Natural Selection and the Rock Pocket Mouse - HHMI BioInteractive Video
Вставка
- Опубліковано 11 вер 2024
- How quickly can natural selection work? "The Making of the Fittest: Natural Selection and Adaptation" tells the story of a living example of Darwin's process of natural selection and shows how quickly a trait can spread through a population when natural selective pressure is strong.
The rock pocket mouse shows how different genetic changes can lead to the same adaptation - a coat color that hides the rock pocket mice from predators, such as owls. Explore a classic case study in natural selection and evolution with your science students.

anyone else watching for their natural selection assignment for online school
Yup
Yes. You got the answers?
Critical Gamers INC. yooooo😂
...yeah lol
Lmao bruh I got this thing do Saturday
I gotcha guys,
Why are some mice light colored and some mice dark-colored?
- The light-colored mice were the first to arrive, but due to a mutation, dark-colored mice started to appear. Because they're more easily hidden, they were able to outlive the light-colored mice and continue to produce more dark-colored ones.
Does fur color provide any selective advantage or disadvantage?
- Disadvantage: Brighter color furs that don't blend into their environment are easier for prey to spot.
- Advantage: Furs that blend into their environment can hide from their prey easier.
What role does the rock pocket mouse play in the desert food web?
- Prey for other animals that introduce natural selection.
EDIT: Looks like there is another work spread that is attached to this forsaken video,
How would biologists explain how the mice on the lava flow evolved black fur? Include all the elements you think are needed for a full explanation.
- Natural Selection. In the lava flow environment the mice with black fur blend in better, concealing them from the predator's eyes. The tan mice, however, don’t blend in. Because the predators are visual hunters, the tan mice will be spotted more frequently amongst the lava flow and eaten. This will give the black fur mice the opportunity to make more offspring than the tan mice.
Would biologists say that the mice changed because they wanted or needed to change? Why or why not?
- Because the tan mice were being eliminated against the dark environment of the lava flow. Random mutations happen, and if they’re good (like the black fur) they will eventually evolve into a norm of the population.
Feel free to correct me on any of these and I'll edit/change/add them.

i owe you my life
THANK YOU!!!!
i love you
Omg tyyy!
I know we all have to be here for various biology classes, but kudos to the creators of this video for being able to give a great example of genetic mutations and natural selection within a succinct 10 minute video. It's really easy to see the differences between the wildtype mice and the mutated mice along with their respective living environments and how natural selection seemingly affected the rate of mutation!
Not all.

Hi Mary
yup
I’m happy to watch a video for a science class that actually has good production value and is fairly interesting
nerd lol
ight it's cool and all how we're all watching this for bio but are we all just gonna ignore the fact that this guy keeps dead mice in a drawer in his office
that's science babeyyyy
Awabhabebsd;a;lsls but it's for sci-ence!
Appreciation alert: This documentary is very impressive and the way they explain every single detail is really stunning especially the visual delivery.
Glad you enjoyed it!
TLDW (too long didn't watch):
- Light colored mice live on light colored rocks. A few of them mutated to have darker fur.
- This helped them survive on the darker rocks because they were less visible to predators.
- Over time, natural selection caused the mice on dark rocks to be mostly dark-colored, because predators were more likely to spot and eat the light colored mice in that area.
- The darker mice survived and bred, increasing the ratio of dark to light mice.
- There are more light colored mice on light rocks for the same reason.
- Mutation is random (the mice just happened to turn out darker), but natural selection is not (they had a higher survival rate if they lived on dark rocks).
- Two groups of mice had different genetics that caused the dark mutation, but natural selection had the same process of killing off the ones that stand out.
- The fact that something has a mutation isn't good or bad; it's neutral.
- The effects of mutations can be good, bad, or neutral. For example, missing a limb is generally a disadvantage, but that doesn't mean that all mutations are bad.
I wouldn't recommend skipping the video; these are just some simple notes to help you out. Also, set it to 1.25x speed to save you some time. :)
Good luck with your assignments guys!
Nice notes, the info is on point to me. Also, I had something I was thinking about. The video mentioned that if, for example, the trait of dark colored fur gave a 1% advantage, and you started with 1% of the population being dark, then it'd take about 1000 years for about 95% of the population of mice to have dark fur. What I wonder is if this considers the fact that the light-furred mice will be killed on much more regular intervals than the dark-furred mice. And also, perhaps the light colored mice will, over time, "migrate" into the lighter terrain if they're smart enough to not stick around the dark ground. That could mean natural selection (well mutations in particular) could've played much less of a role than was expressed. I'm not saying I don't believe the information presented by any means, it's just that other factors may influence the changes, looking beyond the math at face value; you can almost never take *everything* into consideration with a given calculation (you can get pretty dang close though with some things though). I just thought it's an interesting idea, lol.
get this to top 🙏🏽🙏🏽
You're a real one!
your the g.o.a.t

