and memory.[12]
