And here's your shmoop du jour brought to you by

00:05

scavengers they can be real pests so we recommend just giving them whatever [Scavengers at peoples feet]

00:10

there after and sending them on their way ...like the IRS all right check

00:15

out the passage....[Mumbling]

00:45

How do the naked mole-rats described in passage 2

00:48

not the ones from Kim-possible that the criteria of Hamilton's rule as described

00:54

in passage 1 and here are the potential answers... Remember Kim-Possible?

00:59

...All right well what do you know Hamilton's rule is rearing its ugly head [Horse chewing hay]

01:05

again just when we think we're out it keeps pulling us back in, Godfather 3

01:11

ask your parents... Here we're being asked to take a look at the naked [Pictures of naked mole-rats]

01:16

mole rats not too close now they'll nip your nose and apply Hamilton's rule to

01:20

their interaction and see how it applies well as a refresher Hamilton's rule is

01:25

expressed as a formula thats r times B is greater than C which basically means

01:32

that altruism among the species will be present if the relationship between the [Hamilton's formula]

01:36

members and the benefit to the community outweighs the cost, so penny pinchers are

01:42

not welcome here let's take a look at B) for starters there are no cost to

01:47

the non-breeding members well that ain't true the non-breeding members don't get [A van and car parked outside a motel]

01:51

to do what you know the fun stuff instead while the breeders are having a

01:56

grand old time the non breeders are busy building tunnels transporting food and [Trucks transporting food driving by]

02:02

so on if you ask them, there is definitely a cost all that labor, not that

02:07

they're complaining but just happy to be gainfully employed...okay then what about [Woman labor worker]

02:13

C) non-breeding members demonstrate altruism only toward their queens no

02:18

royal treatment here everyone in the colony is basically an equal even if [People stood together as equals]

02:22

some of them are doing a bit more of the heavy lifting well, we take that

02:27

back everyone's an equal except for Claude, that guys a rockstar...Okay so it

02:32

isn't C) moving on, D) the cost of some members of a colony are higher than

02:37

the cost of others well yeah certain mole rats are footing in OT but that's

02:43

only half the equation, literally look at that Hamilton's rule formula [Man working and Hamilton's rule formula appears]

02:47

again yeah this option isn't taking into account the benefits just the cost so

02:53

option D) is trying to pull the wool over your eyes you dirty mole rat old movie [Man appears shouting you dirty mole rat]

02:57

..Okay well then it's got to be A) right the

03:02

benefits of working for breeding members outweigh the costs of working that's

03:06

totally accurate and also addresses both halves of the formula of course we didn't [Wardrobe doors open and reveals Hamilton's rule]

03:11

figure all this out ourselves we just put a couple of non-breeding mole rats

03:15

to work for us here at shmoop.. those guys are so industrious [Mole-rat wearing a flat cap]
