Last year I blogged about the surprising discovery that mosses released after 400 years of frozen glacial ensquashment had managed to survive and sprout new growth, a finding that radically altered our ideas about regrowth during the retreat of ice ages. Now, a new study in Current Biology pushes that back at least a millennium [...]

In most land plants, including conifers and flowering [...]
