CHICAGO, Illinois (Reuters) -- The branches of Earth's oldest tree probably waved in the breeze like a modern palm, scientists said on Wednesday, based on two intact tree fossils that help explain the evolution of forests and their influence on climate.
The 385-million-year-old fossils, which scientists believe are evidence of Earth's earliest forest trees, put to rest speculation about fossilized tree stumps discovered more than a century ago in Gilboa, New York.
Scientists believe these early forests absorbed carbon dioxide, cooling the Earth's surface.
