The way you're asking the question, the answer would be: none. That's because individuals do not evolve adaptations over their life times in response to particular environmental conditions -- Lamarck thought evolution worked that way. Adaptations appear and get fixed in populations across generations (i.e., a mutation arises that is beneficial in that environment, conferring its possessor increased fitness, thereby spreading in the population in subsequent generations).
