Why do giraffes have long necks?

1. 1

   Lue says

   Giraffes eat leaves, and they love tall, thorny trees called acacias. Lots of animals eat leaves, but most can only reach the low ones. A giraffe's long legs and long neck lift its head right up into the treetops. So it can munch leaves that few other animals can reach.

   Why is a giraffe's neck so much longer than mine?

   Feel the back of your neck. Inside are seven little bones stacked up. A giraffe has seven neck bones too, the very same number! But each of its neck bones is much, much bigger. So seven giraffe bones stack up into one very tall neck.
