text: If all four groups obtained their plastid in the same symbiogenetic event from the same red alga (37), the cryptomonad nucleomorph would have originated more than 500 million years ago, not long after the symbiotic origin of chloroplasts, dated at about 600 million years ago by comparing the divergence times of these groups on molecular trees with the fossil record (3); even if the cryptomonads obtained their plastids separately (1), their phyletic depth on molecular trees (10) implies an age of over 200 million years.
