Worms can live as long as four years. When worms die in the bin, their bodies decompose and are recycled by other worms, along with the food scraps.
Can worms come back to life?
MOSCOW: A sample of microscopic worms that were suspended in a deep freeze in Siberia for 42,000 years have come back to life after being defrosted, scientists say. After defrosting the worms, researchers saw them moving and eating, making this the first evidence of “natural cryopreservation” of multicellular animals.
How old is the oldest nematode?
“The oldest known nematodes are from about 400 million years ago, but I believe they probably date back to around 1 billion years,” Poinar said. “That would mean they were one of the very oldest of all life forms, coming along before almost all other animals and just after bacteria, protozoa and fungi.
Will frozen worms come back to life?

Did humans evolve from nematodes?
According to accepted evolutionary theory, nematodes and humans split more than 600 million years ago. Of the 5000 best known human genes, three fourths have close analogues in the nematode. This implies that these roughly 3700 genes were represented in the most recent common ancestor of humans and nematodes.
