2009/12/15
When Darwin's finches diverged from their common ancestor, the isolation of their island home allowed many species to arise from one.When their dinosaur ancestors emerged in the Triassic, the island h...
摘要
进化生物学和发育生物学的结合产生了一门新兴学科——进化发育生物学,近年来该领域研究取得了丰硕的成果。头索动物文昌鱼是现存生物中最近似于脊椎动物直接祖先的生物,在与脊椎动物分化后形态改变很小,其基因组未曾经历大规模的基因组倍增,在一定程度上反映了脊椎动物祖先型基因组的特征,但在漫长的独立进化历程中基因组自身还是经历了一些变化。本文介绍了在几例在文昌鱼支系中独立发生的基因倍增事件(Hox; E...
