  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

    -Taylor Kool

  4. A Species has a common gene pool because they can share all of the genes together

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

  13. 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.

  14. Members of two populations can not interbreed and make fertile offspring
    By Raigan Mettenbrink

  15. 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.
