Which came first: The chicken or the dinosaur?

At first glance, a chicken and a dinosaur may seem as distantly related as any two species could be. For Hans Larsson, McGill associate professor of paleontology and biology and director of the Redpath Museum, the correlation between the two could not be clearer. In his presentation on Sept. 14, “Freaky Friday: Weird things I… Keep Reading

Say hello to the chickensaurus

Instead of building a time machine to travel back to prehistoric times, scientists might be able to engineer dinosaurs out of chickens to live in our own backyards. In a study published this past January in the Journal of Organic Evolution, researchers were able to genetically modify chicken embryo legs to resemble that of tetrapod… Keep Reading

All for one and one for all

The origin of life on Earth remains a heavily researched topic in evolutionary biology. Among the myriad of questions yet to be answered is how simple, single-celled organisms evolved to be complex and multicellular. While the mechanism for this phenomenon has been elucidated in plants and fungi, little is known about the evolution of multicellularity… Keep Reading

Research Briefs—Oct. 28, 2014

Physicists transport marbles with optical tractor beam The tractor beam—a long-distance invisible attraction beam—is a legendary staple in science fiction. In real life, moving objects using only light seems absurd, if not impossible. However, in a paper published in Nature Photonics, a team of Australian and American physicists successfully transferred glass marble ten centimetres using… Keep Reading

McGill researchers spotlight Polypterus fish

A team of researchers led by Dr. Hans Larsson from McGill University has made a key discovery in the process by which creatures evolved from aquatic to terrestrial animals. The study used the Polypterus fish as a means to investigate phenotypic evolutionary changes. Keep Reading
