Characterization of endogenous and human contaminant reads in faunal BAM files. a Comparisons of PMDR and mRL for all mammoth samples. b mRL for mammoth sequences mapping to the elephant or the human parts of the concatenated reference (Wilcoxon rank-sum test, W = 313.5, p-value = 0.00223). c PMDR for mammoth sequences mapping to the elephant or the human parts of the concatenated reference (Wilcoxon rank-sum test, W = 397, p-value = 1.016e-10). d Comparisons of PMDR and mRL for all ancient dog samples. e mRL for dog sequences mapping to the dog or the human parts of the concatenated reference (Wilcoxon rank-sum test, W = 1929, p-value = 1.251e-08). f PMDR for dog sequences mapping to the dog or the human parts of the concatenated reference (Wilcoxon rank-sum test, W = 1743, p-value = 1.511e-05). In all cases, **: p-value < 0.01 and ****: p-value < 0.0001
