Photos That Will Make You See The World Differently - The Curious Human

There is a theory that the giraffe's neck is not only a practical survival adaptation however, but has a sexual dimension as well..Here, by an interesting coincidence, it still echoes the development of the human brain. As well as being useful for reaching greater heights the giraffe's neck is also a useful sexual appendage (just like our intelligence): it is used by males for the purpose of impressing the opposite sex (just like our intelligence), and is also deployed by males as a weapon against members of the same sex (just like our intelligence). Male giraffes fight each other by swinging their long necks and using their heads as clubs in very much the same way that male humans use their heads (or at least the brains in their heads) as clubs to bludgeon each other at a psychological level.
