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 i six a

00:23

it's a long one Hi Five no sorry Yeah Okay

00:33

We're done skimming The main purpose of presenting hamilton's rule

00:36

is described in passage One is tio What And hear

00:40

the potential answers illustrate show one of five ug rules

00:45

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

00:48

keep us from being able to text in class or

00:50

skateboard on private property or ah either soup with a

00:53

fork It says chunky on the can I mean come

00:56

on And now there's this hamilton guy with the rule

00:58

of his own Fortunately rules of a mathematical nature don't

01:01

harsh our buzz all that much eh Milton's rule according

01:05

to the passage says that our times b is greater

01:08

than c where are is the genetic proximity of the

01:12

relationship between the giver and the recipient B is the

01:16

benefit for the recipient And c is the cost that

01:19

the giver incurs In other words as long as two

01:22

parties air close enough and the benefit for the recipient

01:25

is high enough to offset the downside our cost of

01:28

that relationship all the conditions are right for altruism or

01:32

selflessness to occur Shame that we need a mathematical formula

01:36

to explain why one being might show kindness to another

01:39

but hey it is what it is now on to

01:41

our answer choices is the purpose for bringing up hamilton's

01:45

rule to a illustrate why altruism is rare in the

01:48

animal world Not really It might have been unexpected but

01:52

there's no evidence in the passage to support the idea

01:54

that it's rare apparently altruism is all the rage So

01:58

we can nix choice eh Is it be to show

02:01

why vampire bats only help bats that are in close

02:04

proximity Well it's the word bloom lee that sticks in

02:07

our cross here according to the passage vampire bats are

02:10

more likely to lend a helping wing to those nearby

02:14

but they won't exclusively help out their neighbors it's just

02:17

easier to help out the close ones especially if they're

02:20

feeling sluggish after a big satisfying meal of the day

02:23

Well blood it's their equivalent of thanksgiving dinner after chowing

02:27

down on a bunch of hemoglobin all they want to

02:29

do is cling to the ceiling and watch some football

02:33

we're going to get rid of be okay then how

02:35

about d is hamilton's rule brought up to present a

02:37

theory that differs from the passenger's Main point No way

02:40

jose It does nothing but support the main point Aii

02:44

that the conditions for altruism and nature can indeed exist

02:48

You believe otherwise is a bit batty so it can't

02:51

be d which leaves us option c to quantify certain

02:54

animal behaviors right it's about assigning actual data to some

02:59

unusual relationships to explain scientifically why some creatures seems so

03:04

buddy buddy with one another We still think it might

03:06

be a kind of keep your friends close and your

03:09

enemies closer Sort of deal like it's Awesome that those

03:12

vampire bats helped us move last weekend But we don't

03:15

particularly care for the way they've been eyeing our neck
