Histoire Naturelle , 1700s
In 2012, Leo Joseph and colleagues acknowledged the finding but pointed out that the sample might have been damaged and that further testing was needed before the issue could be fully resolved. They also noted that if
Mascarinus was confirmed to be embedded within the genus Coracopsis , the latter would become a junior synonym, since the former name is older. [16] In 2012, Hume expressed surprise at these findings due to the anatomical similarities between the Mascarene parrot and other parrots from the Mascarene islands that are believed to be psittaculines. He also pointed out that there is no fossil evidence found on other islands to support the hypothesis that the species evolved elsewhere before reaching Réunion. [8]
In 2017, Lars Podsiadlowski and colleagues sampled the Vienna specimen for a new genetic study and found that the Mascarene parrot was indeed part of the Psittacula group as suggested by Hume, clustering with the extinct
Seychelles parakeet (P. wardi ) and Asian subspecies of the Alexandrine parakeet (P. eupatria). The Mascarene parrot was therefore interpreted as having descended from an ancestral lineage of Alexandrine parakeets that had dispersed from Asia towards the Mascarene islands across the Indian Ocean. The researchers suggested that the 2011 genetic study had probably used a composite of sequences from two other parrot species sampled for the study (including a lesser vasa parrot), a result of contamination during laboratory procedures. The 2017 study also found that the parrots of the genus Tanygnathus were grouped among
Psittacula parrots, and proposed that Tanygnathus and Mascarinus should therefore be merged into the genus
Psittacula . The cladogram accompanying the 2017 study is shown below:[17]
Mascarinus mascarin
Psittacula wardi (Seychelles , extinct)
Psittacula eupatria nipalensis (Central Asia )
Psittacula eupatria magnirostris (Andaman Islands )
Psittacula eupatria siamensis (Southea

Commit to Excellence to archive your goal

  The quality of your life will be determined by the depth of your commitment to excellence, no matter what your chosen field. —VINCE LOMBARDI  RESOLVE TODAY TO be the very best at what you do. Set a goal for yourself to join the top 10 percent of your field, whatever it is. This decision, to become very, very good at what you do, can be the turning point in your life. Virtually all successful people are recognized as being extremely competent in their chosen fields. Remember that no one is better than you, and no one is smarter than you. And everyone who is in the top 10 percent today started off in the bottom 10 percent.  Everyone who is doing well was once doing poorly. Everyone who is at the top of his or her field was at one time in another field altogether. And what countless others have done, you can do as well. Here is a great rule for success: Your life only gets better when you get better. And since there is no limit to how much better you can become, there is n...

what is the most frightening thing that you have ever seen happen in life

It’s a man looking over his family during the British Raj in India. There were many cases of cannibalism and he feared someone would try to kill and eat his children or wife. I acknowledge this is a difficult picture to look at— but I included it for a reason. Many people in the US/West aren’t even aware of the terrible famines that swept through India and which are comparable to the holocaust in deaths (an estimated ~30 million people have died in famines in India). This was taken from the Great Famine of 1876–1878, which was far worse than the infamous Bengal Famine. It was caused by a crop failure/drought and was exacerbated by the crown’s export of wheat abroad. In total, 5.6 - 9 million people died (it’s hard to get exact figures). And within huge statistics like these, are forgotten stories. These are individuals and families, who slowly faced the despair of knowing they had no food and would have no food in the near future. They faced the horror of knowing there was ...
