Scientists have investigated lamprey embryos using cutting-edge microscopic techniques to reveal interesting insights about vertebrate head evolution, clarifying an unresolved mystery in basic science ...

In the limestone ranges of Western Australia’s Kimberley region, near the town of Fitzroy Crossing, you’ll find one of the world’s best-preserved ancient reef complexes. Here lie the remnants of ...

Researchers at University of Tsukuba and their collaborators have conducted a comprehensive analysis of the olfactory receptor repertoire of the hagfish (Eptatretus burgeri), a jawless vertebrate.

Because we’re a member of the group, it’s easy to see vertebrates as the pinnacle of evolution, a group capable of producing bats, birds, and giant whales in addition to ourselves. But when they first ...

The researchers hope that their discovery is an important step towards eventually understanding the process behind the origins of vertebrate jaws. The study was conducted in collaboration with ...

Researchers have long assumed that a tube in the famous Pikaia fossil ran along the animal’s back. But a new study turned the fossil upside down. By Carl Zimmer Over the past 500 million years, ...

Whole-genome duplications are rare evolutionary events in which all the chromosomes and genes of a species are doubled. This supplies new genetic material to the gene pool and can provide an ...

The researchers from the HiLIFE Institute of Biotechnology, University of Helsinki compared two central bearded dragon lizards (Pogona vitticeps): a normal one and a mutant with no body scales. They ...

Fairbanks, Alaska—University of Alaska Fairbanks scientists have identified what they think is the ancestral trait that allowed for the evolution of air breathing in vertebrates. They will present ...

The origin of the vertebrate skull is a topic of much debate among evolutionary biologists. Some believe that the vertebrate head has developed as a result of modification of the segmental elements of ...
