Science Has Finally Discovered Why Men Exist

Since in many species, sperm is males’ only contribution to reproduction, biologists have long puzzled about why evolutionary selection, known for its ruthless efficiency, allows them to exist.

Now British scientists have an explanation: Males are required for a process known as “sexual selection” which helps species to ward off disease and avoid extinction.

Also jars. Those damn jam jars can be just too hard to opens. And then I’d be sad without jam.
