Madagascar (TV series) in March 2011. In this one-off programme, David Attenborough undertakes a personal journey back to Madagascar to investigate the fate of "Aepyornis", the island's extinct elephant birds. Believed to be the largest birds which have ever lived, evidence of their existence can still be found on the island. Whilst filming "Zoo Quest to Madagascar" in 1961, Attenborough pieced together a complete elephant bird egg from fragments of shell collected for him. "Madagascar" was first announced in March 2009 as a partnership between Animal Planet and BBC Worldwide. Production duties were handled by the BBC Natural History Unit in Bristol, with
African elephant date between forest and savanna elephants was 2.6 – 5.6 million years ago, similar to the divergence date estimated for the Asian elephant and the woolly mammoths (2.5 – 5.4 million years ago), which strongly supports their status as separate species. Forest elephants were found to have a high degree of genetic diversity, perhaps reflecting periodic fragmentation of their habitat during the climatic changes of the Pleistocene. However, recent DNA sequence analysis indicates that the extinct European straight-tusked elephant, "Palaeoloxodon antiquus", is closer to "L. cyclotis" than "L. cyclotis" is to "L. africana", thus invalidating "Loxodonta" as currently recognized.
