Meta-Ethics; Is the theory of emotivism compartible with evolutionary theory?

support the claim that emotivism is compatible with evolutionary theory.The essay content should include An examination of the theory’s main position with sufficient examples Examine the assumption that moral truths/judgements are neither logical or empirical,the dramatic effect it would have on ethics if emotivsm were true. Did the emotivists prove it or just declare that it is obviously so?(need to be critical) Lastly critically examine if the theory of emotivism is compatible with evolutionary theory. Why do people engage in this form of practice? Is there a way to verify or test ? if it is biological what would follow? Are there other evolutionary theory that would destroy it (emotivism)? Examples are required for more understanding .
