I've been fascinated by Sheldrake and his ideas since I ran across him in Wim Kayzer's book, A Glorious Accident, which I have mentioned before. Sheldrake expounds at length on the ideas in the article you found. I put a number of his thoughts in my book. Sheldrake believes in species consciousness and I do also. He thinks of memory as occurring in a brain like a radio receiver picking up past signals. He may well be right.
