A piece of preanimate biomatter was found on an asteroid in 2377 by The Doctor, who discussed the depths of the discovery to 7 of 9. When she explained that all she saw was an undeveloped nucleus contained in a cytoplasmic matrix, The Doctor added that buried deep within the nucleus were primitive strands of DNA – "the beginnings of life."
