giraffeStudies have revealed that the long neck of the modern day giraffe evolved in several stages to reach its present stature. The animal’s vertebrate stretched first towards the head and then towards the tail, a few million year ago. Scientists have long theorized that the long neck helps the modern-day giraffes to find more vegetation or develop a specialized technique of fighting. First only the front portion of the C3 vertebra lengthened in one group of series and at second stage the elongation of the back portion of the C3 neck vertebra took place. The modern giraffe is the only species that underwent both evolutions, which is why this remarkably long neck. The fossils reveal that the lengthening started before the giraffe family was even created 16 million years ago.
