so they can reach the leaves in high, hard to reach places.
Giraffes evovled with long necks so they can reach the tree and eat the leaves.
because your mom said so
on their necks
no
I'm guessing that food was scarce near the bottom of trees, so giraffes with longer and longer necks generally outlived the giraffes with shorter ones.
The reason why giraffes necks get so long is because they have to eat and the stuff that they eat is on the trees so they have to have long necks to get the stuff off the tree
They are tall and have long necks
They have long necks
giraffes have long necks and spots
I LOVE giraffes. There necks don't seem that long to me. They are intelligent
Lamarck would explain the development of giraffes with long necks as a result of the giraffes stretching their necks to reach higher leaves, and passing on this acquired trait to their offspring. This is known as the theory of inheritance of acquired characteristics.
As giraffes eat leaves on taller trees, they have adapted long legs and long necks so they can easily reach the leaves on the taller trees.
