Flowering plants survived Earth’s worst disasters, including the asteroid strike that ended the dinosaurs, while many others ...

Get ready for a biology lesson. Certain plants have extra sets of chromosomes. And it turns out, it's a useful trait for a ...

Unlike humans, many plants have more than two sets of chromosomes. This trait may help them adapt to environmental upheaval, such as climate change.

When an asteroid as big as Mount Everest struck Earth 66 million years ago, it wiped out all non-avian dinosaurs and roughly ...

Many flowering plants have duplicated genomes, which could have helped them evolve to deal with extreme stress in times of ...

Researchers at Tulane University School of Medicine have discovered that if animal cells gain an extra set of chromosomes, a condition known as polyploidy, they activate a stress signaling pathway ...

Polyploidy has repeatedly driven plant diversification, adaptation, and innovation across evolutionary history. But while allopolyploidy has been widely studied, autopolyploidy—genome doubling within ...

Polyploidy, or whole-genome doubling, is one of evolution's most powerful forces in plants, yet its real-world consequences in natural populations remain poorly understood. This study uncovers a rare ...

“Our work highlights the need to study polyploidy and senescence in concert to understand their roles in aging, cancer, and therapeutic resistance.” “Our work highlights the need to study polyploidy ...

A new editorial was published in Volume 18 of Aging-US on February 8, 2026, titled "Polyploidy-induced senescence: Linking development, differentiation, repair, and (possibly) cancer?" In this ...

Scientists have developed a theoretical model that uncovers the dual role of polyploidy -- organisms carrying extra genome copies -- in evolution. Their findings reveal that polyploidy can stabilize ...
