Most recently, researchers proposed dividing them into up to eight extant species due to new research into their mitochondrial and nuclear DNA, as well as morphological measurements. [20] A 2011 study using detailed analyses of the morphology of giraffes, and application of the phylogenetic species concept, described eight species of living giraffes. The value of legacy system connectivity. [12] The Tugen people of modern Kenya used the giraffe to depict their god Mda.
