Félix Le Dantec

He obtained his Bachelor of Science degree at the École Normale Supérieure in Paris, where he later worked as an associate-trainer in the laboratory of Louis Pasteur.

Later, he returned to Paris (1896), where he worked in the laboratory of Alfred Giard at the École Normale Superieure and taught classes in embryology at the Sorbonne.

Here he engaged in long discussions with a priest on the subjects of religion and atheism, publishing the book Le conflit (1901) as a result.

His book Lamarckiens et Darwiniens was reviewed in the Nature journal as "a well-intended, but scarcely adequate, endeavour to reconcile the Darwinian with the Lamarckian conception of evolution.

"[4] He rejected the ideas of August Weismann and proposed his own biochemical theory of heredity which allowed for the inheritance of acquired characters.
