What Animal Ages Faster Than Humans?

Published in Animal Biology 1 min read

Many animals age faster than humans. One example is the common house mouse, which has a lifespan of only about two years. This means that a one-year-old mouse is considered an adult, while a one-year-old human is still a child.

Here are some other examples of animals that age faster than humans:

  • Fruit flies: These insects have a lifespan of only a few weeks.
  • Guppies: These small fish can live for a few years, but they age much faster than humans.
  • Rats: These rodents have a lifespan of about two to three years.
  • Dogs: While dogs have a lifespan of about 10 to 15 years, they age much faster than humans. A one-year-old dog is considered to be about 15 years old in human years.

These are just a few examples of animals that age faster than humans. There are many other animals, both large and small, that have shorter lifespans and age more quickly than humans.
