First one-celled organisms. A new study suggests the first plants to make this evolutionary leap appeared much earlier than we thought. The first land plants appeared. D. Reptiles appeared on Earth for the first time. Plant structures specialized for photosynthesis are called: Leaves. They aided animals in the colonization of land. Many of these creatures have been found in Silurian period rock layers, usually in association with fossils of the oldest-known vascular land plants. Thus, land plant spores must be distinguished from algal structures in the fossil record in order to identify the earliest land plants. These changes to . Earth is the planet of the plants—and it all can be traced back . Also the first land plants evolved. First vascular plants (plants with water-conducting tissue as compared with non-vascular plants like mosses) appear on land (Cooksonia is the first known).

All life started in the ocean, and like animals, plants had to move to land. The first land snails and insects with wings appeared (i.e., dragonflies and mayflies), and some of these had wingspans of more than three feet! Earth and Life, International Year of Planet . The new forests, dominated by the first trees, created a new biosphere and altered global carbon cycling. Cyanobacteria, bacteria that can photosynthesize, were the first photosynthetic organisms to move to land. According to researchers studying lungfish—a living model for hearing in our ancient ancestors—the first terrestrial creatures may have used their lungs to help them detect sounds. The Silurian is the first period with fossils of extensive non-microscopic life on land. (i) First animals were invertebrates. They absorbed near-infrared rather than visible light and produced sulfur or sulfate compounds . These studies are also improving our understanding of how the plant family first evolved. Some of these 'tools' evolved in early land plants and today are found in both tiny mosses and giant trees which form complex forest ecosystems.

They have a sterile jacket of cells around their gametes. These plants transformed Earth's environments, creating extensive marshlands. With this important evolutionary innovation, vertebrates no longer had to find water in which to lay their eggs. The first larger land animals to wander onto land were probably arthropods, such as scorpions and spiders. Prokaryotes are the organisms classified as Bacteria and Archaea, and are the most successful & abundant organisms on Earth. However, the exact timing of their origin remains a controversial topic.
