Does Chen's work pose a problem for ToE?

This topic was promoted from Message 19.As indicated in Message 21 of that thread, the discussion here is to be restricted to Chen's work, and the problems it might pose for ToE. In particular, other issues such as Haeckel, pakicetus, pepper moths, are off-topic for this thread.

Yes, that is implicitly included in what can be discussed. This is mentioned in the OP, and can be part of the discussion. But it should not dominate the discussion. The emphasis should be on the evidence, rather than on the opinions some have of this evidence. If Chinese scientists think there is a problem then they presumably have reasons, based on evidence, for thinking so. The discussion should emphasize the reasons, not the opinions.
