How Beavers Evolved to Build Dams

- Beavers build dams to help create a deep pond of quiet water, where they then build their home or lodge. A beaver dam is a marvel of engineering that changes the surrounding landscape. But how did this behaviour evolve? And what were the selective pressures that led to the evolution of dam building?

Years ago I spent a summer in a cottage on it's own large lake up in Northern Ontario. There was a beaver dam at one end with a pretty big lodge nearby inhabited by one enormous beaver. I spent the first days paddling around in an old wooden canoe and trying to get close to the beaver, who didn't like that at all. Lots of slapping of the water with the tail if I got too near. Then one morning I got up and walked down to the edge of the lake and saw that the canoe, which I had pulled up onto the gravelly shore, had an almost perfectly circular hole gnawed out of the bottom.
Bea-ver of beavers!
@@FrankAndrewI Too true!
That's only a warning if you ever taunt further, you're ginna wake up missing a leg 😂😂😂
what a spiteful little bugger
@@FrankAndrewI dunno if you deleted this or if this comment is no longer visible I don't care this meme is funny and appropriate pbs.twimg.com/media/FD4lnYUVQAg4Urm.jpg
Really appreciate the calm delivery and non-noisy editing, I feel like learning and new information is better received that way, you know... like in a classroom. Good work!
That’s definitely the vibe I was going for! Thanks so much for commenting!
Calm delivery? Not noisy? I envy your classrooms
Beavers are amazing creatures. Dam building alone is quite breathtaking when presented with all of the positive effects it has on the surrounding ecosystem. Marvelous.
When in their natural habitat, around here they are pests who destroy the surrounding ecosystems. Horrendous.
@@eleSDSU beaver might be good in Southeast Asia.. where rice farming is main agriculture.
The raw amount of fascinating information coupled with the narrator's soothing, calm voice is an unbelievably therapeutic combination.
Fantastic video, and how you use youtube to perfection. 8 minutes of pure, interesting information, instead of a TV program which has a specific time period. Great work here.
Dam! Beavers are so fascinating. Really good video :)
Dam yeah! Thank you
Your channel is great. Keep up the good work and I'm sure it will pay off. 👍
I hope so! Thanks for watching :)
Easy. The master builder deity gave them the power to engineer the forest : D
How does the oxygen last in the lodge? Beautiful video.
I wonder, if the lodge is just a pile of branches and logs with no mud holding it together, maybe it has good air circulation since the den is above water.
Beavers are too cool! So happy you included that they get triggered by the sound of running water lol!
Beavers will sometimes dig channels out from the pond giving safe ways to reach more trees. Their predators can't swim very well.
Small channel but big content
Keep going brother you’ll make it, I believe in you. Quality stuff
Thanks so much man!! I really hope so 🙏🏽
This is why I pay Internet
High quality content right here
Great video. I loved the content, the visuals, and the delivery. I look forward to seeing more!
2:23 Well, maybe there are more than two. Back in 1946 Canadians sent 10 beaver couples for a fauna enrichment experiment to Tierra del Fuego and they have been wreaking havoc ever since and at some point they are going to diverge from Castor Canadensis, if that hasn't already happened considering how we haven't been able to exterminate the pests.
P.s.: If you ever feel like helping nature and get yourself a nice pelt at the same time, hop on up to Tierra del Fuego and get those *dammed* beavers.
This is such a gem of a channel!
Only a couple of video by this author, but very impressive, of high quality in images & contents. That indicates considerable amount of time for research. Several notches higher than others.
Here's a thing to be addressed in future: before dam-constructing behavior was established, semi-aquatic lifestyle preceded. That may provide them with protection to a large extent. Then, what was the construction of dam for, or how did it have to occur, if it was the case? A few steps more to be filled. This series is always very successful in suggesting further thinking. Inspiring!
Excellent work
Cheers! Stay tuned for more videos
Magnificient! Also, the narator's voice is soothing
greater appreciation for beavers !!! theyre so amaaazing . thanks for the vid , vERY informative and i love the aesthetic
Really good video
Glad you enjoyed it!
Gret video! really helped me complete my project on the evolution of beavers. Keep up the great work.
why tf this channel only has 2k subs, keep the good work man
I misread the title as 'Damn... Building?"
Beavers are like construction workers of the animal kingdom
really liked the video, found it very informative, just wondering where did you get the information about the first signs that beavers began building dams 7 MA?
Glad you enjoyed the video! 🙂 I got that bit of information from Figure 8 in this reference:
Plint T, et al. Evolution of woodcutting behaviour in Early Pliocene beaver driven by consumption of woody plants. Sci Rep 2020;10:13111.
thanks for the great video bro
Beavers are cool.
Excellent informative short film.keep up the good work.👏👏👏👏👏
Human : beaver are very brillian species!
Beaver : i just cloth the river stream so I can sleep safely
What a majestic and smart animals they are, may God forgive us (humans) for what we doing for this planet 😢
Can we take a moment to appreciate the fact that this animal cuts down trees builds a dam so it can build a house that can only be entered from under water
no, we can't and I detest that phrase
yet another awesome video :) thank you
Much appreciated!
Amazing channel, you’ve got a new sub
Definitely an underrated youtuber. Great video
This channel is amazing. Wonderful narration. Well Done!
Beavers, I believe, are the only animals other than humans which can change the land so much it can be seen from space.
great video m8, keep up the good work
Cheers! Will do! I got more videos lined up so stay tuned
Exciting to watch more videos by you!!
More coming soon! 😁
So amazing..animals in general are but its sad when the 2yr olds gotta leave home n find n make there own..majority dont even make it..animals n cars ect.huge problem n threat but luckly theres plenty around!
Excellent videos. Subscribed.🎉
Just an amazing channel, tuank you.
Great explanation and I really like the Thumbnail for the Video 😃
Thanks so much! 🙂
Hey, yeah hello! How the hell did you get that camera angle INSIDE the lodge?
Wow these animals are remarkable
The most excellent vid about Beavers of all time, made by a .... G E N I U S
How did giant beavers help in prehistoric times. I bet they had some huge dams if there were beavers the size of bears. I bet there were some huge swampland areas from them too. I’ve been trying to find stuff on the prehistoric beavers but not finding much
the giant beavers didn't build dams and lost their appetite for woody plants, which might be why they went extinct since they weren't able to have food stored in a winter-proof bunker
finally, some good content
bear sized beavers would be fucking nuts i would never swim in canada again
If i were to be reborn as any animal, I'd be a beaver. They're the sigma males of the animal kingdom.
Nice beaver.
Amazing.
good video very nice
What if there was 7 billion beaver
The perfect animal
How did they use their teeth to dig?
Why they doing that
American here what the hell is a kilogram
Beavering away.
It's just a backward platypus
Have you watched ZeFrank?
im hearing voicess
WHY do you need the background "music" - it is especially annoying when the presenter is talking or natural sounds are present.
I chew up beavers the way they chew up trees
Is climate change responsible for every unexplained evolutional twist?
Any change in the environment is an answer for changes in evolution, as evolution is ultimately dependent on how well an organism is able to fit into their environment. Shifting climates is one of the biggest influences on evolution, so it's a plausible explanation, especially since the beavers lived through an ice age, which would've introduced a plethora of evolutionary pressures.

