The diagnosis of elephant poultry bones, once the ideal poultry in the sphere, has printed that humans have arrived on the tropical island of Madagascar more than 6,000 years ago. They seem to have lived alongside important birds for thousands of years, hunting them and skinning them for food as needed. Apart from pushing the participants to the date of human migration to Madagascar, the site brings a contemporary light on the human function in the extinction of the megafauna of the island.
A team of scientists led by ZSL (Zoological Society of London) realized that obsolete bones of Madagascar's elephants (Aepyornis and Mullerornis) were extinguishing and marking hunger and butchery depression fractures by prehistoric humans . The elephants weighed at least half a ton, had been at least three meters (eighty-four toes.) And had huge eggs laid.
Using radiocarbon dating techniques, the team was then unable to investigate when these large birds were killed, re-evaluating the time humans first reached Madagascar. They published their findings in the journal Science Advances.

Exceeded research on lemur bones and archaeological artefacts has led humans to arrive in Madagascar for the first time 2,440 years ago. Conversely, the contemporary scene bears witness to the human presence in Madagascar, as evidenced by the old way of seeing them 10 500 years ago – making these modified elephant bones the first known human evidence on the planet.

The senior writer, Dr. James Hansford of the ZSL Zoology Institute acknowledged, "We already know that Madagascar's megafauna – elephant, hippopotamus, large turtle and massive lemurs – has disappeared less than a thousand years ago. There are different theories about why this happened, but the extent of human involvement has not been distinct. He endured:
"Our research has proven human exercise in Madagascar more than 6,000 years earlier than previously thought – demonstrating that a radically matched idea of extinction is needed to mark the massive loss of biodiversity that has occurred. is produced on the island. For more than 9,000 years, people seem to have coexisted with elephant birds and other species that are now extinct. This seems to have a limited negative impact on biodiversity for most of this period, which now gives ideas for conservation.

The co-writer, Professor Patricia Wright of Stony Brook College, acknowledged:
"This contemporary discovery reverses our idea of the first human arrivals. Everyone is aware at the end of the ice age, when men had resorted to stone tools, there was a men's quarter that had arrived in Madagascar. We no longer know the muse of these people and luckily, by chance and luck, we will not have any more archaeological evidence, but we know that there will be no more proof of their genes. much like the moment of the people. The query remains – who were these people? And when and why did they go back?

The bones of the elephants studied by this mission predated what had been done in 2009 in the Christmas River in south-central Madagascar – a fossil bone bed with a rich concentration of obsolete animal remains. This swamp space would be a very famous homicide space, but further research is needed to justify it.
