for all students who want a summary Darwin's finches (also known as the GalΓ‘pagos 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.
π¦π¦π¦π¦π¦π¦π¦π¦π¦π¦π¦π¦π¦π¦ Here are some timestamps 2:30 for introduction to the finches. 3:20 for Galapagos island size comparison 4:55 history of finches. 5:15 for answer to number 3(aka only one species of finch came from the main island.) 7:25 1977 drought. 8:30: % of bird death/beak study. 10:00 Huge rains=smaller seeds. 11:30 species definition, geographical separation. 12:00 finches mating. 12:50 male mating. 14:00 species breeding and interbreeding. π¦π¦π¦π¦π¦π¦π¦π¦π¦π¦π¦π¦π¦π¦
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.
pretty sure 90% of us were sent here by our bio teachers because of corona
i cant find half of these science questions
Who else is here because your science teacher assigned this
Seeing all these comments, I feel compelled to confess something... πππ 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. π¦β¨ 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! π€‘β¨
rip my recommended after all these videos I have to watch
Schools still want to teach even in the end of the world
i love how people are commenting βI actually learned so muchβ like NO BECKY YOU PUT IT ON x2 SPEED
Nobody: 90% of the comments: Who's here for science homework?
Shoutout to anyone watching this for Bio 12. :DDD
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!
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 .
lol watched this video in class in 7th grade, then got assigned to watch it again in 10th grade
Thanks to Corona we can all enjoy this video together π
What is the mystery of mysteries? 2. How long did the Grants study on Galapagos island? 3. What did they study? 4. How did these islands form? 5. How many species of finches are there? 6. What did they eat? a. warbler b. woodpecker c. cactus finch d. large medium small finches 7.. Fnish this quote "Right tools for the _____________ ______________. 8. What did DNA reveal? 9. How did Grants gather data of the birds? 10. What type of science investigation is this? 11. What do we know about 5960? 12. What happened in 1977? 13. Which birds had the most trouble surviving? 14. What trait made the greatest difference in survival?
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!
thank you for uploading this video.
