Speologie Speologi într-o peşteră Speologia (din greacă σπηλαιοv, spelaion adică peșteră și λόγος, logos adică știință) este activitatea de a identifica, explora, studia, cartografia și vizita locații subterane (peșteri, caverne). Cel care practică speologia se numește speolog. Încă de la începuturi, ea a fost practicată atît de către specialiști cât și de către amatori. Fiind o activitate solicitantă fizic și financiar, se practică mai intens în țările cu nivel de trai ridicat. Suprafața uscatului este acoperită în procent de 20 la sută de roci carstificabile. Începuturile[modificare | modificare sursă] Înainte de a doua jumătate a secolului al XIX-lea sunt studiate unele peșteri sporadic și conjunctural, cum ar fi din interes militar. Întemeierea ca și știință are loc în a doua jumătate a secolului XIX, de către fr Édouard-Alfred Martel de profesie avocat. Emil Racoviță face cercetări tot mai specializate astfel în 1907 pune bazele biospeologiei. Domenii implicate[modificare | modificare sursă]

Ancient humans, dubbed 'Denisovans', interbred with us 22 December 2010Last updated at 18:03 By Pallab Ghosh Science correspondent, BBC News Professor Chris Stringer: "It's nothing short of sensational - we didn't know how ancient people in China related to these other humans" Scientists say an entirely separate type of human identified from bones in Siberia co-existed and interbred with our own species. The ancient humans have been dubbed Denisovans after the caves in Siberia where their remains were found. There is also evidence that this group was widespread in Eurasia. A study in Nature journal shows that Denisovans co-existed with Neanderthals and interbred with our species - perhaps around 50,000 years ago. An international group of researchers sequenced a complete genome from one of the ancient hominins (human-like creatures), based on nuclear DNA extracted from a finger bone. 'Sensational' find DNA from a tooth (pictured) and a finger bone show the Denisovans were a distinct group 'Fleeting encounter'

"That does sound like the sort of thing I would do, doesn't it?" It was breakfast time on Friday morning. But dungeons! "Harry Potter," said a quiet voice from behind him. Harry looked over his shoulder and found himself beholding Ernie Macmillan, smartly dressed in yellow-trimmed robes and looking a little worried. "Neville thought I should warn you," Ernie said in a low voice. There was a pause as Harry processed this, and then he lifted his eyebrows. Ernie nodded, and turned to go back to the Hufflepuff table. Harry resumed eating his toast. It was around four bites afterward that someone said "Pardon me," and Harry turned around to see an older Ravenclaw, looking a little worried - Some time later, Harry was finishing up his third plate of rashers.
