The third and final video for chapter 16… again it is available on movenote or youtube. Here we will talk about speciation and the Grants and their observation of finches changing over time.

  1. A species is a group of animals that can reproduce together, and more than 99% of species are extinct.

  2. The bigger beaks came in more handy dureing the drought this is because the seeds got bigger so the bigger brakes helped them said the grants

  3. I learned that more than 99% of species are extinct and reproductive isolation is the one that makes new species

  4. I have learned that about 99% of the unique species on earth since 4.6 billion years ago are extinct.

  5. Geological events may favor a certain species, which will go on to produce more and become the average of that variation of the species.

  6. 99% of species will most likely become extinct meaning there may be a couple left but they are endangered.
    – Dylan Kemmet

  7. The fiches have different beaks and there the same bird. The differences are called variations

  8. The finches of the Galopougues Islands have many different beaks. Has to do with natural selection(the force behind the differences). These differences are called variations.

  9. The finches of the Galopougues Islands have many different beaks, when they all were from the same bird. This has to do with natural selection, which is the force behind the differences. These differences are called variations, the basis for evolution.
