by Misha Guptafigures by Xiaomeng Han For close to two centuries, humans have been studying the biological past using fossil records. In recent history, we have added the ability to reconstruct the sequence of our DNA to our arsenal. Furthermore, phylogenetic trees (structures that define the evolutionary relationships in the line of descent from a common ancestor) have been created for all manners of organisms, … Continue reading Viral Fossil Records: A Look into the Past! (and the Future?)￼
Evidence of a respiratory infection was discovered in a 150 million year old dinosaur providing further understanding of prehistoric disease acquisition Continue reading Even Dinosaurs Get Sick: Discovery of the Oldest Lung Infection in a Dinosaur
A new study comparing Velociraptors and their modern counterparts, Komodo dragons and crocodiles, concludes that raptors were unlikely to be social, pack-hunters, in contradiction to their popularized portrayal in the ‘Jurassic Park’ movies. Continue reading ‘Jurassic Park’ was wrong: Study suggests raptors didn’t hunt in packs
Researchers at UC Riverside have discovered the oldest ancestor of almost all animals, including humans. This worm fills in a long-missing gap of the evolutionary biology puzzle. Continue reading Researchers Discover Oldest Ancestor of Almost Every Animal
Tyrannosaurus Rex, Triceratops, Saber-toothed Tiger…as kids, we probably imagined these creatures using a variety of crayon colors. But what if we could figure out what color these creatures actually were? A scientific technique developed by Roy Wogelius involving the Interdisciplinary Centre for Ancient Life at the University of Manchester may paint the ancient world in its truest form. Paleontologists use information contained in fossils to try … Continue reading So what color was that dinosaur, actually?
Dogs are “man’s best friend,” but how long have they been our four-legged companions? A recent study suggests that dogs and humans may have formed close relationships as early as 6,000 years ago — a relationship that involved humans feeding the dogs, but ended with the dogs being sacrificed. Canine remains from this era have been uncovered before, but this study adds 26 more specimens … Continue reading Dogs and humans were buried together in 6,000-year-old graves
The frozen desert of Antarctica is not exactly a place you would want to call home. But under its surface lies an unexplored, watery world of subglacial lakes and rivers stretching for millions of square miles, the ice above exerting enough pressure to keep them from freezing. But when scientists found a diverse bacterial haven in the secluded lakes, they were mystified: What other organisms … Continue reading Breaking the ice: Scientists find signs of ancient life in submerged Antarctic lake
How a 300-million-year-old mystery fossil is reshaping our understanding of what it means to be a vertebrate. by Kelsey Lucas figures by Brad Wierbowski Through murky water you spot it – a creature with a cylindrical body, tapering at each end like a football. At one end, a spade-like tail fin fans out as it slowly beats back and forth. At the other end, a … Continue reading Enigmatic Tully Monster Finds a Home on the Tree of Life
