Comparison of the estimated values of parameter θ, mutation rate μ (per sequence), and effective population size N_e

Parameters	Estimated values
	Chimpanzee vs. Human				Orangutan vs. Human
Divergence time, Myr	5	6	7		12	14	16
μ (×104)	2.69	2.24	1.92		2.32	1.99	1.74
θ (Ne = 10,000)*	10.76	8.96	7.68		9.28	7.96	6.96
Ne (W)†	12,200	14,600	17,000		14,100	16,400	18,800
Ne (T)‡	8,100	9,700	11,300		9,400	10,900	12,500

^*θ was estimated by θ = 4 N_eμ using N_e = 10,000. 

^† N_e (W): the N_e value estimated by θ/4μ using Watterson's (10) θ value (13.09). 

^‡ N_e (T): the N_e value estimated by θ/4μ using Tajima's (11) θ value (8.70).
