TL;DR: By phylogenetic analysis, the evolutionary origin of 675 Tetraodon duplicated genes assigned to chromosomes are determined, showing that similar mechanisms are at work in fishes as in yeast or plants and provide a framework for future investigation of the consequences of duplication in fishes and other animals.

TL;DR: It is shown that a TH derivative, triiodothyroacetic acid (TRIAC), induces metamorphosis in the cephalochordate amphioxus, and conservation of a regulatory network supports the homology of metamorphotic in the chordate lineage.

TL;DR: Following the spawning behavior of the European amphioxus during two spawning seasons, it is shown that animals in the field spawn approximately from mid-May through early July, but depending on the year, they show different patterns of spawning.

TL;DR: A systematic study of transcription factor binding and gene expression in blastoderm embryos of four species, which sample much of the diversity in the 40 million-year old genus Drosophila, found that mRNA levels are much better conserved than individual transcription factorbinding events, and that changes in a gene's expression were poorly explained by changes in adjacent transcription factors.

TL;DR: The hypothesis that the giant panda was the first species to diverge among ursids is definitively confirmed and the precise branching order within the Ursus genus is clarified for the first time.
