From Joachim Barrande 19 June 1870
Summary
Encloses a copy of a letter he has written to a French geologist. In it he raises objections to evolutionary theory:
why are corals inadequately represented in the fossil record?
How can one explain the widespread appearance and then disappearance of groups like the trilobites?
If Mollusca and Articulata have a common ancestor, why are not ancient forms more akin than present ones?