I love this comment section. It's the best.
I would not be watching this if we didn’t have online school😂
for some reason i was done filling out my questions like 4 mins in but finished the video
Idk who needs these answers, but this was my worksheet for science
1. How did the trait of dark fur first appear in the population of rock pocket mice?
Through a mutation in the mice’s genes.
2. Why does the dark-fur trait spread so quickly in mice that are on the lava flow?
The light-colored mice were the first to arrive, but due to a mutation, dark-colored mice started to appear. Because they're more easily hidden, they were able to outlive the light-colored mice and continue to produce more dark-colored ones.
3. Do mice that live on the lava flow actively choose to adapt to that environment? Explain.
No. Mutations are random, and this specific mutation just happened to be helpful. Natural selection slowly started to eliminate the light colored mice that are more easily seen by predators, and the population of dark-colored mice grew.
4. Consider the following statement: “Mutations are random, natural selection is not.” What does that statement mean?
Mutations are random, and won't happen to all mice, but natural selection causes the mice that are lighter colors to die off more quickly than those that are dark colored. The light colored mice are more easily spotted by predators. The dark colored mice were able to outlive the light colored mice and continue to produce more dark-colored ones.
this was very helpful!

So the rock pocket mouse is a living snickers
+Tobias Edwards Nah more like TWIX
+Adrian Flores then why did they say it was the snickers bar
+Tobias Edwards because their comparing something humans eat on the daily to something predators eat on the daily. Which is mice the "snickers" and the predators the "humans".

It's fun how my biology teacher not only has skipped our last 5 classes, but when he actually arrives to the Online Meeting, he does so only to give us this link and a series of questions before disappearing once again.
Damn I really got a quiz on this tomorrow

Mice eat cheese. Cheese was invented by humans. Therefore, there's no way mice could have existed before humans.
So much for the theory of evolution
DriveCS Who ever said the mouse came before the human?
I don't know and why are you here
Fun fact Mice do not like cheese they prefer seeds, peanuts, and bacon.

NANI!?
Outstanding work, super clearly explained. Very impressive.
I watched this as a lay person and as an older adult in order to understand how beneficial mutations could spread in a population. I once worked as an educator myself and really appreciate how clearly these professionals explained natural selection and the spread of beneficial mutations within a population. Kudos for brilliant work!
Prof. Nachman is a teacher of mine, and he is still as passionate today about pocket mice as he is in this video (he regularly brings us samples of them). Really enjoyed the content!
Aye for anyone watching this, if you have questions to answer on it or an edpuzzle, open the transcript of the video and then control+f on a laptop and then search for keywords in the question. Makes work so much easier.
omg thanks

Like I really don't know what y'all are on about here.

"These mice are the Snickers bar of the desert."

This is a great video, thank you for uploading this. It is the most simple and to-the-point explanation of natural selection there is, I use this every year with my class when teaching NS. Cheers!
Glad it was helpful!
Small error from the narrator at 2:35 : It says "the mice here have evolved". Individuals do not evolve. Individual mice didn't suddenly decide to grow dark hair. Rather, in the lava-filled areas, the predators eliminated the mice with light colored fur. Over time, the surviving mice (mostly those with the dark fur mutation) reproduced and the population evolved to become darker in areas where being darker was an advantage!
I believe that here they referring to "the mice" not as individuals but as the population.

