Fruit Flies May Help Understand How Some Species Eat Poison

1708072_MW_0009_fly_story.jpg

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

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

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.

Birds Choose Mates with Ornamental Traits

A recurring theme in nature documentaries is that of choosy females selecting brightly colored males. A new study shows that, in monogamous mating systems, male birds may select their lifelong mates in much the same way.

Was the Primordial Soup a Hearty Pre-Protein Stew?

How proteins evolved billions of years ago, when Earth was devoid of life, has stumped many a scientist. A little do-si-do between amino acids and their chemical lookalikes may have done the trick. Evolutionary chemists tried it, and got results by the boatload.

Apes’ Abilities Misunderstood by Decades of Poor Science

New research argues that what we think we know about apes’ social intelligence is based on wishful thinking and flawed science.

New Computational Model of Chemical Building Blocks May Help Explain the Origins of Life
