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 ;)

@Lucas-yj3gr

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.

@SpongiousBird

I don't understand... Do the 500+ dislikes come from high school students? I mean, as a young adult, college student, I find this video captivating. It may not teach you a practical skill, agreed, but can't you see nature's beauty and how cool the natural selection is? -_- Makes me want to get a biology degree, buy a sailboat and go hangout there.

@saneplathreader637

pretty sure 90% of us were sent here by our bio teachers because of corona

@cassiegariepy2171

i cant find half of these science questions

@enthusiast8017

Who else is here because your science teacher assigned this

@florrrina

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! 🤡✨

@balakay_lol8741

rip my recommended after all these videos I have to watch

@thegoldfishking7954

Schools still want to teach even in the end of the world

@amandaf8160

i love how people are commenting “I actually learned so much” like NO BECKY YOU PUT IT ON x2 SPEED

@skyayakashi2256

Shoutout to anyone watching this for Bio 12. :DDD

@cactusface23

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!

@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 .

@ultearmilkojohn1145

lol watched this video in class in 7th grade, then got assigned to watch it again in 10th grade

@philsopherjay4151

Thanks to Corona we can all enjoy this video together 😉

@shelbyie

I was struggling with the concepts in statistics until I found the lessons based on the data collected about the finches. I finally started to understand the concepts. I can't thank you enough!

@charlesdarwin8708

thank you for uploading this video.
