It can be inferred that of the two laboratory environments mentioned in the passage, the one with oyster chips was designed to prove that the presence of oyster chips was not necessary for the develop- ment of a crusher claw. prove that the relative length of time that the lobsters were exposed to the oyster-chip environment had little impact on the development of a crusher claw eliminate the environment as a possible influence in the development of a crusher claw control on which side the crusher claw develops simulate the conditions that lobsters encounter in their natural environment!
