What makes us human? Specialists in each discipline respond through the lens of their own expertise. In fact, 'anthropogeny' (explaining the origin of humans) requires a transdisciplinary approach that eschews such barriers. Here we take a genomic and genetic perspective towards molecular variation, explore systems analysis of gene expression and discuss an organ-systems approach. Rejecting any 'genes versus environment' dichotomy, we then consider genome interactions with environment, behaviour and culture, finally speculating that aspects of human uniqueness arose because of a primate evolutionary trend towards increasing and irreversible dependence on learned behaviours and culture - perhaps relaxing allowable thresholds for large-scale genomic diversity.
是什么造就了我们人类?各学科的专家都通过自身专业视角给出了回答。事实上,“人类起源学”(解释人类的起源)需要一种跨学科方法来避开此类障碍。在此,我们从基因组和遗传学角度看待分子变异,探讨基因表达的系统分析,并讨论一种器官系统方法。我们摒弃任何“基因与环境”的二分法,接着考虑基因组与环境、行为和文化的相互作用,最后推测人类独特性的某些方面是由于灵长类动物进化趋势,即对习得行为和文化的依赖不断增加且不可逆转——这或许放宽了大规模基因组多样性的允许阈值。
