A sweeping analysis of thousands of animal genomes suggests that chromosomes do not evolve randomly but instead follow a limited number of irreversible “evolutionary highways.” These one-way genetic ...

A completely new order of marine sponges has been found by researchers at the Museum of Evolution, Uppsala University. The sponge order, named Vilesida, produces substances that could be used in drug ...

By examining thousands of genomes along with fragments of ancient chromosomes, researchers uncovered the intricate journey of ...

Movement defines life across the animal kingdom. From a fish cutting through water to a bird taking flight, muscles power every action. For decades, scientists believed the machinery behind those ...

When the environment changes dramatically, animals from mollusks to crows can make big changes in their behavior that enable them to survive. For example, marmots and ground squirrels in California ...

New research suggests ancient feces helped fuel marine life during the Cambrian Explosion.

The study outlines a new scenario for understanding how genome regulation and chromatin organization influence the evolution of animal body plans. The conservation of genome regulatory elements over ...
