Thank you We sneak in and here's your shmoop du

00:05

jour brought to you by altruism If you're just getting

00:07

your feet wet on the generosity department well you may

00:10

want to start with some truism all right checking the

00:14

passage We're just going to skim it because it's a

00:16

lot of paragraphs One two three or six a it's

00:23

a long one Hi Five sorry Yeah Okay We're done

00:33

skimming The main purpose of presenting hamilton's rule is described

00:37

in passage One is tio What And hear the potential

00:40

answers illustrate Show one of five ug rules They're the

00:46

worst Am i right They're the things that keep us

00:48

from being able to text in class or skateboard on

00:51

private property or ah either soup with a fork It

00:54

says chunky on the can I mean come on And

00:57

now there's this hamilton guy with the rule of his

00:59

own Fortunately rules of a mathematical nature don't harsh our

01:02

buzz all that much eh Milton's rule according to the

01:05

passage says that our times b is greater than c

01:09

where are is the genetic proximity of the relationship between

01:13

the giver and the recipient B is the benefit for

01:17

the recipient And c is the cost that the giver

01:20

incurs In other words as long as two parties air

01:23

close enough and the benefit for the recipient is high

01:26

enough to offset the downside our cost of that relationship

01:29

all the conditions are right for altruism or selflessness to

01:33

occur Shame that we need a mathematical formula to explain

01:36

why one being might show kindness to another but hey

01:40

it is what it is now on to our answer

01:42

choices is the purpose for bringing up hamilton's rule to

01:45

a illustrate why altruism is rare in the animal world

01:49

Not really It might have been unexpected but there's no

01:52

evidence in the passage to support the idea that it's

01:55

rare apparently altruism is all the rage So we can

01:59

nix choice eh Is it be to show why vampire

02:02

bats only help bats that are in close proximity Well

02:05

it's the word lonely that sticks are cross here according

02:09

to the passage vampire bats are more likely to lend

02:12

a helping wing to those nearby but they won't exclusively

02:16

help out their neighbors it's just easier to help out

02:18

the close ones especially if they're feeling sluggish after a

02:21

big satisfying meal of the day Well blood it's their

02:25

equivalent of thanksgiving dinner after chowing down on a bunch

02:28

of hemoglobin all they want to do is cling to

02:30

the ceiling and watch some football we're going to get

02:33

rid of be okay then how about d is hamilton's

02:36

rule brought up to present a theory that differs from

02:38

the passenger's main point No way jose it does nothing

02:42

but support the main point Aii that the conditions for

02:45

altruism and nature can indeed exist You believe otherwise is

02:49

a bit batty so it can't be d which leaves

02:52

us option c to quantify certain animal behaviors right it's

02:57

about assigning actual data to some unusual relationships to explain

03:01

scientifically why some creatures seems so buddy buddy with one

03:05

another We still think it might be a kind of

03:07

keep your friends close and your enemies closer Sort of

03:10

deal like it's Awesome that those vampire bats helped us

03:13

move last weekend But we don't particularly care for the 00:03:16.375 --> [endTime] way they've been eyeing our neck
