Puzzler Number 3

For this puzzler, I am looking for an answer to a simple question – what is the most dangerous animal to humans? In other words, what animal has been responsible for more human deaths over all of human history? Yes, this animal has a common name. For bonus points, what is the second most dangerous animal to humans?
