Predators drive the evolution of multicellularity

Discussions about the evolution of multicellularity tend to focus on animals and plants, but there have actually been at least 25 independent origins of multicellularity in the history of life on this planet, including fungi, slime molds, several groups of algae, cyanobacteria and myxobacteria. So... click to read more

From a fossil to a robot…and all the steps in between

Being almost 300 million years old, the extinct Orobates pabsti did not know that at some point in the future, engineers and biologists would have reconstructed its fossilized bones into a robot to study how it used to walk and thus, learn more things about... click to read more

A message in a bottle dating 250 million years ago

The phenomenon of plant groups originating in the tropics was observed by botanist George Ledyard Stebbins in 1973. He hypothesized that ecosystems in equatorial regions serve as "evolutionary cradles" that spawn new lineages at higher rates compared to ecosystems at higher latitudes. Especially those demanding... click to read more

Back off predators!! Herbivorous dinosaur with spiny neck

Sauropod dinosaurs, large herbivores with long neck and tail, include the largest terrestrial animals that ever inhabited the Earth such the giant titanosaur Patagotitan, or the colossal diplodocid Diplodocus. However, some groups of sauropods were not necessarily characterized by their size but by other anatomical... click to read more
