There are species whose entire genomes get duplicated and stuffed into every one of their cells.
It can ultimately impact survival, but it's pretty common today, especially in plants.
Researchers scoured the DNA of several hundred plants for evidence of genome duplication events that occurred long ago and looked to see when they happened.
In particular, says Ghent University plant biologist Yves Vandeper, they clustered during periods of turmoil over the last 150 million years, times of dramatic cooling or warming or widespread extinction.
Genome duplication appears to allow plants to survive extreme environmental stress.

The standardized process of evaluating cacao took years to develop.
It involves roasting the beans, separating out the shells, and then running the nibs through a mill.
Sugar and cocoa butter are added before pouring the resulting chocolate into molds.
Julien Simonis helped develop the process for the Cacao of Excellence program, created by a non-profit in Rome.
Which helps persuade consumers to pay for higher quality chocolate, thereby benefiting farmers, many of whom struggle economically.
