Meat May Be The Reason Why Humans Live Longer Than Apes


 Meat, that's what for dinner.

Ever wonder why humans outlive apes? The answer might be because we eat a lot of meat. Genes evolved in humans to adjust to a meat-rich diet helps fight diseases associated with aging such as cancer, heart disease and dementia. Not to mention, the expansion of brain size in the genus Homo is also attributed to an increase in meat diet. Check out the MSNBC article "Meat may be the reason humans outlive apes" and the paper "Evolution of the human lifespan and diseases of aging: Roles of infection, inflammation, and nutrition" by Caleb Finch on PNAS.

I'm sorry, but I found this post misleading. saying that maybe humans outlive apes because we eat a lot of meat is wrong.

the MSNBC article states that it's human peculiar cholesterol-transporting gene (not meat) that helps fight diseases associated with aging such as cancer, heart disease and dementia. and maybe that humans evolved this gene 'to lower the risk of degenerative disease from the high-fat meat diet they consumed'.

jumping into canyons helps developing wings, but I don't think we will get a pair of wings if we start jumping into canyons.
