A study has found that the reason why the evolution of the first animals to appear on Earth was delayed for over 10 million ...

A recent study by Ruibao Li and Jennah Dharamshi published in Nature may help us understand the beginnings of animal ...

Animals able to change behaviors but slow to evolve might fare better than previously thought amid climate change. In response to a warmer climate, ground squirrels and marmots in California are ...

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 ...

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 ...

Phylogenomic analysis harnesses genome-scale data sets to reconstruct the deep branches of the animal tree of life, resolving longstanding debates about the relationships among major lineages such as ...

Tracks left by some of the earliest complex animals are giving new insights into how they experienced the world. New research ...

A huge and beautifully preserved suite of fossils discovered in China has cast doubt on the idea that complex life flourished dramatically during a rapid burst of evolution known as the Cambrian ...
