It eats detritus and plays a critical role in the breakdown and transport of carbon dioxid...

Proof of Dark Matter in the Universe In the University of Arizona, scientists discovered that dark matter exists.

Fossils of embryos The embryo fossils have been found dating back more than 500 million years ago. These fossils have been found in China and Siberia. They are preserved in the rocks.

Scientists of the University of Bristol have found the fossil to be of Markeulia, a worm like animal. The sci...
