Canine teeth? What about those ancient sharp knives, axes, spears, traps that our early human hands could make and use?

Hard to trust ANYTHING from “Scientific American” - which is neither! But this article doesn’t do much for me. It doesn’t address why some get fat and others do not.

Yes. Chimps don’t make monkey wrenches.

Errrrr....

Yeah.....

:has flash back to watching what chimps do to other monkeys:

Let's not go there any more.

Can you give a one or two sentence explanation of what the author said. I got about three sentences in and my mind went blank.

They did a true study of caloric usage vs age and found that kids have hyper metabolism (as expected due to their rapid growth), from age 20-60 everyones metabolism basically stays the same (men and women) and then metabolism drops off with body mass as people age beyond 60.

Was a suprise to me as I definitely felt like i went through a metabolic rate change in my mid-30s, but what they attribute those changes to are changes in activity behavior and diet and not to how you body actually processes the energy it receives.

Also indicates that the more active you keep yourself going the less mass you’ll lose and the more likely you are to keep your metabolic rate up...though that requires additional study to prove definitively.

Thanks. So much for my labeling efforts.

[ifinnegan]

Yes. That was like a tiny portion of this long winded rambling pseudoscientific crap.

there’s been nothing “scientific” or “american” in scientific american for several decades, so there’s no point in reading a single word they publish ...

I am not descended from apes.

Do you have any ancestors who were democrats?
