Bats can hear frequencies that we cannot perceive.

Dogs – they can smell what we can’t: For example, whether a person has cancer. Scientists want to imitate this ability with an odour sensor. This is of incomparable value for early medical diagnosis.

Same senses – but different capacities?

Recently I read in an article that research is being done into whether animals see other things than we do. The question is obvious: If the senses of hearing, smell and touch function differently – why not vision as well? Do we see the world selectively? Do they see the same world as we do?

What of what we see is true?

Philosophers have been discussing this for centuries – epistemology. If you found out that animals see something different than we do – what could that be?

Colours? Objects or also – alien beings?
