And it can have one, once it gets really tired and we catch up to it. Course then we'll be hitting it over the head with a club and eating it.

It has several already

>>Good luck.

Yup, they're fast and can run long distances, well, fast. Humans aren't as fast but can run for longer. This is the point; we're not the fastest species, but we can run for longer than any other. An ostrich will get tired before a human.

Now we're not talking about a you-an-me human. We're talking hunter-gatherer humans.

Not many humans run longer than a marathon. That's kind of our baseline long distance.

That's our modern, civilised human baseline, maybe. Our ancestors, who did chase animals to exhaustion, would laugh at our mere marathon.

Doubtful. Our ancestors chased food for survival. Racing an animal for that far isn't very efficient. The first recorded guy to run a marathon (to Marathon) died of exhaustion. We have so many resources that people do it for leisure.

The fact that marathon running is an Olympic event that people train for their entire lives directly disputes your comment. Not to mention the fact that ultra marathons also exist.

Our ancestors would be like "but why?"

Again, you're talking about modern humans.

You can read about this hypothesis here. There are critiques of it, but those are of the evolutionary path, not the fact that humans are amazing endurance runners.

He said endurance, not sprinting and the such. Endurance is how long you last regardless of speed. And ostrich is fast but couldn't last.

I mean. If you think you can out endurance an ostrich, go ahead.
