Abstract

Drs Oakley and Dodge reply: In regard to Dr R. E. Lee's correspondence, our letter to Nature1 was not intended to be particularly critical of Dr Lee's previous article on endosymbiosis and the evolution of the algae2. In fact Dr Lee's theory was only mentioned very briefly. Nevertheless we should like to respond to his comments. Of course when we stated that “the Cryptophyceae were thought to be ancestral and closely related to the Cyanophyceae”, there was no intentional implication that the Cryptophyceae were ancestral to the Cyanophyceae but rather that they were ancestral algae. Since Dr Lee's scheme regards them as ancestral to every group of algae other than the Cyanophyceae we feel that it is fair to regard them as ancestral. Although Dr Lee does not state explicitly that the Cryptophyceae are closely related to the Cyanophyceae, his chart (Fig. 1) giving phylogenetic relationships places two groups of cryptophytes, the colourless cryptophytes and those with cyanelles, closer to the Cyanophyceae than any other groups of algae. We do not feel, therefore, that our statement was unfair.
