Mini pig (IMAGE)
Caption
Pigs resemble humans more than mice and rats do. But because pigs are more expensive to use as a model organism in research into new medicines, the small rodents are used more often. However, better knowledge about what makes pigs and humans similar could make pigs even more valuable in developing new medicines for humans. The photo shows a pig that has been bred to study atherosclerosis.
