Studying evolution by focusing solely on fossils would leave many questions unanswered, but evolutionary developmental biology (otherwise known as "evo-devo") helps fill in the gaps.
Five-hundred million years ago, it was relatively safe to go back in the water. That's because creatures of the deep had not yet evolved jaws. In a new pair of studies in eLife and Development, scientists reveal clues about ...
Vertebrate evolution was accompanied by two rounds of whole genome duplication followed by functional divergence in terms of regulatory circuits and gene expression patterns. As a basal and slow-evolving chordate species, ...
The human middle ear—which houses three tiny, vibrating bones—is key to transporting sound vibrations into the inner ear, where they become nerve impulses that allow us to hear.
A fossilized lower jaw has led an international team of paleontologists, headed by Bastien Mennecart from the Natural History Museum Basel, to discover a new species of predator that once lived in Europe. These large predators ...
Gathering vision data for hundreds of vertebrates and invertebrates, U of A biologists have deepened scientists' understanding of animal vision, including the colors they see.
A new study from biologists at The University of Texas at Arlington and an international team of collaborators provides the first comprehensive explanation of how snake venom regulatory systems evolved—an important example ...
The Evolutionary Morphology Laboratory led by Shigeru Kuratani at the RIKEN Cluster for Pioneering Research (CPR) in Japan, along with collaborators, has found evidence that the mysterious ancient fish-like vertebrate Palaeospondylus ...
Having a head is quite an advantage. Although this may sound banal, it had to be tested in a long evolutionary process: As animal life developed, invertebrates initially dominated the oceans. These had already developed head ...
We need zinc: one-tenth of the proteins in our cells require this metal for their normal functions in all aspects of cell metabolism.
