Oldest Known Flowering Plants Identified By Genes By William J.
Cromie Gazette Staff It’s a nondescript shrub with small, unimpressive flowers, and it’s found in only one place in the world – New Caledonia, a minor tropical island in a remote corner of the southwest Pacific. But it has suddenly catapulted to botanical eminence as a key piece in the puzzle of the origins of flowering plants. Called Amborella, the plant is the one remaining species of a lineage that first appeared on Earth more than 140 million years ago, while dinosaurs still ruled the planet. Mathews and Donoghue’s analysis revealed that another early branch includes Austrobaileya, a group represented by one species found only in Australia, and by the more common star anise, which boasts bright red, saucer-shaped flowers. Tracing flowering plants back so close to their roots ranks as one of the major botanical discoveries of this century. Copyright 1999 President and Fellows of Harvard College.

The bacteria that changed the world - May, 2017 The make-up of Earth's atmosphere, once the domain of Earth science textbooks, has become an increasingly "hot" news topic in recent decades, as we struggle to curb global warming by limiting the carbon dioxide that human activity produces.
While the changes that humanity has wrought on the planet are dramatic, this isn’t the first time that one species has changed Earth’s atmosphere. Three billion years ago, there was no free oxygen in the atmosphere at all. Life was anaerobic, meaning that it did not need oxygen to live and grow. That all changed due to the evolution of Cyanobacteria, a group of single-celled, blue-green bacteria. Plant Biology - CliffsNotes. 15 House Plants You Can Use As Air Purifiers.

Perhaps eventually you may drift ashore on the coral sand beaches of a remote tropical island or distant continent. This is precisely what happens to countless thousands of tropical drift seeds and fruits, a remarkable flotilla of flowering plants that travel the oceans of the world. The following map shows the path of some drift seeds and fruits in the world's oceans: Seeds provide the vital genetic link and primary dispersal agent between successive generations of plants. They are produced and packaged in botanical structures called fruits, and come in an endless variety of shapes and sizes. The tropical islands of Indonesia, Polynesia and the Caribbean probably have the greatest variety of drift seeds.
