A

early decrease in size, later increase (mammals) early increase in size (birds)
decreased flight distance from people
coat and plumage color changes (this relates to behaviour) retention of neotenic characters

Q

List basic characteristics of a species that lead to ease of domestication

A

Characteristics of some wild species favor existence close to humans. Failure in any one of these usually results in no domestication.

diet: usually herbivorous or omnivorous
growth rate: the faster the better
easily reproduced in captivity (polygamy, no elaborate courtship) disposition (not too nasty or aggressive)
limited tendency to panic
social structure: herds, defined dominance pattern, overlapping
ranges rather than exclusive territories.

Q

landrace

A

isolated by default (culture/geography/communication) no standard - Feral = domestic-> free living state, will never be wild (small brain forever)

travel, less grass, less parasite

32
Q

products if cows

A
  • milk, meat, leather, draft, horns (plastic), manure, fertilizer, fuel, manure bricks, bank account and wealth symbol, bride price, sacrifice COW POX
33
Q

• Discuss the consequences of hog management and selection for production and welfare.

A

They eat trash and when they were eradicated towns smelled SCAVENGERS
With pigs gone more charcoal production,(trees removed -> landslides hurricanes

Changes!! Concave face, curly tail, lop

Fatness first then leanness (wild type) welfare bc skinny = unhappy

Bacon type= large long no muscle
Lard = cobby, fat, thick
Meat = long thick muscular

34
Q

Describe the selection pressures of animals for transport purposes.

A

Keep some wild adaptations - low repro rates for harsher landscapes Goals: Riding packing draft, meat milk
Camels replaced the wheel in egpyt Bactrian fiber occasionally.
