Dino-Killing Asteroid's Impact on Bird Evolution

Liliput_Timeline_final.jpeg

Human activities could change the pace of evolution, similar to what occurred 66 million years ago when a giant asteroid wiped out the dinosaurs, leaving modern birds as their only descendants. That's one conclusion drawn by the authors of a new study published in Systematic Biology.

Big Herbivorous Dinosaurs Ate Crustaceans as Side Dish

Some big plant-eating dinosaurs roaming present-day Utah some 75 million years ago were slurping up crustaceans on the side, a behavior that may have been tied to reproductive activities, says a new University of Colorado Boulder study.

3-D Analysis of Dog Fossils Sheds Light on Domestication Debate

In an effort to settle the debate about the origin of dog domestication, a technique that uses 3-D scans of fossils is helping researchers determine the difference between dogs and wolves.

Genomic Recycling: Ancestral Genes Take On New Roles

Dr. Igor Ulitsky has found that ancient genes that lost their ability to make proteins were “recycled,” surviving across millennia – and species – by evolving to produce a type of RNA that regulates major biological processes. His findings could lead to treatments for a number of genetic diseases.

Bite Force Research Reveals Dinosaur-Eating Frog

Scientists say that a large, now extinct, frog called Beelzebufo that lived about 68 million years ago in Madagascar would have been capable of eating small dinosaurs.

Missouri S&T Geologist Leads $2.1M National Science Foundation Research Effort to Study Earth’s Greatest Mass Extinction

Missouri S&T geologist Dr. Wan Yang has devoted his academic career to unlocking the mysteries of thePermian mass extinction more than 250 million years ago. That geological odyssey now finds him leading an 11-institution consortium that’s been collectively awarded a $2.1 million National Science Foundation research grant.

When Ancient Fossil DNA Isn’t Available, Ancient Glycans May Help Trace Human Evolution

allia_bay_excavation.jpg

Researchers at University of California San Diego School of Medicine and collaborators discovered a new kind of glycan (sugar chain) that survives even in a 4 million-year-old animal fossil from Kenya, under conditions where ancient DNA does not. While ancient hominin fossils are not yet available for glycan analysis, this proof-of-concept study, published September 11 in Proceedings of the National Academy of Sciences, sets the stage for unprecedented explorations of human origins and diet.
