有篇阅读：Everybody loves a fat pay rise. Yet pleasure at your own can vanish if you learn that a colleague has been given a bigger one. Indeed, if he has a reputation for slacking, you might even be outraged. Such behaviour is regarded as“all too human”, with the underlying assumption that other animals would not be capable of this finely developed sense of grievance. But a study by Sarah Brosnan and Frans de Waal of Emory University in Atlanta, Georgia, which has just been published in Nature, suggests that it all too monkey, as well.

请教老师一个问题：红色字体中with the underlying assumption that other animals would not be capable of this finely developed sense of grievance. 答案的解释翻译为

：言下之意是，其它动物不具备这种高度发达的意识，

而我的翻译是：但这种潜在的假定是，其它动物不具备这种高度发达的意识

请问这种翻译符合要求吗？直译不少句子不好译出，意译又怕出错违反原意，请问老师在这方面有何心得，请略微举例说说，谢谢。
