Three years after this puzzling observation, scientists spotted an 8.5-foot-tall, Angolan giraffe on a private farm in Namibia. The team named him Nigel, reports the Times. Dinosaurs are classified as reptiles, a group that includes crocodiles, lizards, turtles, and snakes. Of this large group of animals, other than birds, crocodiles are the closest living things to dinosaurs. Is a Brachiosaurus taller than a giraffe?According to a statement from the Giraffe Conservation Foundation, this is the first time that dwarfism has been documented in captive or wild giraffes. The scientists published their findings in December in the journal BMC Research Notes. Bagemihl, B. (1999). Biological Exuberance: Animal Homosexuality and Natural Diversity.

A 2020 study showed that depending on the method chosen, different taxonomic hypotheses recognizing from two to six species can be considered for the genus Giraffa. [23] That study also found that multi-species coalescent methods can lead to taxonomic over-splitting, as those methods delimit geographic structures rather than species. The three-species hypothesis, which recognises G. camelopardalis, G. giraffa, and G. tippelskirchi, is highly supported by phylogenetic analyses and also corroborated by most population genetic and multi-species coalescent analyses. [23] A 2021 whole genome sequencing study suggests the existence of four distinct species and seven subspecies. [24] Darwin explains that individuals with characteristics better adapted to their environment are more likely to survive and therefore, such traits are inherited. He also said that species that can not compete and adapt eventually become extinct. Exhibits". Al Ain Zoo. 25 February 2003. Archived from the original on 29 November 2011 .
