Chimpanzees, for example, which are a promiscuous species, had more advanced evolution of a gene controlling the stickiness of semen than gorillas, which tend to be monogamous and stay faithful to their partner for life.
They discovered a gene called SEMG2 that controls the production of a component of semen, called semen coagulum, that acts like a glue.
The idea to mass produce a biodegradable and nature friendly glue was born.
It was found that the SEMG2 gene was present in other species as well like horses and oxen. Experiments began to test the adhesive properties of their semen.
Three years later KrazyGoo was created. The only fully biodegradable glue made purely from pasteurized horse and oxen semen.
