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.

Plants Combine Color and Fragrance to Procure Pollinators

ho knew that it’s possible to predict the fragrance of a flower by looking at its color? This is true for many of the 41 insect-pollinated plant species growing in a Phrygana scrubland habitat on the Greek island of Lesbos. An international research team published their findings Sept. 4 in Nature Ecology & Evolution.

Fruit Flies May Help Understand How Some Species Eat Poison

Out of hundreds of species of fruit flies, a handful can eat toxic mushrooms, and understanding why and how they pull this off could answer broader questions about evolution and adaptation.

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.

The Evolutionary Origin of the Gut

Technau_Gastrula-und-Keimblattschema-web.jpg

How did the gut, the skin and musculature evolve? This question concerns scientists for more than a century. Through the investigation of the embryonic development of sea anemones, a very old animal lineage, researchers from the University of Vienna have now come to conclusions which challenge the 150 year-old hypothesis of the homology (common evolutionary origin) of the germ layers that form all later organs and tissues.
