Forests of Unfamiliar Trees
Most of the towering trees in Carboniferous swamps were ferns, horsetails, or lycopsids, three very distinct groups. All needed ample water to reproduce, and they thrived in the human, tropical landscapes. Another group, see plants, could grow in dry places too, giving them an advantage.
Today, the scene has changed entirely. More than 80% of all plants belong to the flower-producing group of seed plants -- angiosperms, which evolved about 200 million years after the Carboniferous. |
