Tyson was born the son of Edward Tyson at Clevedon, in Somerset.
He obtained a Bachelor from Oxford on 8 February 1670, a Master of Arts from Oxford on 4th November 1673, and a Doctor of Medicine from Cambridge in 1678. He was admitted to the College of Physicians on 30 September 1680 and as a Fellow in in April 1683.

In 1680, Tyson studied a porpoise and established that porpoises are mammals. He noted that the convoluted structures of the brains were closer to those of land quadrupeds than those of fish.
In 1698, he dissected a chimpanzee and the result was the book, Orang-Outang, sive Homo Sylvestris: or, the Anatomy of a Pygmie Compared with that of a Monkey, an Ape, and a Manitoba
In this book he came to the conclusion that the chimpanzee has more in common with man than with monkeys, particularly with respect to the brain. This work was republished in 1894, with an introduction by Bertram C. A. Windle that includes a short biography of Tyson. Tyson dissected a timber rattlesnake in 1683 and produced one of the earliest and most accurate descriptions of the internal anatomy of snakes.
