Lancelets, or amphioxus, are small worm-like marine animals that spend most of their lives buried in the sea floor, filter-feeding through jawless, ciliated mouths. The vertebrate affinities of these ...

Those of you who took high school biology may remember the lancelet, also known as the amphioxus. Its simplified body plan is notable for containing a number of features that it shares in common with ...

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 ...

(Phys.org) -- An evolutionary leap made at the bottom of the ocean over 500 million years ago gives new insights into the causes of human diseases such as diabetes, cancer and neurological disorders, ...

Probing the mysterious glow of light produced naturally by animals, scientists have deciphered the structural components related to fluorescence brightness in the primitive sea creature known as ...

Research on the genome of a marine creature is shedding new light on a key area of the tree of life. Because amphioxus is evolving slowly -- its body plan remains similar to that of fossils from the ...

The genome sequence of a species of amphioxus, an iconic organism in the history of evolutionary biology, opens up a fresh vista on the comparative investigation of chordates and vertebrates. The ...

Para abordar este tema, antes que nada, es importante darnos una idea de lo que es la notocorda. Pues es nada más y nada menos que el precursor de la espina dorsal, es una estructura embrionaria que ...

Research on the genome of a marine creature led by scientists at Scripps Institution of Oceanography at UC San Diego is shedding new light on a key area of the tree of life. Linda Holland, a research ...
