In their letter, Torroni et al. (2000) express a radical disagreement with the assumptions, methods, and conclusions of Simoni et al.’s (2000) article. We think that their many criticisms can be reduced to four points: 1. Haplogroups have been incorrectly defined, and therefore the spatial autocorrelation analysis (SAAP) of their frequencies is flawed; 2. Aside from these errors, the frequencies of haplogroup J and of superhaplogroup JT do not match previous reports; 3. Only 22 polymorphic sites have been considered, and therefore the results of AIDA are flawed; 4. Meaningful patterns of mtDNA diversity can only be identified by the analysis of the distributions of recent mutations.

Abstract
In their letter, Torroni et al. (2000) express a radical disagreement with the assumptions, methods, and conclusions of Simoni et al.’s (2000) article. We think that their many criticisms can be reduced to four points: 1. Haplogroups have been incorrectly defined, and therefore the spatial autocorrelation analysis (SAAP) of their frequencies is flawed; 2. Aside from these errors, the frequencies of haplogroup J and of superhaplogroup JT do not match previous reports; 3. Only 22 polymorphic sites have been considered, and therefore the results of AIDA are flawed; 4. Meaningful patterns of mtDNA diversity can only be identified by the analysis of the distributions of recent mutations.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
