Where did STI/STDs come from? Since they are created via giving to someone who has already contracted it
So where did they originate from?
In: Biology
STDs are actually caused by tiny things we call microorganisms and viruses. These tiny things were around for a very long time before human life ever evolved. And even as we evolved, so did they. In fact, these tiny things evolved a way to live in, and hitch a ride on, our bodies in order to survive and make more of themselves. Similar to sneezing/coughing when you have a cold, STDs are transmitted from body-to-body in whatever way they can hitch a ride.
