for example we are not sensitive to ultraviolet light, but bees are. they also have 4 colur vision as the recptors in tehir eyes are wired differently to ours.
some birds have a magentic sense that we do not have
This is a really interesting question! I think this is possible – our senses are pretty limited if you compare us to other animals 🙂 for example, bats can sense ultrasounds, which are way beyond human hearing and we would have to have different type of ears to be able to detect that
We do y necessarily need an organ to detect certain phenomena. You could imagine, as we already do with ultraviolet and magnetic fields, that we simply need to change the information format to something that we can detect!!
