I can't really buy the transitory species thing, but I would like to talk about this one:
Was Mr. deVries certain that he planted only plants without the variant? What kind of controls were in place? Was the new species viable? Can it still be found today? Has a similar experiment ever been tried again? (I realize this one is a little over the edge, but in order to be science it must be repeatable, otherwise you are just asking me to believe this man deVries who I have no experience with)
While studying the genetics of the evening primrose, Oenothera lamarckiana, de Vries (1905) found an unusual variant among his plants. O. lamarckiana has a chromosome number of 2N = 14. The variant had a chromosome number of 2N = 28. He found that he was unable to breed this variant with O. lamarckiana. He named this new species O. gigas.
