I am working with the VP2 protein DNA of carnivore parvoviruses and sequences are only of 1300bp. I obtained the following phylogenetic tree (Maximum likelihood, 1000 replicates) and the reviewer has a the following concern: he thinks there could be homoplasy among my sequences (marked with blue), instead of cross species transmission (all animals live in the same area). I would be very grateful if somebody could explain me his view and how he arrived to this conclusion. Further he wants statistical values to distinguish convergent evolution from cross-species transmission, so I think the bootstrap values in the tree are not useful.

I would like to know if this has any sense or how I need to refute (do I need to calculate CI values?)
