What you’ll learn

  1. A mammal built for a colonyExplain why naked mole-rats are called eusocial mammals and how colony labor is divided.A mammal becomes insect-like through cooperative care and reproductive division of labor.
  2. The burrow changes the rulesConnect the naked mole-rat's body and behavior to the climate and architecture of its burrow.The tunnel is a shared climate and workplace that rewards huddling, digging, and cooperation.
  3. When oxygen disappearsDescribe how naked mole-rats tolerate low oxygen and high carbon dioxide underground.They lower demand, tolerate unusual air, and switch fuels when oxygen becomes scarce.
  4. Strange defenses and long livesEvaluate the evidence for unusual pain resistance, cancer resistance, and longevity.The animal offers specific biological clues, not a pile of unrestricted superpowers.
  5. How an insect-like mammal makes senseSynthesize ecology, social behavior, anatomy, and physiology into an evolutionary explanation.The naked mole-rat makes sense as a linked set of solutions to underground problems.

Questions this course answers

Why can a naked mole-rat colony resemble an insect society?

Naked mole-rats are mammals, but they show cooperative care and a strong reproductive division of labor.

Put the low-oxygen response in order.

The animal lowers demand and changes fuel while oxygen is scarce, then resumes normal activity when air returns.

Match each trait to its role.

Each trait fits a different problem in the animal's underground life.

Why is the insect comparison useful but incomplete?

An analogy highlights a shared social pattern without making the animals identical.

What helps a naked mole-rat tolerate a poorly ventilated burrow?

Reduced metabolism, tissue tolerance, and a fructose-linked anaerobic pathway help during oxygen shortage.
