If you need a long summary, here you go: (also i recommend watching at either 1.25 or 1.5 speed) The video is about the Galapagos Islands, and how the finches that live there have evolved. Two scientists, Rosemary and Peter Grant, have come to the Galapagos every summer since 1973 to learn more about the evolution of finches on the islands. In the video, they talk about a wide variety of facts, not just about the finches. An example of this is the history of the Galapagos, how they rose about 5 million years ago (relatively young for an island), are about 600 miles off of mainland Ecuador, and were discovered by Charles Darwin on his journey around South America. They talk about how the first finches had a small beak perfect for finding small bugs on plants, and they slowly evolved to how they are now, with a thicker beak designed for getting fruits from trees. They also talk about how all of the over 13 species of finches are related to each other in some way, which tells that only one species came from the mainland and the rest evolved over time. The video talks about the history of the finch, and how the scientists would catch, measure, and tag the birds every morning in the hopes of discovering more about the birds. In 1977, a horrible drought came to the Galapagos, and almost all vegetation disappeared. The ground finches were competing for food. They eventually had to turn to the larger nuts, where the smaller-beaked finches had problems. Over 80% of the ground finches died that year, where there was no rain for about 18 months. Because of this, the finches evolved to have larger beaks. 5 years later, there was about 10 times the usual rain amount. This changed the island so much that when the drought came again a few years later, the seeds had actually decreased in size. The Grants also discovered that the different species of finch would not mate. They also had different sounds, and males would only mate with females who had the appearance of their own species. The video ends by explaining that around 2 million years ago, one finch population arrived. When its offspring went to the other islands, they faced different conditions and had to evolve to meet those conditions. yes its spell checked, yw ;)

for all students who want a summary Darwin's finches (also known as the Galápagos finches) are a group of about 15 species of passerine birds. They are well known for their remarkable diversity in beak form and function.This is because of natural selection.They used to be 1 species but as they moved from the different islands ( different environments) they adapted and became many species.

[@ariananikki9836]

[@GuyWhoPlaysWarhammer]

Darwin’s finches are a group of about 15 species of passerine birds. Well known for their remarkable diversity in beak form and function, they were first studied by Charles Darwin and have now been studied for 40 years by Rosemary and Peter Grant. Each beak possessed by each finch has a beak made for a specific job and diet. When looking at the evidence, we can determine that 1 finch arrived on the island and evolved into 15 different species. To prove this, there were 2 instances of evolution on the island. In 1977, there was a large drought and small seeds, the food that ground finches with small or medium size beaks eat, became scarce. 80% of medium ground finches died but the survivors evolved slightly to have larger beaks so that they can eat the larger seeds. The other instance of evolution was in 1983, when an El Nińo brought 10 times more rain than normal, causing vines to grow everywhere. These vines covered even the cactuses. Two years later, there was a drought and the large seeds that large seeds that the large finches eat became scarce. However, the small seeds were in abundance because of the vines. The large finches then evolved to have smaller beaks to eat the seeds. When testing what separates the species of finches, the Grants determined that song and appearance was what separated them.

Seeing all these comments, I feel compelled to confess something... 👁👄👁 Back when I was still in school, my IB Biology (HL) professor asked us to watch this sometime during Year 1 of IBDP (so most probably 2016), and I just added it to my Watch Later, never actually watching it. When it was brought up in class next time, we all pretended we had watched it, and while I am not sure if the professor bought our act or not, that was that. The video was never mentioned again. This was the actually the very first video that I ever added to my Watch Later. I had never used the feature before this, surprisingly. I could not get myself to remove this from the list, so every time that I sort it from Date Added (Oldest), this pops up on top. It is 2020, and I am in university right now. Seeing all these comments about professors directing everyone to this video makes me feel oddly nostalgic. I almost hate to say it, but I miss the IB, despite how demanding of a programme it was. I miss the school, and I miss nearly everything about the experience. It is hard for me to accept and believe that I am not a current IB student anymore. Damn. I hope I feel better once I post this comment. This was a long time coming... Try to enjoy school while you can, my dudes. 🦋✨ P.S. I am finally going to watch this thing, lmfaooo. Over three years late, yes, but at least you cannot say that I never got around to doing it! 🤡✨

Thanks to Peter and Rosemary Grant they have documented and witnessed evolution in progress. With enough environmental pressures evolution kicks in high gear resulting to the birth to a new species. Beautifully done video!

[@moransinaction]

Its a suspected cause of evolution, which highly supports the idea of it. It certainly makes sense that over a long period of time, if natural selection keeps occurring, that a diversification of species could indeed occur. While natural selection does not equal evolution, its just so much of a strong indicator that evolution is real that I could honestly not see how it isn't. I do have one more thing to add though. Epigenetics has recently supported the Lamarckian idea of evolution, in which traits that are acquired can be passed down genetically. Of course this only refers to specific marks that occur in the DNA on a very molecular level. Its truly fascinating. I know because evolution is called a "theory," its often times dismissed as something that has not been proven, and while that is true in a sense since nothing aside from mathematical ideas can be truly proven in a sense ( for example, can you prove that everyone is truly real aside from yourself? how do you know you're not in the matrix or something), a theory is actually something that is backed up with so much evidence that its very hard to falsify and nothing has falsified it yet, but it is widely accepted as truth, similar to the theory of gravity. I know you didn't that you didn't believe in evolution, but I did want to share this in case you did not.

