Lamark formulated an evolution theory before Darwin did. He supposed 
that new species evolved out of existing species by means of little 
changes over time. He saw that animals were well adapted to their 
surroundings so he supposed that during their life organisms changed 
as a response to demands of the environment. His famous example is that 
of the giraffe that stretches its neck because it tries to reach higher leafs. 
Its children will already have a somewhat longer neck and they in their 
turn will stretch it too.
So Lamarckian evolution is a process whereby a quality, acquired during 
the life of an organism as a response to its situation is somehow preserved in 
the species for next generations. Mind you, This is the answer of a biologist 
interested in genetic programming not of a computer scientist.
