What is a Lemming?
A lemming is a small rodent that belongs to the subfamily Arvicolinae in the family Cricetidae. Lemmings are known for their mass migrations and mythological associations with jumping off cliffs en masse.
Characteristics of Lemmings
- Small, furry rodents
- Found in the Arctic tundra and boreal forests
- Known for their cyclic population explosions and migrations
Common Misconceptions
Contrary to popular belief, lemmings do not purposely jump off cliffs. The myth likely originated from the Disney documentary “White Wilderness,” where filmmakers staged lemmings jumping off a cliff to create a dramatic scene.
Case Studies
In 1958, scientists conducted an experiment to study lemming behavior by placing them on a turntable, simulating a cliff edge. The lemmings did not jump off but instead turned around and went in the opposite direction.
Statistics
According to research, lemmings exhibit cyclic population explosions every 3-4 years, followed by mass migrations. These migrations help prevent overgrazing and maintain ecological balance in their habitat.
