Scientists in Australia have unearthed beautifully preserved fossilized hearts and other internal organs of ancient armored fish in a discovery that provides insight into the evolution of the bodies ...

These days, all fish have teeth. The shapes of their teeth vary according to diet, ranging from the little pegs of goldfish ...

Vertebrate morphology exhibits remarkable diversity, reflecting a complex interplay of developmental processes, genetic regulation and environmental pressures. This variation arises from a combination ...

A harlequin poison dart frog (Oophaga sylvatica) is pictured at the Tesoros de Colombia (Treasures of Colombia) sustainable farm in Nocaima, Cundinamarca department, Colombia, on July 9, 2024.

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 ...

Learn how increased protein diversity in signaling genes may have helped drive the shift from invertebrates to vertebrates, reshaping how animals with a spine evolved. From frogs and fish to birds and ...

Vertebrates produce diverse proteins from single genes, unlike invertebrates. This protein diversity helps vertebrates develop complex organs and cell types. University of St Andrews research offers ...

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 ...

In DNA, retrotransposons can move around and insert themselves into other parts of genomes with a kind of copy and paste mechanism. Most have lost this ability in humans, but they still make up a ...

Researchers have provided the first experimental evidence that brain regions can evolve independently of each other during cognitive evolution. This so called mosaic brain evolution was verified ...
