You Embody What Your Ancestors Experienced 14 Generations Ago

Researchers have discovered that environmental genetic changes (epigenetics) can be passed down for an incredible 14 generations in an animal – the largest span ever observed in a living organism.

A team led by scientists from the European Molecular Biology Organisation (EMBO) in Spain took genetically engineered nematode roundworms called C. elegans that carry a transgene for a fluorescent protein. Which when activated, this gene made the worms glow bright under the ultraviolet light.

Then, they changed the temperature of their containers. Keeping the nematodes at (68° F), they measured low activity of the transgene – which as a result the worms hardly glowed at all.

Researchers then changed the control in the experiment moving the worms to a warmer climate of 77° F, they suddenly lit up like Christmas trees, which meant the fluorescence gene had become less dormant.

The scientist finally moved the worms back to cooler temperatures to see what would happen to the activity of the fluorescence gene.
