Why are there no short neck giraffes?
Natural selection weeds out the unadapted and the best-adapted survive. These variations become dominant in the species and so it evolves.

Has there ever been a giraffe with a short neck?
For years, there has been scant fossil evidence showing how the giraffe evolved to have such an admirably long neck. But now, the remains of a 7-million-year-old creature with a shorter neck provide proof that the giraffe’s iconic feature evolved in stages, lengthening over time, a new study finds.
Why do giraffes have long necks 2020?
It appears obvious: the giraffe’s neck, which can grow to as much as two metres in length, has been selected because it gives its owner exclusive access to the topmost leaves of the trees, and no other animal can reach them. This, then, is an adaptation designed to avoid competition for food with other animals.
How did giraffes long necks evolve?
The latest theory – and it’s a surprise this hasn’t come up before, given biologists’ fixation with it – is that the long necks are the result of sexual selection: that is, they evolved in males as a way of competing for females. Male giraffes fight for females by “necking”.
