Introduction

Why do giraffes' have long necks?

• hypothesis:
  • to eat food from trees
  • to avoid predators

null hypothesis: the hypothesis we expect to see if our original hypothesis turns out to be not true

• observation(s):
  • what they use their height for
  • feeding behaviors
  • use a large sample size
  • what are they eating from

In 1991 they modeled the feeding of a male and female giraffe. On average giraffes eat food that is found at a shorter height than their own height.

• actuality:
  • longer necked giraffes win mating matches
