Early humans won at running; Neandertals won at walking

(PhysOrg.com) -- New research has compared the performance of the heels of modern-day distance runners to the heels of Neandertals and ancient Homo sapiens. The results show the Neandertals' heels were taller than those of modern humans and Homo sapiens, and more adapted to walking than running over long distances, while those of Homo sapiens were more adapted to endurance running.
Assistant Professor of Anthropology, Dr David Raichlen of the University of Arizona in Tucson, and colleagues, found that unlike modern humans, the Neandertal heel was taller would have provided less spring during running, and speculated that the heel probably stabilized the ankle and helped in jumping and walking uphill. In modern humans the heel is lower and stretches the Achilles tendon and increases its ability to act like a spring and reduce the consumption of energy.
Dr Raichlen and colleagues had eight distance runners run on a treadmill at 10 mph (16 km/h) for periods of 10 minutes and calculated their rates of oxygen consumption. In different running periods, they also took magnetic resonance imaging (MRI) scans of their heels and Achilles tendons.
The results showed the heel bones were shorter and lower in the runners whose oxygen consumption while running was most efficient.
The heel measurements were compared with those of 13 fossil Homo sapiens dated from 30-100,000 years ago and with six Neandertals from around the same period. The researchers calculations suggest that during running the Homo sapiens would have expended 6.9% more energy than modern distance runners, but Neandertals would have needed an average of about 11.4% more energy.
The results suggest that while Neandertals may not have fared well in long-distance marathons, their bone structures would have given them an advantage in walking and in activities requiring great strength.
The results of the research support earlier findings that long-distance running in Homo sapiens evolved over two million years ago and probably helped early humans in hunting before spears began to be widely used about 400,000 years ago. The ability to run long distances in hot environments is thought to help in running prey to exhaustion. Neandertals lived in colder climates and probably needed different skills in hunting.
The paper was published in the Journal of Human Evolution.

There's one adaptation we have that (i think) no other animal has. The ability to sweat. We're not fast, we're not strong, but we can run forever compared to other animals, even in advanced age. To me, it is a reasonable assumption that the way we dealt with grassland was to spot our prey from far off and run it to exhaustion with the entire social group in tow.

What was the advantage of longdistance walking for the Neanderthals? Did they use their brains more for catching pray with tactics? Or were they stealthy instead of quick? Did their diet consist of berries, leaves and other edible static resources, or did they mostly searched the land for already dead or sick animals?
They must have had a pretty good way to getting their food, but I'm really wondering which it was.

I'm pretty sure horses sweat. And generally, most of the hoofed animals are much better long-distance runners than humans.
I'd even go farther and say that most four-legged animals are better runners than humans, period. I mean, try and go for a run alongside a wolf; see who passes out from exhaustion sooner...
If running was key to the hunting activities of the early Homo Sapiens, then it would imply they would have preferentially hunted slow-moving prey that's only good at sprinting. Things like boars. Or other great apes, perhaps...
On the other hand, early Homo Sapiens was at least as much a prey as predator, particularly on the steppes of Africa. Perhaps running was merely a way to elude roving packs of hyenas, big cats, and other similar threats -- particularly the sort of predators that can track your scent and thus give chase over long distances.
Then there's fight-or-flight. Sometimes it's easier to survive a conflict by running away...

As for wolves, yes, they run faster, but all species of canis cannot run extended distances. When it comes to running, we are certainly in a league of our own. Our anatomy only indicates running as a primary activity. (cont).

I have two greyhounds, and I take them jogging every morning. These dogs are retired racers, and a heckuvalot faster than I am. But I don't take them more than about a mile, as they begin to pant so hard they look like they're about to explode. Greyhounds aren't going to be finishing any marathons.

Interesting. We have dogs that are more timber / arctic wolf like. They run and run and run and run and just keep on going. Ours work on our farm as herding and guarding dogs. They can do very fast bursts but generally they do long distance running. They'll run our perimeter which can be miles up and down the mountains. Wolf vs Greyhound tactic. Us vs Neanderthal. Lots of room in evolution and the world for many wonderful variations.

Thats because we are tropical while they most likely had become a more temperate species. Our reproduction was not correlated with the seasons. If so, we could easily have out-reproduced them (and our resources.)
Inuits can stand motionless over a seal breathing hole in the ice for 6 hours or more. Running down prey is less useful in the snow.

A man can outrun a horse over any significant distance. It's been done over and over. As the distance increases, humans will get further and further ahead. Only 30 miles per day? My brother is an ultrarunner, and on *mountainous* terrain has covered 100 miles in a race in under 24 hours. He has run daily marathons for a week without a problem. The Tarahumara have been known to run 80 miles per day in 90-100 degree weather. A horse would be down after 10 miles.

You guys are using hyperbole. Humans CANNOT outrun all animals even over distance. On HOT days some YOUNG Africans do try to run down SOME animals. Mostly it seems to be species that overheat. Some humans can and do run over a hundred miles a day for several days at altitude but it is more of a jog. Don't remember why but it was in the Andes. They have HUGE lungs and I think that heat is not much of an issue.
I suspect the big advantage the humans had on the Veld was the ability to go out in the Noon Day Sun. As for Neanderthal I don't think we outran them. Lots of things must have been involved but I recall that Neanderthal has a shoulder muscle that is arranged for power in such a way that it would make them lousy with thrown weapons. Chimps can't throw well either despite the long arms.

@SH,
Here's the thing about running prey to exhaustion: it's very doubtful that the running anatomy emerged in full glory ex nihilo. It must've been a gradual process of refinement, which means that for a long period of time our ancestors were very mediocre runners. Question is, what natural pressure(s) could've selected for those traits anyway, even while the traits weren't yet refined enough to be useful for hunting?
One possibility might be carrion (you see a couple of vultures circling on the horizon; the faster you get there, the better the odds of finding a corpse that hasn't been completely stripped yet...)

The dog is probably the best long distance runner. They can run all day to run down prey.

If you are implying that we were carrion eaters I think you are wrong for a couple reasons. First, carrion eaters are generally evolved to resist almost any kind of bacteria found in a dead body, we aren't. Carrion eaters have specialized mouth parts to eat meat, we lost our canines before we learned how to run. Most dead bodies have the predator around that probably killed it. If we had the means to take the prey from a predator, we had the means to kill prey ourselves in the first place. Monkeys don't eat carrion, they go out and kill something when they want meat, including other monkeys. Sounds like a family trait.
We were not carrion eaters to any extent that changed our physiology.

You are wrong on both counts. Running all day is exactly what dogs were evolved to do, they are not ambush predators, they don't hide, they chase. That is why they evolved their incredible sense of smell, to stay on the trail and run down prey.
We aren't talking burst running which people are selectively mixing up with a trot or lope. Many other animals like antelopes or even Bison can run all day. We are by no means in a league of our own or the best.
