Title: What adaptations may have enabled plants to withstand these disasters better than animals? Post by: Ashmo on Mar 8, 2011 The history of life has been punctuated by several mass extinctions. For example, the impact of a meteorite may have wiped out most of the dinosaurs and many forms of marine life at the end of the Cretaceous period. Fossils indicate that plants were less severely affected by this and other mass extinctions. What adaptations may have enabled plants to withstand these disasters better than animals? Why are seed plants more successful than the so-called “lower plants”? Title: What adaptations may have enabled plants to withstand these disasters better than animals?

But seeds, as the temperatures are low, remain resting in the earth until the circumstances improve. (In many cases for years and years) And so the species survives.Title: What adaptations may have enabled plants to withstand these disasters better than animals?
