The "boring billion" shaped multicellularity, with energy demands sparking complexity. This era shows evolution's cost.

Between 1.8 billion and 800 million years ago, earthly life was in the doldrums. During this period, called the "boring ...

A research group at University of Tsukuba has discovered that the entrance to the gut (pylorus) and the exit (anus) of sea urchin larvae open in response to light, each to different wavelengths. This ...

The oldest fossil evidence of multicellular animals, or metazoans, are burrows that suggest smooth, wormlike creatures live 900 mya or more. Found in rocks in China, Canada, India, and elsewhere ...

In a new study, Arizona State University researcher Michael Lynch explores the substantial energy demands required to maintain and evolve multicellular life. The study, using the water flea Daphnia as ...

This choreography is remarkably evolutionarily conserved across all animals, and it presumably already existed in the last common ancestor of metazoans (the collective term for animals ...

The genome sequence of the sponge Amphimedon queenslandica shows that early metazoans possessed several Hox-like genes of the NK family, but Hox genes themselves arose and expanded only after ...

For mRNA decapping by enhancing DCP2's mRNA-binding affinity and regulating distinct biological processes through DCP1a and DCP1b, human DCP1 is essential.

This important manuscript provides insights into the competition between Splicing Factor 1 (SF1) and Quaking (QKI) for binding at the ACUAA branch point sequence in a model intron, regulating exon ...
