阿舍利的双面形状和对称性引发了许多关于过去人类行为的讨论，涉及双面技术的“意义”。然而，很少有研究试图量化和调查他们的历时关系，使用大量的阿舍利双面孔数据集。使用英国考古记录作为案例研究，我们首先进行椭圆傅立叶分析双面轮廓量化和更好地了解双面形状和个别间冰期之间的关系。使用提取的傅立叶系数，我们然后详细的对称性在整个这一时期的性质，在平行调查的形状和对称性。大小（通过双面长度）作为双面形状和对称性的一个因素的重要性也被考虑。结果突出了海洋同位素阶段（MIS）13的高水平对称性，其次是通过英国阿舍利的不对称性增加。其他观察结果包括一般转移到'点'的形式在MIS 9和7和重要性的大小在高双面对称水平。本文最后讨论了潜在的重要性，二次沉积和palimpumps网站在扭曲观察到的关系在整个旧石器时代。
Acheulean biface shape and symmetry have fuelled many discussions on past hominin behaviour in regards to the ‘meaning’ of biface technology. However, few studies have attempted to quantify and investigate their diachronic relationship using a substantial dataset of Acheulean bifaces. Using the British archaeological record as a case study, we first perform elliptic Fourier analysis on biface outlines to quantify and better understand the relationship between biface shape and individual interglacial periods. Using the extracted Fourier coefficients, we then detail the nature of symmetry throughout this period, before investigating both shape and symmetry in parallel. The importance of size (through biface length) as a factor in biface shape and symmetry is also considered. Results highlight high levels of symmetry from Marine Isotope Stage (MIS) 13, followed by increasing asymmetry through the British Acheulean. Other observations include a general shift to ‘pointed’ forms during MIS 9 and 7 and the importance of size in high biface symmetry levels. This article concludes by discussing the potential importance of secondary deposition and palimpsest sites in skewing the observed relationships throughout the Palaeolithic.
