The Dog : our earliest friend
• Perhaps wolves followed human hunts to scavenge
The ice ages : three dog nights
• Dogs as warmers in cold nights
• Sentries in the night - good smell sense that humans lack
Small dogs : a product of farming
Innovation in hunting technology
• Impact on animals depends on technology + population size
• Population sizes become much higher in wetter habitats
• Animals not much reduced by San hunting, compared to rainfall
Rancho La Brea
• Oil pools had water on top
o A trap for animals coming to drink
o Huge numbers entombed in tar
America : advanced hunters arrived
Larger animals give birth more slowly, so when hunted, they don’t recover fast
The origins of farming : the great mistake
• Populations increased due to more food, easier hunting
• Diver technology
Climate change and agriculture
Hunting changes in fertile crescent
Prudent hunting, herding
• Natufian : began herding gazelles
Gazelles were NOT domesticated
• Have long legs
o Run fast
o Jump high
• Have long sharp horns
• Dangerous to handle
• Males are territorial when mating
Diamond's Criteria
• Flexible Diet
• Fast growth rate, mature quickly
• Breed easily in captivity
• Meek disposition
• Do not panic
• Social hierarchy
Document Summary
The dog : our earliest friend: perhaps wolves followed human hunts to scavenge. The ice ages : three dog nights: dogs as warmers in cold nights. Sentries in the night - good smell sense that humans lack. Impact on animals depends on technology + population size: population sizes become much higher in wetter habitats, animals not much reduced by san hunting, compared to rainfall. Rancho la brea: oil pools had water on top, a trap for animals coming to drink, huge numbers entombed in tar. Larger animals give birth more slowly, so when hunted, they don"t recover fast. The origins of farming : the great mistake: populations increased due to more food, easier hunting, diver technology. Prudent hunting, herding: natufian : began herding gazelles. Gazelles were not domesticated: have long legs, run fast. Jump high: have long sharp horns, dangerous to handle, males are territorial when mating.
