In evolutionary biology, convergent evolution is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar ...

The potential evolutionary link between hairs in mammals, feathers in birds and scales in reptiles has been debated for decades. Today, researchers demonstrate that all these skin appendages are ...

New 3D reconstructions of a key sensory organ in ctenophores reveal an unexpected structural and functional complexity. The findings suggest that an elementary brain may have already appeared in our ...

A new international study reveals the unexpected importance of acoustic communication in the evolution of boxfishes. This discovery offers new perspectives on the role of acoustic communication in the ...

Science has published two studies, led by an Ikerbasque researcher at the Achucarro Basque Center for Neuroscience and UPV/EHU, uncovering their unique evolutionary path. The pallium is the brain ...

The human brain is a marvel of evolution, enabling language, reasoning, and imagination. To uncover the roots of this complexity, scientists have studied brain structures across different species. The ...

This is when unrelated species evolve to have functionally similar features. All bats and birds "converged" with their ability to fly in response to environmental stimuli and biological goals. The arm ...

Homology as a hypothesis of evolutionary history with a simplified integration of terms reflecting the complex hierarchical modular organization of biological innovations. By mapping euthyneuran ...

Patricia Brennan has forged a controversial career in studying the twist and turns of the evolution of animal genitalia. A biologist based at Mount Holyoke College in South Hadley, Massachusetts, her ...
