David Attenborough not denying existence of yeti

David Attenborough has a healthy attitude toward science and its development.
He keeps an open mind about yeti or abominable snowman in the Himalayas or Big Foot in N. America and does allude to their existence.
Nonetheless, he is advocating the pseudo-science of “global warming,” which is disappointing.

In 1959, nine Russian students disappeared during their hike in the Ural Mountains which form the artificial boundary between Europe and Asia.
Their bodies were found later, mangled, and it was not the work of wolves or bears. Who done it?

Did the ape go extinct?
Maybe yes, maybe no.
