The conclusions the scientists drew from their research were very similar to those that the average TV viewer might have drawn ---depending on snow conditions, penguins choose the method of movement that uses least energy,but tobogganing wears out their feathers,so they need to care for their feathers more often. I have no doubt that the scientists went through a great deal of soul-searching before they killed the penguin.Their work provided hard scientific proof for hypotheses about the way these flightless birds move in the Antarctic environment.It was good science,conducted on our behalf in the best traditions of the discipline for a sound motive--- the advancement of human knowledge---but it makes me feel uneasy.
