Historical demography
Significantly large negative values of Fu’s Fs test rejected the
null hypothesis of neutral evolution of the cytochrome b marker
for the population group in Region 2. This could indicate population
expansion in Region 2, which is supported by the mismatch
distribution analysis and Rogers test of sudden population expansion
(Rogers, 1995; Table 1). The value of s for the Region 2 population
group was 13.966 (Table 1). For the substitution rate for a
variety of lizards were in a range of 0.005–0.010 site1 myr1, the
expansion time was estimated to be between 1.043 and 2.087 mya
