The endurance running hypothesis and hunting and scavenging …

This causes problems for the hypothesis of persistence hunting and running to aid scavenging.

to our for endurance running hunting and scavenging

Some good points but I think persistent hunting/endurance running is a bad example.
1. Long distance runners have no ass, lifters and sprinters have a great one. Squats, lunges, and deadlift make a great butt; jogging makes a great butt disappear.
2. As Bret has taught us, the hip thrust is the best glute activation exercise. Suggesting to me that prominent glutes are the result of an upright standing and walking position. Ideal for a superior long distance view of the Desert – the other bipedalism hypothesis (along with freeing up the arms to carry, and less sun exposure in the desert sun).
3. Males are stronger no doubt, but I question whether our glute development is better than females. Pound for pound or to scale, I’m guessing the Females glutes are larger in proportion to the rest of their body. Again, questioning persistent hunting as the reason for better glute development? While the men were out hunting, the women were doing all the bending, squatting and lifting children, food, and everything else.
Just some thoughts. Totally onboard with sitting making our butts disappear. Perhaps suggesting once again that standing is a big component.

Over hundreds of generations, our ancient ancestors evolved bigger and stronger butts, butts that improved the Paleolithic man’s survival in environments where physical activities –such as hunting, digging for tubers, and scavenging for meat – were a natural part of daily life. Besides scaveging, one of the strategies our Paleolithic ancestors probably employed in the search for food was persistence hunting, a hunting strategy in which hunters use a combination of running, walking, and tracking to pursue prey to the point of exhaustion. This strategy favoured members of our genus who have a superior ability to thermoregulate compared to other animals. Persistence hunting is still used by some today, such as the !Kung and the Bushmen of Kalahari.

Although there’s some controversy surrounding the endurance running hypothesis, it’s generally accepted that running – perhaps with intermittent periods of fast walking and high intensity – is at least partially what made it possible for our Paleolithic ancestors to put food on the table. This is supported by the following facts:
