Researchers from the International Union for Conservation of Nature (IUCN) have announced that there are three more species of giraffes than previously acknowledged, expanding the iconic animal’s classification from one to four distinct species. This groundbreaking finding comes as researchers have meticulously analyzed genetic data, skull sizes, and head shapes to confirm the genetic diversity that substantiates their claims.
The newly recognized species includes the Southern giraffe, native to regions like Angola, Botswana, Namibia, Zimbabwe, Zambia, and Mozambique. Researchers indicate that natural geographical barriers such as the Kunene and Zambezi rivers and the Congo Basin rainforests have contributed to this species' distinct evolution away from its counterparts.
Another addition is the Reticulated giraffe, which roams savannas and grasslands throughout Kenya, Somalia, and Ethiopia. The study suggests that geographical features such as the Tana River and Ethiopian mountains have effectively isolated it, preventing interbreeding with other giraffes in the area. Notably, this species is also characterized by a migratory pattern, presenting additional complexities in their classification.
The Northern giraffe, which can be found in western Ethiopia, parts of central Kenya, and eastern South Sudan, makes up the third identified species, separated by natural barriers including the Nile River and Lake Victoria. Its migration further isolates it from other populations of giraffes.
Completing this quartet is the Masai giraffe, identified by its unique leaf-patterned coat. This species inhabits regions of Kenya, Tanzania, and Uganda, with the Nile River and Lake Victoria serving as barriers to its relatives, notably the Northern giraffe. Despite the initially distinct patterns observed in Masai giraffes, scientists warn that variations can occur within individual populations over time.
The IUCN underscores the importance of this taxonomic understanding, stating it is crucial for effective conservation strategies. "Understanding the precise differences within giraffe populations allows us to better evaluate their statuses and implement more effective conservation tactics," asserts report co-author Michael Brown from the IUCN.
Previously considered a single vulnerable species, the IUCN initiates a re-evaluation of the conservation statuses for the four new species and their respective sub-species, aiming to enhance protections for these magnificent creatures.
