Lamarck saw spontaneous generation as being ongoing, with the simple organisms thus created being transmuted over time (by his mechanism) becoming more complex and closer to some notional idea of perfection.
However Lamarck did not count injury or mutilation as a true acquired characteristic, only those which were initiated by the animal's own needs were deemed to be passed on.
Charles Darwin praised Lamarck in the third edition of The Origin of Species for supporting the concept of evolution and bringing it to the attention of others.
