Cornel Wilde-scary movie!

-20 20 I bet on the Husky
Plus 20 degrees is 68 degrees-these tests were done at 95+ degrees.
The dumping heat advantage would be much less at more reasonable temps
In fact at 20 degrees I would bet on the deer-might bet on the deer at most temps
and Wolves cover lots of ground-hell they might actually use the run your prey to exhaustion technique-
but not many wolves in 100 degree temps

Wasn't it cooler in Africa 250,000 years ago??
3.6 mph-just a walk-
why would we need 8-10 mph 100 degree long distance endurance if this "works" at 3.6 mph (average)?? Seems excessive?
And just how are they killing these deer once they run them down??
If they are spearing it-my guess-obvious question is why didn't they ambush it with a volley of spears-just wait for it to bleed out?
So how do these Kalahari kill them?
