A massive multiomics study of Atlantic salmon and rainbow trout shows that developmental constraints, particularly at the ...

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 ...

Invertebrate research bias in ecology is measurable and worsening: a new audit of 1.38 million papers across 612 journals by ...

As our species (Homo sapiens) evolved and spread across the globe, they were contemporary with several other hominins. These include the best-known of our evolutionary cousins, the Neanderthals, but ...

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 ...

Assumptions that may seem self-evident are not always accurate when it comes to the evolution of vertebrate brains. Researchers at the University of Bayreuth have now demonstrated this by examining ...

Researchers report in the journal Cell that ancient viruses may be to thank for myelin—and, by extension, our large, complex brains. The team found that a retrovirus-derived genetic element or ...

This article predates the current owners of Science Blog. It has not been reviewed under the current editorial process and is kept as part of the archive. One of just two vertebrates without a jaw, ...

Deuterostome phylogeny: the context for the origin and evolution of the vertebrates / Henry Gee -- Amphioxus and the evolutionary origin of the vertebrate neural crest and the midbrain/hindbrain ...

The colonization of the pelagic realm by the vertebrates represents one of the major transitions in the evolutionary success of the group and in the establishment of modern complex marine ecosystem.

Researchers report that ancient viruses may be to thank for myelin -- and, by extension, our large, complex brains. The team found that a retrovirus-derived genetic element or 'retrotransposon' is ...
