Among the most interesting challenges in evolutionary biology is the attempt to identify the molecular mechanisms of gene expression that drive morphological evolution. The field is in the process of gaining a better understanding of a host of complex systems within individual cells.
确定驱动形态进化的基因表达的分子机制堪称进化生物学最有趣的挑战。上述研究领域试图更好地了解个体细胞内一系列复杂的系统过程。上述分子系统处在试验胚胎学的核心位置——DNA序列差异无法解释的基因功能改变是试验胚胎学的研究内容。
