A population of small mammals is moved to a colder environment. Scientists compare predictions from Darwin's theory and Lamarck's theory about thicker fur in later generations.
Which possible result would support Lamarck's theory rather than Darwin's theory?
The mammals grow thicker fur in the colder environment, but their offspring have ordinary fur when raised in warm conditions.
The mammals grow thicker fur during their lives, and their offspring are born with thicker fur even when raised in warm conditions.
Some mammals already have alleles for thicker fur and produce more offspring in the colder environment.
A mutation for thicker fur occurs before the move and becomes more common after several generations in the colder environment.
