Giraffes have evolved to exploit a particular ecological niche, which is, that they graze on tree leaves, which few animals are tall enough to reach. Whenever you have a niche that is not being exploited, that creates an evolutionary opportunity. There are many different animals that graze on grass, for example, so there is competition to eat the grass before some other species eats it, but leaves that are high off the ground are grazed on by very few animals (not counting insects, which are another matter - in any confrontation between a giraffe and an insect, the giraffe has a clear advantage).

Why do giraffes evolved with long necks?
Giraffes evovled with long necks so they can reach the tree and eat the leaves.
What would need to happen so that giraffes with really long necks evolved?
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.
What did whales evolve from?
They evolved from even toed ungulates, or animals with even hoofs like cows and giraffes.
Do all giraffes have the same pattern?
It has evolved to have a long neck to reach the leaves higher up in the trees
How is giraffes adapted to its environment?
i think their necks grow & evolved eventually because of the lack of low trees and branches
Why did Darwin believe that only a small number of offspring survive?
It wasn't exactly that. Darwin believed that species evolved through natural selection. Meaning the individual that's best suited for the environment survives. So for example giraffes. As the food started getting harder and harder to reach only giraffes with longer necks would survive. Hence giraffes have freakishly long necks now
Do giraffes eat other giraffes?
no never eat other Giraffes.
Do giraffes have knees?
Yes, giraffes do have knees.
Do giraffes get harmed?
Giraffes can get harmed
Are giraffes carnivores?
No. Giraffes are herbivores.
What eats acacia?

Scientist believe the first giraffes on earth had shorter legs and shorter neck then giraffes today?
The first known member of the giraffe family, Climacoceros, was a deer like animal. As time went on and the giraffes became browsers (leaf eaters), they evolved longer necks and legs to reach leaves that were too high for other animals. Eventually, all short necked species of the giraffe family, except the okapi, became extinct.
