Description
Hi,
I have two ancient samples (7X and 13X) . In NJ tree , they get together with groupA . But in Outgroup f3 statistic ,the groupB's f_3 value is higher than gourpA ,How to explain the result ?
The NJtree may like this:

The output :
result: Ancient groupB outgroup 0.235691 0.001944 121.244 12220407
result: Ancient groupA outgroup 0.231413 0.001914 120.894 11370158
Thanks!
