Stargate SG-1/Land of the Lost Trivia

I'm watching Stargate for the first time, having caught an episode here or there in the past. One character that jumped out at me immediately was "Chaka", as mentioned in the footer text in yesterday's cartoon.

On Stargate, Chaka was an Unas.

I, of course, was more familiar with Chaka from Land of the Lost, who was a Pakuni, which sounds similar enough as far as race names go.

I waited for Ta and Sa to pop through the Stargate, but they never did.
