They do not have short necks. They have very long necks.
compared to their body size they have short necks because when they try to drink water they have to spread out their legs to reach water so they could be attacked and if they were they would be very vulnerable.
Giraffes with small necks are most likely to starve because they can't reach tall trees.
or
Young giraffes with short necks their neck are probably going to grow.
I don't know witch answer is for your question.
No, a giraffes have long necks to get the leaves off trees.
You may be thinking of the Okapi which is the only other member of the Giraffidae family.
It is tall. it is tall and spottty. It's neck is about 6 feet long.
Charles Darwin
Because if they had short necks they would be horses.
No, giraffes are all long necked. If an animal has a short neck, it is a different species of animal.
so they can reach leaves from trees its hard if they were short and there necks to
No. Genetics is a topic in biology. I think what you mean is, the mutations that form in DNA to give different features may be beneficial to the survival of the organism. E.g. Giraffes with long necks are more likely to survive than the giraffes with short necks because they can reach leaves on higher trees but the short giraffes can not. The short giraffes have evidently become extinct as a result.
Giraffes use their necks in the same way we use ours. They are just longer.
Lamarck would have said that the ancestors of modern-day giraffes had short necks but stretched their necks as they tried to reach leaves in trees; so, their descendants were born with longer necks. Darwin would have said that in a population of ancestral giraffes, some had slightly longer necks than others; the long-necked giraffes were better able to feed on tree leaves and as a result produced more offspring. Over time, the proportion of longnecked giraffes in the population increased.

Yes, they do.
Giraffes evovled with long necks so they can reach the tree and eat the leaves.
no
on their necks
