Does anyone know which is the other purebed male apart from 'Ricky' (who seems very unlikely to breed now)?
I would also be interested to know exactly how precise the science can be that these are really purebred West African chimps. Is it 100% certainty?
I can foresee big introduction problems too- as stated in the press article -because this is a long establish group which is likely to repel newcomers vigorously. Maybe the purebred animals will have to be initially split into a subgroup to balance the mix of new/old animals better and so make the introductions workable.
