Why should such regeneration be unique to the lower orders of life? To the theosophist, ... In the lower forms, however, the organic memory of the astral matrix pervades in latency the entire form, as must be the case if a small piece of a worm can reconstruct the complicated system of tissues and organs of its species.

Animals can teach us many things. Earthworm teaches about regeneration. ... Earthworm teaches regeneration. She turns the soil by bringing organic matter from the surface and mixing it with the soil below. Without Earthworm's efforts, crops would not grow as well. By Her actions, Earthworm turns "lemons into lemonade." Just...

Earlier this year, they got their first clues when they individually turned off 1,065 of the worm's genes, and found 240 that were involved in some aspect of regeneration. Importantly, S nchez Alvarado noted, 85 percent of these genes are found in the genomes of other organisms, including humans.
