Question

Why do giraffe's have long necks?

Answer 1

to reach food in high tree's

Answer 2

according to Larmacks theory, girrafes have a long neck due to evolution. they survived by ingesting leaves from tree tops and thus their necks grew long as time passed. Those with short neck were outdone by the long-necked giraffes due to need for survival.

Answer 3

what frediwhi said

Answer 4

Because it's the way that nature intended.

Answer 5

because they are descendants of long necked dinosuars that eventuall evolved in due time into a giraffe.

they use it for grabbing tree leaves in high places and for fast running but also post as a disadvantage as they need to plit their legs in order to dring water from a lake

it's in their genes now and it'll change again after...at the very least....1 million years just like the dinosaurs have evolved

Answer 6

Because they do.

Answer 7

One suspects good old evolution: The longer the neck, the more leaves you get to eat. I have seen deer competing for apples the same way, except they reach by standing on two legs instead.

Giraffes also graze on the ground, but have to spread their front legs to reach it. BTW, they have the same number of vertebrae in their necks as we do: 13.

Answer 8

The trees are really tall in Kenya so I would guess they evolved to be able to reach the leaves.
