Abstract:
Eric Davidson had a deep and abiding interest in the role developmental mechanisms played in generating evolutionary patterns documented in deep time, from the origin of the euechinoids to the processes responsible for the morphological architectures of major animal clades. Although not an evolutionary biologist, Davidson\'s interests long preceded the current excitement over comparative evolutionary developmental biology. Here I discuss three aspects at the intersection between his research and evolutionary patterns in deep time: First, understanding the mechanisms of body plan formation, particularly those associated with the early diversification of major metazoan clades. Second, a critique of early claims about ancestral metazoans based on the discoveries of highly conserved genes across bilaterian animals. Third, Davidson\'s own involvement in paleontology through a collaborative study of the fossil embryos from the Ediacaran Doushantuo Formation in south China.
摘要:
埃里克·戴维森对发展机制在产生进化模式中所扮演的角色有着深刻而持久的兴趣,从Euechinoid的起源到负责主要动物进化枝的形态结构的过程。虽然不是进化生物学家,戴维森的兴趣早于目前对比较进化发育生物学的兴奋。在这里,我讨论了他的研究与进化模式之间的交叉点的三个方面:第一,了解身体计划形成的机制,特别是那些与主要后生进化枝早期多样化有关的。第二,基于在双边动物中发现高度保守的基因,对祖先后生动物早期主张的批评。第三,戴维森通过对中国南方EdiacaranDoushantuo组的化石胚胎的合作研究,自己参与了古生物学。
