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.

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.

Reconstruction of cell-type families in the purple sea urchin larva reveals unprecedented transcriptional diversity, stunning neuronal complexity and a missing link to pancreas evolution, suggesting this approach can be also used to uncover hidden cell type homologies.
Quantitative, experimentally testable predictions allow discrimination between contraction mechanisms in disordered actomyosin and microtubule/motor bundles.
Prokaryotic TRADD-N and Death-like adaptor domains in diverse predicted apoptosis and immune systems from multicellular prokaryotes and metazoans indicate the common origin of key apoptosis mechanisms required for the stabilization of multicellularity.

A molecular profiling approach to quantify transcripts and proteins from identical samples allows study of molecular effects of maturation, sexual differentiation and the endogenous circalunar clock in a marine worm.
Interest in the ecology, biology and evolution of amphioxus is growing, and the availability of several species is helping to improve our understanding of chordate evolution.
Combined light and electron microscopy reveals a new function for Arp2/3-mediated actin assembly in nuclear envelope rupture, which leads to a separation of nuclear membranes and pores from the lamina.
