What accounts for the great range of neck length in those four mammals is simply the length of each individual vertebra. This forest-dweller has a shorter neck, just like the extinct species from which both it and giraffes are thought to have evolved. Their excuse for the killing the giraffe was that they were worried about inbreeding. Charles Darwin famously proposed that giraffes evolved long necks due to competition over food; by being ridiculously tall, the animals could consume foliage that remained out of reach to other animals.

Darwin explains that individuals with characteristics better adapted to their environment are more likely to survive and therefore, such traits are inherited.
These giraffes are a prize for poachers and their population has decreased dramatically since the year 2000. It has a big body like horses, a lengthy (but not as long) neck, and a similar face to giraffes.
