People are underestimating the techniques used in ultimate fighting, particularly the submission holds.

If you've seen the original UFC's (1-4), nobody knew which martial arts actually worked and there were no weight classes or time limits. In these matches it became very evident how effective jujitsu is when a 170lb guy named Royce Gracie defeated opponents much larger and more athletic.

Nowadays, all the UFC fighters know what martial arts and techniques work and essentially use the same techniques (jujitsu/wrestling on ground and Mui-Thai kickboxing on feet). Therefore in the fights you see there's a lot of subtle defensive moves going on, and it's more striking lately (also due to the rules, judges decisions, and timelimits).

My points is that most people have no idea how effective jujitsu is on an untrained opponent. I have experience with this. A jujitsu expert could probably beat any untrained human on the planet in a life and death scenario.

The same submissions can be applied to a chimp, since their body is pretty similar to a human's.
