In genetics, sizes often come with surprises. One tiny fern, Tmesipteris oblanceolata, also known as the Fork Fern, proved this phrase true, taking the scientific community by storm when it broke the record for the largest known genome. Researchers reported this discovery on May 31, 2024, stating that the plant, which is small enough to fit in the palm of your hand, harbors a full set of genetic instructions over 50 times the size of the human genome.
