Abstract: The most popular tools for analysing the large scale distribution of galaxiesare second-order spatial statistics such as the two-point correlation functionor its Fourier transform, the power spectrum. In this review, we explain howour knowledge of cosmic structures, encapsulated by these statisticaldescriptors, has evolved since their first use when applied on the early galaxycatalogues to the present generation of wide and deep redshift surveys,incorporating the most challenging discovery in the study of the galaxydistribution: the detection of Baryon Acoustic Oscillations.
