Question

nincompoop · Answer

Either this is an example of a bad grammar or it is a trick question, because contrasting similarities is paradoxical.  

just a snapshot on a very complicated topic: 

They both believe in evolution- that is changes occur in species.  Lamarck's proposal for mechanism was that species evolve about its lifetime like the example of elongation of a giraffe's neck, while Darwin's natural selection is about gradual changes over time.  Darwin, thought that evolution does not take place at an individual/species level, but on population.
