The variation (strange traits) were caused by _____________________. 2.In this environment, the mutation that was advantageous was ____________. 3.This mutation was helpful because ______________________________ 4.The mutation was passed down to their offspring because _____________________

  21. more food • more protection more offspring & therefore is MORE FIT good • less food • less protection less offspring & therefore is LESS FIT bad

  22. Pg 60 The Evolution of the Giraffe Millions of years ago, the ancestors of ____ had ____________ But due to random mutations, there was variation. Some had slightly __________. The ones with slightly _______were able to compete by _____________. In this environment, ______ were an_______, so they were able to survive and ________more. Over millions of years, the ______with ________died out, while the _________ reproduced and _________________ That is how the ----- evolved and why today, we have _____with __________.

  23. The Evolution of the Giraffe Millions of years ago, the ancestors of giraffes had short necks, and ate mostly grass. But due to random mutations, there was variation. Some had slightly longer necks. The ones with slightly longer necks were able to compete by eating the leaves from trees. In this environment, longer necks were an advantage, so they were able to survive and reproduce more. Over millions of years, the giraffes with shorter necks died out, while the longest necks reproduced and passed down their traits to their offspring. That is how the giraffe evolved and why today, we have giraffes with very long necks.
