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     ;)

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

@cassiegariepy2171

i cant find half of these science questions

@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.

Who else is here because your science teacher assigned this

@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.

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! 🤡✨

@charlesdarwin8708

thank you for uploading this video.

@amandaf8160

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

@balakay_lol8741

rip my recommended after all these videos I have to watch

@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!

90% of the comments: Who's here for science homework?

@vennelamallampati2075

i had to watch this for class but daaannnggg it's interesting!!

@thegoldfishking7954

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

@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!

@gaurangdandwate7268

This is amazing. So much dedication and then finally letting the whole world know. Nature we bow down.

@eysuar03

POV: you were summoned here by your science teacher- btw this was a actually a very interesting video. i really learned a lot! <3

@skyayakashi2256

Shoutout to anyone watching this for Bio 12. :DDD
