Is a science required at A-level to study Archeology and Anthropology at Cambridge?

my options are; English Language, Philosophy and Ethics, History and Psychology. i have looked at the Cambridge website and to take the social sciences and arts as they are listed, there are a combination of courses listed as being 'good keystones' and all of my choices are present there. would it be better if i added Biology to my list? as a science may be seen as more beneficial, i am wondering if anyone can tell me if a science is recommended, or if im fine with what i have. thanks! :D
