taebae hey army😂😂

[@Joshuarichardkirby]

Na that shit is so confusing

[@nataliedevenbeck6726]

Makes it quick and simple 👍And examples make it understandable. Thanks!

Lemme help y'all out: Natural selection is: the gradual process by which heritable traits become either more or less common in a population because pressures from the environment Directional Selection is: when individuals that display a more extreme form of a trait have a greater fitness than individuals with average form of the trait. Stabilizing Selection is: when the individuals with the average form of a trait have the highest fitness. Disruptive Selection is : when individuals with either extreme variations of a trait have greater fitness than individuals with the average form of the trait. Your welcome

thanks!

[@kennorcott7074]

thank you

[@SH-bt3rw]

I'm confused, what's the difference between directional and disruptive selection?

[@savannahmcknelly7729]

I like how you know all that but can't spell "you're" right bahahaha

[@garrysingh1924]

So Bio exam ??

[@hritviktripathi8434]

Yep

[@jobedahsultanamim]

Wow, very helpful. u just told the whole thing in just 2 minutes !!

[@pramodmaurya6224]

Excellent explanation and easiest one.. thanks.😇😇😇😇😇

[@eric1172]

It is important to also understand that you need three requirements in order for natural selection to occur: 1) Phenotypic variation: Without variation natural selection can't "select" different phenotypic values, and therefore the population cannot change. 2) Non-random association between phenotypic value (individual phenotype) and fitness (capacity of survival). If there isn't a force (like the ones she mentioned) pushing for one phenotypic value to have higher fitness, evolution by NS will not occur, this is also known as "selection". 3) Heritability: If the phenotypic value cannot be heritable, then the gene cannot be passed to the next generation, and evolution by NS cannot occur.

[@andersnelson6464]

The intro song is a BOP lmao

[@daaragoodluck]

rightttt

[@lorenzoemanueletomasello215]

[@atl4476]

Great video 👍

[@efjay3183]

Great teaching and great examples!

[@beckwilde]

very clear cut and informative video! Glad I found out about your channel!

[@ignacio_the_coralbiologist]

Great video! Really explained these concepts well.

[@nurpertin521]

Short but effective...to th point..thank you

[@malna1789]

An amazing video. But the theme song is a bit loud 😂

[@jacksongraham3490]

so straightforward it helped a lot

[@anishtiwari1121]

I like the starting tune.

[@alevelsdemystified3410]

So basically in stabilizing selection,the mean of the population remains unchanged,we just have more individual that express the mean trait.Whereas in directional selection the mean is shifted in the opposite direction from the trait that is selected against.And in disruptive selection,we end up with 2 means with a trough in between,on either side of where the mean would have been had the distribution been normal(like in stabilizing selection).

[@ulanity7517]

Thank you so much for this video 😃 Would be very helpful for my bio test👍

[@bharat8627]

Very well explained. Loved it

[@heathen0001]

Thank you for this

[@angelinabon5231]

Omg this was so helpful thank you!!

[@sarahwendler1331]

Teaching me everything my bio teacher doesn’t thank you 😭

[@astha_yadav]

Omg thanks for the examples ✿

[@vaishnaviramakrishna265]

Beautifully explained

[@samjones7336]

This helped me so much! Thank you for uploading this!

very informative thanks!

[@mg-fi7em]

thank you!!! this is so helpful :)

[@evanwilson5055]

The stuff people categorize is crazy.

[@kaydengraham7556]

I have never felt this amount of rage until I had the wonderful idea of trying to understand bio

[@e-socke1935]

Good stuff!

[@chitra_7269]

this helped a lot ... thanks 😃

damn the intro though

[@almostmybedtime]

lmao ikr

[@almostmybedtime]

lmao ikr

[@gopirongali3425]

Telugu lo pettandi

[@kiinrez249]

Bruh I had no idea what the teacher was talking about, but when I came here I understood. Thank you Teacher pet (Btw "Teachers pet" sounds like an insult tbh)

[@jackcamp6231]

Boom. There it is

[@neelukonkimalla9075]

omg thank you!!!

[@saml2941]

Please can you answer my question. What is the difference between stabilizing selection and disruptive selection. Because the way you and my teacher explained it sound the same. . . . . I might have an idea the difference please let me know if I'm correct. So stabilizing favors the popular traits in a population and disruptive favors the rare and popular traits in a population but not the average. . Please reply with an answer if i'm correct because I don't want to confused Thank You.

[@MonkeyDLuffy-xr4fl]

Thanks! :)

[@devorahi]

shhh

[@abinashsethi1775]

Thanks for this

[@orianahernandez9465]

Perfect

[@jonathanaugustin647]

Right on!

This is great

[@rgbvibe]

Very concise and helpful!

[@yeah_science_]

great name for the channel though...

[@arumanosenpai7939]

thx....much help🥰

[@FrancisN155]

Awesome intro :D

[@013DREC]

Excellent

[@UndulatingOlive]

If you had an organism that could have its genetics changed at will by an outside force, say a mad scientist, but at the cost of not being able to reproduce, only rebuilt, starting as something akin to a single cell, what selection factors would still affect the organism? The need for energy The need to move to the energy source The need to notice changes in its environmental ... And are these called "selection factors" or should I be looking for a different term? Thankyou

[@BigBrain-ks8js]

Simpler conclusion: directional selection - only one can survive Stabilizing - smallest and biggest can’t survive, only the middle can survive Disruptive - middle can’t survive, but the smallest and biggest can survive

[@mohabanwar7711]

I like the intro ;)

[@nullharfe5141]

[@hennywilliamson6813]

sooo...what happens to the chinook salmon males? are they either super large or super small or both???

[@aphroditepantheon5984]

+Henny Williamson Basically as a result of disruptive selection you are expected to find either very large or very small chinook salmon males, no intermediate ones, so yeah both I guess.

[@pauladrewes8545]

both. The small and big fish will be the most common and have a larger frequency. Maybe after many many years, the medium sized fish will completely die out

[@senpaislick]

Very helpful :)

[@nolanmoney2]

what does the green line represent?

[@fernandabahena9414]

Thanks

[@Turbon]

I need to know that beginning song

[@Starn11]

good video

Helpful

[@MohdSuleman-vs7uv]

Fine as fuck

[@futchannel9190]

noice

[@veerp214]

her voice is kinda asmr

[@Jordan-wd7vv]

lit intro

[@LNRUPN]

Totally nit-picky of a comment, but you can break Hardy Weinberg Equilibrium without Natural selection occurring (ex. migration, genetic drift, etc.)

[@dominantshxrk4649]

👏👏

[@Emily-wc6tz]

This was really great but I don't really understand the difference between directional and disruptive, they are so similar. Sorry I'm not very smart

[@Emily-wc6tz]

Nevermind I get it they are just very similar

I'm doing this for 8th-grade science, anyone else?

[@lisanham7508]

Seems like bio 11 also learns the same thing

[@Wires747]

thanks for a straight forward ass video. no need for a bunch of extra bs that doesn't get to the point.

[@ricks7469]

I appreciate that you are trying to educate people about the process of natural selection. However, I'm afraid that the distinctions you are making are artificial and actually superimpose unnecessary complexity on to the otherwise sublimely simple principle of natural selection. There is only one type of natural selection. The consequences of the principle of natural selection produces populations that exhibit different types of EVOLUTION.

[@yooohow7900]

2 mins lecture gave me the "concept". But i was watching a 2 hour lecture of natural selection gave me nothing just a bunch of datas!

[@naydelinello899]

ahaha.....so no kiss ?

[@abdulrahmanalblooshi9831]

I understand nothing
