 Question: can you have a heart attack from laughing Context: During the Beagle survey expedition, the young naturalist Charles Darwin had remarkable success with fossil hunting in Patagonia. On 10 October 1833, at Santa Fe, Argentina, he was ``filled with astonishment'' when he found a horse's tooth in the same stratum as fossil giant armadillos, and wondered if it might have been washed down from a later layer, but concluded this was ``not very probable''. After the expedition returned in 1836, the anatomist Richard Owen confirmed the tooth was from an extinct species, which he subsequently named Equus curvidens, and remarked, ``This evidence of the former existence of a genus, which, as regards South America, had become extinct, and has a second time been introduced into that Continent, is not one of the least interesting fruits of Mr. Darwin's palæontological discoveries.''
 Question: are there any predecessors or extinct species horses Context: There are many different methods of rendering Greek text or Greek names in the Latin script. The form in which classical Greek names are conventionally rendered in English goes back to the way Greek loanwords were incorporated into Latin in antiquity. In this system, ⟨κ⟩ is replaced with ⟨c⟩, the diphthongs ⟨αι⟩ and ⟨οι⟩ are rendered as ⟨ae⟩ and ⟨oe⟩ (or ⟨æ,œ⟩) respectively; and ⟨ει⟩ and ⟨ου⟩ are simplified to ⟨i⟩ and ⟨u⟩ respectively. In modern scholarly transliteration of Ancient Greek, ⟨κ⟩ will usually be rendered as ⟨k⟩, and the vowel combinations ⟨αι, οι, ει, ου⟩ as ⟨ai, oi, ei, ou⟩ respectively. The letters ⟨θ⟩ and ⟨φ⟩ are generally rendered as ⟨th⟩ and ⟨ph⟩; ⟨χ⟩ as either ⟨ch⟩ or ⟨kh⟩; and word-initial ⟨ρ⟩ as ⟨rh⟩.
