The importance of non-additive interaction between epistatic alleles in forming population adaptability has long been a controversial topic, partly due to the lack of empirical evidence.

This is a good leading sentence. It not only states the theme: the role of cognition in shaping group fitness, but also explains the lack of empirical evidence in this field.
