🦒 Recent genomics research confirms four distinct giraffe species, revealing extensive hybridization in North American captive populations. To ensure effective conservation, authors recommend phasing out hybrids and creating new, genetically pure stocks through international collaboration.

This occurs due to the process of regressive evolution. In an environment without light, vision provides no advantage in finding prey or avoiding predators. The loss of their eyes means that energy and resources once used for eyes are instead allocated to other traits.