Explain how you decided which illustration represents the most recent rock pocket mouse population and why you positioned the others in the sequence as you did. Refer to figure W,X,Y,Z
Any reasonable explanation is acceptable. Students might comment on the fact that the number of light-colored mice has decreased over time, while the number of dark-colored mice has increased.
1. Explain why a rock pocket mouse’s color influences its overall fitness. Remember that “fitness” is defined by an organism’s ability to survive and produce offspring.
An ideal coat color like that of a rock pocket mouse will help it to camouflage with rocks and hence help it to escape from predators.
2. Explain the presence of dark-colored mice at location A. Why didn’t this phenotype become more common in the population?
it did not afford a selective advantage to the mice.
3. Write a scientific summary that describes changes in the rock pocket mouse populations at location B. Your summary should include
• a description of how the population has changed over time,
• an explanation of what caused the changes, and
• a prediction that describes what the population will look like 100 years in the future. Base your prediction on trends in the data you have organized. You can assume that environmental conditions do not change over the next 100 years.
Originally, location B had a sandy-colored soil. Light-colored mice had a selective advantage because
they could better avoid predation.
Location B became covered in dark-colored volcanic rock, which means that dark-colored mice now had an
advantage over light-colored mice in that environment.
Over time, dark-colored mice became more common at location B because more of their offspring survived to reproduce and pass on their genes, including the gene for fur color.
4. Use the data and what you have learned about evolution to explain how mutation is a random process, but natural selection is not random.
The mutation which results in a dark colour coat was present in the population before any volcanic activity could result in a dark soil, indicating that the mutation is random. However, the dark-colored phenotype became more common once there was a selective advantage for it, which indicates that selection is not random.
I know were all here because of online school and are forced to watch it but this is actually really interesting
The only one smalle error is that someone said that mutations are rare events. Mutations are common, everyone has more than a hundred novel mutations at the start of conception.
Meaningful mutations are rare. Most mutations are useless.
he meant mutations to a specific gene are rare, not mutations in general. Kind of how dying isnt rare but a 12 yr old dying on feb 5th is relatively anyway.
ha! nerd, talking about science like it really matters.
silent mutations happen all the time. it is very rare that a genetic mutation will actually change the amino acid makeup of a protein.

summary of some bio stuff
Mutations occur randomly, and the environment does not affect them (directly).
The environment DOES affect which individuals survive and produce offspring.
SOME mutations can be beneficial in an environment, resulting in more offspring with the mutations, and a higher overall frequency of that mutation occurring.
Different mutations can produce a similar physical effect.
Beneficial mutations will spread faster if the reproductive rate is very high (such as in mice)
yo I missed it in the video, does anybody know what role the rock pocket mouse plays in the desert food web?
Snickers
@@biointeractive oh thank you
Thankyou for giving me two things: 1) I truck thru NM and always thought the lava looked recent.
2) Speciation can happen very rapidly under simple altered conditions and extreme predation pressure.
Both 1000 years - so new. 🚛🔥💨
A couple more things: -
A) Random mutations are not 'copying errors' - they are an engine of creation.
B) Obviously the black mice from different lava flows are a very simple example of 'convergent evolution'. Let's hope they don't all turn into crabs too.

Despite their name, pocket mice are not mice at all, they are members of the family Heteromyidae, which also includes the kangaroo rats and kangaroo mice, additionally heteromyids are the smallest rodents belonging to the suborder Sciuromorpha, meaning pocket mice are also more closely related to squirrels, beavers, and gophers than they are to mice, pocket mice only superficially resemble mice due to convergent evolution.
Can anyone tell me if this is stabilizing, directional or disruptive selection? Pls
Its directional