[@geobla6600]

Thank goodness for the devotion , discipline and the incredible zealousness shown by these two Evolutionary Biologists who have spent their combined entire scientific careers of 80 years showing how adaptive radiation or simply variations that take place within a species that may or may not be an advantage in that variation . Not a lot to show for 2 or 3 million years of evolution , 13 distinct FINCHES from a finch and not an albatross. So what farmers and animal breeders have known for millennium and have utilized these same recognizable genetic variables to much greater effect in sometimes as little as decade , and yet we have highly educated people still postulating these incredibly merit-less and lacking claims 150 years latter .

What I learned about the many species about the finches are how each one is diverse and is specialized to do one thing. Like with the beaks certain types of finches hunt and feed on for example Larvae and or cactus plants. Each Finch looks alike but has so many different characteristics that make them all so unique. One thing that really is strange is why there are 13 different finch species that all evolved and survived on the Galapagos Islands. - There you go thank me later, now go get ready for history Tomorrow

Overall, the Finches of the Galapagos became different species since when the populations geographically separate and adjust to their new habitat/environment, they undergo adaptations. When or if they come back in contact again, they won’t mate. Hence, creating distinct species.

[@zayaanhussain8096]

if anyone is here for class, here are some Q/A that I had. 1. How many ancestral species from South America got to the Galapagos islands and evolved into the 13 species of finches that exist there today? What evidence supports your answer? There is said to be only one, this is said because they have more in common with each other than they do with the same genus on the mainland, which makes us believe they all ended up evolving from 1 species of bird. 2. On a small island (Daphne Major) that had a few good years, an 18 month long drought that began in 1977 affected the medium ground finches. What percent of medium ground finches died that year? Why were so many finches dying and what characteristic was more common in surviving medium ground finches than in the ones that died? The birds with the smaller beaks had the most amount of trouble because they could not eat the larger seed while the birds with the larger beaks were able to eat the larger seeds. About 80% of the medium ground finches died. 3. How did the next generation of ground finches change from the previous generation? Why did this happen? The next generation had about a 4 percent change in their beak depth. Their beaks got even bigger since the surviving ones mated, making their bigger beak genes combine and giving their offspring big beaks as well. This is due to natural selection. 4. In 1983 a strong El Nino climate event brought much more rain than usual to Daphne Major island. Then the drought returned 2 years later, but the seeds left by the dying plants were different from the drought in 1977 because the dominant plant species that grew before that drought were different from the plant species that dominated before drought after the 1983 rainy spell. How were the seeds of the dominant plants different than before and how did that affect beak size in surviving ground finches during the drought 2years later? The seeds which were larger became more and more scarce, while the smaller seeds were more available. The birds with larger beaks had trouble picking up the smaller seeds produced by the vines. This affected beak sizes by making them smaller since they were the ones who survived. This is due to natural selection, once again since the birds with bigger beaks died out. 5. Which 2 characteristics keep the different finch species from interbreeding with each other, thus helping to keep the species separate from each other? One of the characteristics is that they all sing different songs, which helps them differentiate from each other. They are also able to differentiate via the looks of the other species in the sense that the cactus finch would only pay attention to birds that looked like them and their species, and pay attention to no other birds. They were able to differentiate via beak size and body size. This is how they were able to stop from mating with each other.

Best video of evolution😉😇

[@KARAIsaku]

The variation in the beak size and form and other aspects of the Galapagos Finches, is epigenetic variation and adaptation. The epigenetic system works “above” the basic genetic code governing how it is expressed and fine-tuned in accordance with environmental impulses. However, it has nothing to do with the Neo-Darwinian model based on random mutations in the DNA. It is safe to say that much of what has been and still is interpreted as evolution that has needed millions of years of trial and error to happen, is much better explained by these adaptational changes due to epigenetic tuning.

X-ray astrophysics student that on the side reads every two weeks one book on Evolutionary theory...today I'm starting Jonathan Weiner's " The Beak of the Finch "...so here I am getting visuals for the book.

Anyone else watching this because your teacher assigned it and it’s supposed to help you with your science test?

[@calebsheffield7881]

i am

The population of birds with bigger beaks increased their survival throught the drought. Finches went through divergent evolution in order to survive. The average before the drough was aroung 9mm and after the drough it increased to around 9.5mm. Their offspring had a 4% increase in beak size. From 9.3 to 10.3mm there was an increase of bird survival

why at the end of the world do i have to watch a 16 minute video about birds (idek what its about)

[@rohimabegum7734]

La vidéo est vraiment bien faite et est très intéressante

[@MsJiroah]

While watching this video, a bird started singing outside my window that sounded a lot like the cactus finch. haha

[@knucle7683]

BridgieBee wow while reading your comment a bird just sing outside my window.

According to the film, how many species of finches arrived on the archipelago?

[@Euzcom_Clone]

99.9% of people are here because of science homework, right? My homework paper is just called Galapagos Finch 💀👆

we're really all living the same lifes out here, doing our science hw and such
