Comparing walking and running in persistence hunting

It has been proposed that humans' exceptional locomotor endurance evolved partly with foraging in hot open habitats & subsequently c 2 Ma with persistence hunting, for which endurance-running was instrumental,
but persistence hunting by walking (if successful) could select for locomotor endurance, even before the emergence of any running-related traits in human evolution.
Using a heat exchange model validated here in 73 humans & 55 ungulates, we simulated persistence hunts for prey of 3 sizes (100, 250, 400 kg) & 3 sweating capacities (non-sweating, low, high) at 6237 combinations of hunter's velocity (1–5 m/s,
intermittent), air-Tp (25–45 °C), rel.humidity (30–90 %) & start time (8:00–16:00). Our simulations predicted that walking would be successful in persistence hunting of low- & non-sweating prey, esp. under hot & humid conditions,
but simulated persistence hunts by walking yielded a 30–74 % lower success rate than hunts by running or intermittent running.
Despite requiring 10–30 % less energy, successful simulated persistence hunts by walking were twice as long, and resulted in greater exhaustion of the hunter than hunts by running & intermittent running.
These shortcomings of pursuit by walking vs running identified in our simulations could explain why there is only a single direct description of persistence hunting by walking among Hs hunter-gatherers.
Nevertheless, walking down prey could be a viable option for hominins who did not possess the endurance-running phenotype of the proposed first persistence hunter H.erectus.
Our simulation results suggest: persistence hunting could
- select for both long-distance walking & endurance running,
- contribute to the evolution of locomotor endurance seen in Hs.

Kudu boy "How stupid can one be?"

Distinguish fictional endurance running-hunting from factual tracking by walking after wounded prey. MV lumps them together, and also includes rainforest net hunting and anything not done in water as "stupid".

Ever hear of the "Simulated universe" hypothesis, the one that says we're all bits of data in some giant computer? It's just God by another name.

Same thing with the "Observer" in the Copenhagen Interpretation. It's just
God by another name.

And what you offer now is just savanna idiocy by another name. It's
replacing running with walking, hunting with "hunting down" wounded
prey...

It's not science.

Yes, it's so incredibly stupid:
flat feet, naked skin, fat belly, salt sweat, and then running or even walking after antelopes...
:-DDDDD

What astonishes me most: how stupid can "scientists" be?

Human waterside evolution is 100 % proven,
only some self-declared anthropologists don't see it...

Like manatees, dolphins, seals, penguins :DDD!!

, and then running or even walking after antelopes...

Done by 10s of millions of Homo today, but include deer, moose, elk, bison, goats, sheep, cattle. MV remains like a child, knows nothing about Homo, just kudu.

:-DDDDD

The usual anti-science pseudoscience nonsense...

:-) Yes:
- cursorial mammals run on their hooves or toes, that's why humans are so slow, - humans outside the water have to protect themselves by clothes
