There had been lot of theories but to every theory there had strong counterpoint found. For example, speech, language and math was considered unique to humans but several animals have been found to speak, have elaborate language and even do counting and addition. Then there was belief that animals can’t do counterfactuals, for example, making decisions based on simulating what-if scenarios but that also has been proven false.

There is book written on this subject that argues that most fundamental human abilities not yet seen in animals is building nested scenario such as telling a fictional story and desire to share knowledge among each other:
