Helped pretty nicely, but i still have a question (that probably won't get answered but whatever) A question on my homework is what characteristics separates rabbits and primates from crocodiles. I don't really understand that well. My educated guess is hair, since the red line with hair is set on that branching off line and doesn't hit the other ones.
This really helped but I still have notes 😧 to write I kinda wish that we didn't have to right the notes . It would be great if I could just draw the diagram 🦄
rabbits are not rodents. they are lagomorphs. the screen says "rodents and rabbits" meaning they are two different things, which is accurate. he said "rodents, such as rabbits and mice," implying they are both rodents, but mice are rodents and rabbits are not. :)
1.) In this exact cladogram, are amphibians equally related to primates and birds. If so, why or why not? 2.) Are amphibians more related to primates than ray finned fish, and if so, why or why not?
can a cladogram tell if a species is homologous or analogous or it it not possible to tell? I mean i do see the traits they share just don't know if it was from their common ancestors or from environmental changes
Its 5 in the morning, I have my final in three hours and this is really the best video I could find on this topic, considering that I am from Germany and THERE IS NOT A SINGLE FUCKING VIDEO IN MY LANGUAGE ABOUT THIS
So how do you know which is closer related when you compare the tuna to the shark and frog? is the frog more closely related? or how do i know which is more closely related when looking at the ancestry betwen birds and sharks, and tuna and sharks...?
You have to look at their homologs. The hallmarks of determining homologs are: 1. Same basic structure/pattern (ex. humerus, radius, ulna, etc.) 2. Same embryology (ex. pharyngeal pouches, post-anal tails etc. in embryos) 3. Same relationships to adjacent structures (ex. human hair vs spider hair) 4. Same composition - Chemical makeup (ex. insect leg is an exoskeleton and is made up of keratin, whereas vertebrates have bone (calcium phosphate). They're not compatible) Sharks are cartilaginous, fish are bony, frogs are tetrapods. Each of those characteristics are derived homologs or primitive characteristics depending on your perspective.
This isn't even a cladogram this is a phylogenetic tree... while there isn't a HUGE difference, it's a big enough one that if you want to speak on the topic you should know.
+Tori Bill are you sure? It looks like the hair trait is exclusively applied to primates and rodents since it branches off. I'm not sure though you are probably right.
here i am watching this video for my online bio class, falling asleep.
yes killua, me too :
Yasmin Lewis lmao are u having FuNNnnnN with it 😪
same
WAKE UP
Same
I learnt more from this than the textbooks.
Charlie-Gacha same😂
UA-cam is the real MVP
That just means you lack the discipline to use your textbooks. Bravo.

"Soo uh, so uhh, anyways!" And its a whole new topic ;-; hahah
this is definitely gonna help with my test thank you so much !!!
mia i hope you failed... jk

if she needs a video she deserves too fail

My teacher spends too much time explaining it in class. This man can just spend 9 minutes and I get it completely.
Thank you for making this video! It explained this much more clearly than my bio textbook
This video is awesome and teaches so much more in a much less difficult way. Amazing work, thanks for helping me!!
Studying for my Biology Praxis and this was a life saver! Thank you!
Why you did not talk about the “hair” section at all !!!!!
ikr?!
fr that was my main focus aswell
This man is a true hero!
you are a Saint bro I know this was nine years ago but its still helpful to this day thankyou so much
Agreed. And I’m a HS biology instructor
plz put 1.25x speed, you sound much better! thanks anyway tho, but we havent watched yet. will update after we watch
Thank you so much for this! This helps a lot since it's hard to understand with just reading the modules
Im doing my BS in Pakistan and this was just awesome lecture. Zoology by Miller and Harley.
Absolutely fantastic video. Helped me greatly with upcoming exam !
THANK YOU REALLY HELPED ME ON THE TEST
Thank you for this!! So helpful and I learned much faster than I would have by just reading texts

Why are these so confusing, either the way my professor taught us is what’s confusing or I just don’t comprehend how this is done
This really helped but I still have notes 😧 to write I kinda wish that we didn't have to right the notes . It would be great if I could just draw the diagram 🦄
Thank you it helped sooooooooooooooooo much
Let's face it half of use are kids doing our homework but we dont understand it 😂 come on don't be shy. Your not the only one 😂
👎
mr legit you right
I'm doing an assignment that's due tmrw 🤦♀️
r/usernamechecksout
The four limbs is a bit of a misnomer, snakes are in that clade but have no legs
I seriously hate my bio course . like what the helllll. Dying on boredom ....The video is good though , explained it better than my online course
It’s me clearly understand more of this! Thank you so so much.
thanks, โศภิษฐา ขวัญสังข์
thank you so much for this, you just saved my life I love you fr
In 2 and half hours it is our challenging Bio exam. Thanks man...
.
Cladists have the goal of finding the most parsimonious phylogeny. Parsimonious: one with the fewest evolutionary steps.
rabbits are not rodents. they are lagomorphs. the screen says "rodents and rabbits" meaning they are two different things, which is accurate. he said "rodents, such as rabbits and mice," implying they are both rodents, but mice are rodents and rabbits are not. :)
I don't mean to sound stupid but why do birds have 4 limbs?
Thanks man! this was really helpful! I like your texas accent at times too ;)
does anybody else feel like they just cant do it lol. this video makes sense but school in general.
but shark and ra-fiined have gills so will both will have same ancestor or not ?
any 2 organisms have the same ancestor
Are Birds more closely related to Rodents/Rabbits than Birds and Primates?
I hope our professor bring such this questions in the exam
Which one would be the most recent ancestor according to this diagram?
Arilertzy Gaeta birds
1.) In this exact cladogram, are amphibians equally related to primates and birds. If so, why or why not?
2.) Are amphibians more related to primates than ray finned fish, and if so, why or why not?
No1 because of four limbs
No2 because of the 4 limbs they have a closer ancestor
1.) the answer is do your own homework
2.) same answer as last
Crocodilians is the correct term and yes he used it because it is a scientific term
and fishes is the correct plural noun
Karthik K I hope your were being sarcastic because “fish” is already in the plural form.
when you talk about the same species
POV: You have a bio test tmrw
Yes.
Thank you so much for the video it help me so much!!!!
couldn’t have been explained better

