She felt so happy in beautiful France, the fruitful land of genius, with the crater of freedom. But in her heart the sting remained that the bird, that every animal that could fly, was much better off than she. Even the fly could look about more in the world, far beyond the Dryad’...
The first “true” land plants were probably flat liverwort- like plants with little leaves only one cell layer thick. Again, these first land plants are remembered in the rocks only by their spores. Being able to withstand the physical stresses of drying and rehydration, the tough spore wall...
The terrestrial world is green now, but it did not start out that way. When plants first made the transition ashore more than 400 million years ago, the land was barren and desolate, inhospitable to life. From a plant’s evolutionary view point, however, it was also a land of opportunity...

The Egyptians were not far behind in developing writing, but we cannot follow the history of their writing in detail because they used a perishable writing material. In ancient times the banks of the Nile were lined with papyrus plants, and from the papyrus reeds the Egyptians made a form of...
The lake is about 400 meters below the sea level. The weather is hot there and the water is salty. Fish can not live in the salty water and plants cannot grow near it. People cannot swim well in the Dead Sea, but they can float in the water. You can often see people floating on...
Canarian dependence on domestic livestock across the archipelago and evidence of cultivation (at least at one time) on all its islands clearly fit this pattern, reinforced by the paucity of native land animals (birds, reptiles, mammals) and edible plants that could have substituted for these ...
When plants first made the transition ashore more than 400 million yearsago, the land was barren and desolate, in hospitable to life. From a plant’sevolutionary view point, however, it was also a land of opportunity, free ofcompetitors and predators and full of carbon dioxide and sunlight ...
