Q

how does waggle dance work

A
  1. group selection: neglect own needs in favor of group

Q

cooperative Breeding

A

most likely relatives in group
-defence
prepare/maintain living area
feed young
tit for tat

17
Q

Eusociality in animals

A

-highest level of organization of society
-independently evolved
1.individuals of more than one generation live together
2.cooperative care of young
3. division of labir

18
Q

bees eusociality

A

haplodiploid-75% gene shared
more likely to die for eachother
-not all are eusocial

19
Q

leafcutter ants eusociality

A

division of labor based on head size

20
Q

naked mole rat eusociality

A

life centers around queen and her offspirng
-queen very active
if queen dies, another female will take role, competing with others

21
Q

why has eusociality evolved?

A

kin selection may play role–> high degree of relatedness
-ecological constraints–> maintenence of burrow, defence
