Final answer:
No evidence is provided to substantiate the claim that South African music therapy research recommends separate groups for music therapists and musicians; instead, research highlights music's universality and group cohesiveness.
Step-by-step explanation:
The statement regarding the results of South African music therapy research suggesting that music therapists and musicians should run separate groups is not supported by the information provided. The given research emphasizes the universal language of music and its ability to convey emotions across cultural boundaries. The studies by Thomas Fritz and references to Darwin's theory primarily highlight music's capacity to foster a sense of wholeness within groups, suggesting that collaboration in music can be more effective than separation. Additionally, there is no direct mention of South African music therapy research, making it impossible to ascertain the truth of the statement without additional context.
