… In 1922, Walter Garstang placed the embryo back at the heart of evolution by arguing that
the origins of adult morphological novelties must often be traced back to changes in the …

… to be evolutionarily young hints at links between cellular … The range of these values may
be, at least in part, due to the … pressure to keep the exon length at ∼140 bp 10, approximately …

… We quantify divergence at different times during embryogenesis, and show that expression
… By fitting different evolutionary models to each gene, we show that at each time point more …
