Lieberman: Mismatched diseases caused by recently changed interaction between genes & recently changed environment #amnhscicafe

Lieberman: Environmental causes are incremental, difficult to perceive #amnhscicafe

Lieberman: Humans evolved to be gas-guzzlers of primate world, mainly on brain (20% of metabolism) #amnhscicafe

Lieberman: Humans have a costly life-history. Hunt & gather high energy carbs & fat. #amnhscicafe

Lieberman: Agriculture gave people easy access to carbs & fat (600 generations ago) + industrial processes (10 generations) #amnhscicafe

Lieberman: Now we get lots of sugar (>100 lbs sugar/year) without much fiber -> Type 2 diabetes! #amnhscicafe

Lieberman: How treat diabetes? Exercise & diet OR medication. The former treats the cause, the latter the symptoms. Mismatch! #amnhscicafe

Lieberman: Humans evolved to be endurance athletes. Hunter-gatherers walked 9-15km/day vs 2-3km/day for chimps #amnhscicafe

Lieberman: Early industrial era sewers used 18 NYC marathons of energy/year more than a modern textile worker #amnhscicafe

Lieberman: People who are less physically active when young have less bone growth & are more probe to osteoporosis. #amnhscicafe

Lieberman: We are mal-evolved to novel environmental factors: reading -> myopia, shoes -> flat feet #amnhscicafe

Lieberman: Mechanisms for myopia...blah, blah, blah...Zonules of Zinn! #amnhscicafe