I'm sorry, but the idea that a program such as modern beavers run came into being purely by accident is impossible for me to believe. I spent many years trying to make computers do things, and one thing I learned early on is that there is no such thing as a program that almost works. You need the whole thing at once. No evolutionary approximations along the way.
Talk faster lol….
For the love of Christ compels us, because we judge thus: that if One died for all, then all died; 15 and He died for all, that those who live should live no longer for themselves, but for Him who died for them and rose again.
16 Therefore, from now on, we regard no one according to the flesh. Even though we have known Christ according to the flesh, yet now we know Him thus no longer. 17 Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new. 18 Now all things are of God, who has reconciled us to Himself through Jesus Christ, and has given us the ministry of reconciliation, 19 that is, that God was in Christ reconciling the world to Himself, not imputing their trespasses to them, and has committed to us the word of reconciliation.
20 Now then, we are ambassadors for Christ, as though God were pleading through us: we implore you on Christ’s behalf, be reconciled to God. 21 For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him. 2 Corinthians 5:14-21

To posit that this genius work may have started by coincidence or luck is another reason evolution is false. Just admit and acknowledge God created them this way for this and continue to explain the actual hard work and ingenuity they put in to get it done
Ya right beavers didn’t know how to build a dam until they evolved. Who is going to believe such a ridiculous thing. The creator of the universe God almighty designed them to build dams when he created them.
then they wouldn´t be mammals
I only discovered beavers in the last year. Remind me of their distant relatives, guinea pigs (I have 4). To then find out how useful they are, well I am rooting for the beaver, now.
I love your work! Going to watch this again, with my young boys.
Beavers 🦫 are amaziiiing 👏
Excellent informative short film,keep up the good work.👏👏👏👏👏