preparing for the college entrance exams and this video helped me learn the untaught stuff at school! thank you so much! 💛
Good luck on your test!
*•Gacha Ice Kitty•* hey, thanks! ✨
Damn I was hella confused before this video but now it makes so much sense. Thanks!
this was a lot of help tbh 💯 thank you

Yes, wings are like arms.
Emoji bad

Thank you sooo much, thought i was gonna fail
this video is awesome the only thing i dint like is when you keep repeating yourself over and over agin but everything else is great!!
This was so helpful, thank you.
this video saved my biology grade
thankyou for uploading this! it helped so much
Thanku so much for ur help I'm getting something clearly
thank you so much it helped with my hw
Fluffy Suga Kookies armyyyy
Great explanation.
what are the features of the common ancestor then ??!
What separates rabbits/primate from the crocodile on the cladogram?
hair
Its 5 in the morning, I have my final in three hours and this is really the best video I could find on this topic, considering that I am from Germany and THERE IS NOT A SINGLE FUCKING VIDEO IN MY LANGUAGE ABOUT THIS
Omg same ... I feel like I'm lucky enough to understand this is English!!
Thank u !
so helpful thank you! i have my bio final in like an hour haha
gillian bush Lmaoo good luck
Hope it went well
how did you do
Thank you! This video helped me so much!
THANK YOU SO MUCH.
Hello student from online JMHS Biology part 2!
this video is so well done, thanks
finally makes sense, thankyou so much!!
thanks was helpful alot 😃😃
So how do you know which is closer related when you compare the tuna to the shark and frog?
is the frog more closely related?
or how do i know which is more closely related when looking at the ancestry betwen birds and sharks, and tuna and sharks...?
You have to look at their homologs. The hallmarks of determining homologs are:
1. Same basic structure/pattern (ex. humerus, radius, ulna, etc.)
2. Same embryology (ex. pharyngeal pouches, post-anal tails etc. in embryos)
3. Same relationships to adjacent structures (ex. human hair vs spider hair)
4. Same composition - Chemical makeup (ex. insect leg is an exoskeleton and is made up of keratin, whereas vertebrates have bone (calcium phosphate). They're not compatible)
Sharks are cartilaginous, fish are bony, frogs are tetrapods. Each of those characteristics are derived homologs or primitive characteristics depending on your perspective.
great video!! thanks for the explanation
I am confuse. Birds only have two limbs.
no, 4, wings are limbs
This helped a lot, thanks!
How are the organisms related?
Sorry this does not make sense. Where is Jesus on this cladogram?
lol
Lol I don't think he's evolved. Been the same since the beginning of time 😂
Thank you so much
awesome video thanks brother
And now i know what a cladogram is used for
i just wanna play monster hunter world and minecraft
Understood clearly tnx👍
Someone explain the hair part.... :(
this feels unnecessarily long
i am only here for school
Really good stuff
This isn't even a cladogram this is a phylogenetic tree... while there isn't a HUGE difference, it's a big enough one that if you want to speak on the topic you should know.
two legs and two wings-yes wings are limbs
Excellent
that helped a lot thank you
How is the rodent related to the crocodile and primate
+Tori Bill I think its the amniotic egg trait
+Christian Carpenter nah it's the hair
+Tori Bill are you sure? It looks like the hair trait is exclusively applied to primates and rodents since it branches off. I'm not sure though you are probably right.
+Christian Carpenter yea you right I double checked it thanks
thank you so much!
Thanks for the great video!
Thank you
Good stuff!
thank you!!!!!!!
Thank you. This was very helpful❤️
rabbits are lagomorphs not rodents
Learned more from here than from my teacher
Can you draw a cladogram for me using provided characteristics? I'll pay you :)
But primates and rodents doesn't lay eggs tho... The vid is wrong
Math: meet my friend... taxonomy
♥️
what about hair
Primates, rodents, and rabbits are the only organisms with hair or rather fur, that’s what he meant.
