WFS News: Synthetic microorganisms and study of evolution

@ WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Scientists at Scripps Research and their collaborators have created microorganisms that may recapitulate key features of organisms thought to have lived billions of years ago, allowing them to explore questions about how life evolved from inanimate molecules to single-celled organisms to the complex, multicellular lifeforms we see […]

Mammal forerunner that reproduced like a reptile sheds light on brain evolution

Compared with the rest of the animal kingdom, mammals have the biggest brains and produce some of the smallest litters of offspring. A newly described fossil of an extinct mammal relative — and her 38 babies — is among the best evidence that a key development in the evolution of mammals was trading brood power […]

New Antarctic rift data has implications for volcanic evolution

New data revealing two tectonic plates fused to form a single Antarctic Plate 15 million years later than originally predicted and this extra motion has major implications for understanding of the tectono-volcanic activity surrounding the Pacific Ocean, from the Alpine mountains in New Zealand to the California geological setting, according to research from Ben-Gurion University […]

WFS News: Evolution of bipedalism in ancient dinosaur ancestors

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Paleontologists at the University of Alberta have developed a new theory to explain why the ancient ancestors of dinosaurs stopped moving about on all fours and rose up on just their two hind legs. Bipedalism in dinosaurs was inherited from ancient and much smaller proto-dinosaurs. The trick to […]

Fossil holds new insights into how fish evolved onto land

The fossil of an early snake-like animal — called Lethiscus stocki — has kept its evolutionary secrets for the last 340-million years. Now, an international team of researchers has revealed new insights into the ancient Scottish fossil that dramatically challenge our understanding of the early evolution of tetrapods, or four-limbed animals with backbones.

Whales only recently evolved into giants!!!

The blue whale, which uses baleen to filter its prey from ocean water and can reach lengths of over 100 feet, is the largest vertebrate animal that has ever lived. On the list of the planet’s most massive living creatures, the blue whale shares the top ranks with most other species of baleen whales alive […]
