    Dinosaurs

     

    (Roughly) Daily recently considered the newly-unearthed fossil record of the asteroid strike that led to the extinction of the dinosaurs.  But what if that asteroid had missed?

    An asteroid slammed down and did away with all the dinosaurs, paving the way for such developments as the human race, capitalism, and posting on the internet: it’s the story we all know and love. Yet if things had shaken out differently—if the asteroid had stayed in its place, and the dinosaurs allowed to proceed with their business—what would things have looked like?

    Would the earth be a pristine, unsmogged paradise, or would the dinosaurs have somehow evolved into even more rapacious profiteers/industrialists, wrecking the world with their dinosaur refineries and dinosaur dark money? The latter scenario being totally implausible, what’s a likely answer to the question of what our world would look like if that asteroid never hit it?…

    Nine scientists– geologists, paleontologists, and evolutionary biologists– provide some fascinating “alternative history”: “What If the Asteroid Never Killed the Dinosaurs?

    As we explore the road not taken, we might recall that it was on this date in 1869 that the American Museum of Natural History was incorporated.  Its founding had been urged in a letter, dated December 30, 1868, and sent to Andrew H. Green, Comptroller of Central Park, New York, signed by 19 persons, including Theodore Roosevelt, A.G. Phelps Dodge, and J. Pierpont Morgan.  They wrote: “A number of gentlemen having long desired that a great Museum of Natural History should be established in Central Park, and having now the opportunity of securing a rare and very valuable collection as a nucleus of such Museum, the undersigned wish to enquire if you are disposed to provide for its reception and development.”  Their suggestion was accepted by Park officials; the collections were purchased– and thus the great museum began.  It opened April 27, 1871.

    Meteors

     

    The odds of being hit by a meteorite are extremely low. You’re far more likely to die in a car crash or a fire than you are to die from a meteorite strike. It’s also more likely that you’ll be killed by lightning or a tornado – both of which are extremely rare. However, there’s bad news too – you have a higher chance of being hit by a meteorite than you do of winning the lottery…

    Oh, and avoid the United States (and India)!  See why at: “What Are Your Chances of Being Hit by a Meteorite?

    * Henry Wadsworth Longfellow

    As we duck and cover, we might recall that it was on this date in 1969 that a large meteorite fell near Murchison in Victoria, Australia.  Both because it was an observed fall (its bright fireball was seen by many) and because it proved to be rich in organic compounds (an abundance of amino acids), it has been one of the most-studied meteorites.
