In the 19th century, the light-coloured peppered moth had pigmentation very similar to the lichens on
the tree barks on which it rested. Because they rested on these lichens, the moths were hard to see
and therefore protected from predatory birds. During the industrial revolution many parts of
England became covered with coal dust, soot and other dirt.

Use the following to answer the next two questions.
Birds such as thrushes prey on snails by cracking open shells on a stone. Broken
shells collected from around such a stone situated in rough grassland were
found to be pink and unbanded. However, most of the living snails in the area
were found to have yellow, banded shells.
27.
The best explanation for this finding is:
a.
b.
c.
d.
28.
the yellow, banded snails mimic a poisonous snail and were not selected
by the thrushes
the pink, unbanded snails are camouflaged and were not seen by the
students who collected data
the yellow, banded snails are camouflaged and have a selective
advantage, gradually becoming more common
the yellow, banded snails are most visible and were easily observed by
the students collecting data
In a grassland area which was heavily grazed, the populations of pink shell and
yellow shell snails were approximately equal. A reasonable explanation for this
would be:
a.
b.
c.
d.
shorter vegetation reduced the cover for the snails and both types were
equally conspicuous to predators
both varieties were equally difficult to see against the depleted
vegetation
reduced grassland has limited the food available to both varieties equally
both varieties were increased by the open spaces produced by the heavy
grazing.

statement below helps to explain this change, based on Lamarck’s reasoning?

Larger horses survived, smaller ones perished, thus leaving bigger horses
Larger horses produced more offspring than smaller horses, thus
changing the genetic make-up of each population.
