Cuttlefish embryos reveal that cephalopod mollusks evolved specialized arms and tentacles by activating the same genetic circuits that control development of limbs in arthropods and vertebrates.
The animal phylogeny of glutamate receptors indicates that vertebrate types do not account for all receptor classes originated during evolution, neither are they the pinnacle of a linear evolutive process.
No discernible latitudinal diversity gradient in rocky intertidal α-diversity as local-scale physical and biological processes outweigh global-scale environmental gradients.
Evolutionary reconstruction of the ecdysis pathway shows that its major elements are present in the majority of metazoans, providing evidence that they originated much earlier than currently assumed.
Ancient proteomes from tiny shell ornaments were successfully characterised for the first time, showing the unexpected use of mother-of-pearl from local riverine molluscs in both coastal and inland prehistoric sites.
Homology of vertebrate skull structures should be based on evolutionary continuity and an appreciation of germ layer origins and inductive signaling in the embryonic head.
