Elisabeth Vrba

Elisabeth S. Vrba (Hanburgo, 1942ko maiatzaren 17a - New Haven, 2025eko otsailaren 5a) hegoafrikar paleontologoa  izan zen, aldaketa pultsuaren hipotesia garatu zuelako eta Stephen Jay Gould lankidearekin exaptazio hitza sortu zuelako ezaguna.

 Ibilbidea 
Vrba Hanburgon jaio zen, Alemanian. 1944an, aita hil ondoren, familiarekin batera Namibiako ardi-ustiategi batera joan zen bizitzera. Vrba 1965ean Zoologia eta Estatistikan graduatu zen  eta baita ere zientzietako batxiler gisa  Lurmutur Hiriko Unibertsitatean. 1966 eta 1967 artean biologia molekularrean ikerkuntzan aritu zen. 1968an bigarren hezkuntzako irakasle gisa lan egin zuen Pretoriako San Alban Ikastetxean. 1969tik aurrera, Pretoriako Transvaal Museoko Paleontologia eta Paleoantropologia sailean lan egin zuen. Zoologian eta paleontologian doktoretza ikasketak egiteko egon zen han, doktoretza lortzeko. 1973tik 1986ra Transvaal Museoko Paleontologia eta Paleoantropologia saileko burua izan zen. Zoologia eta Paleontologia doktoregoa lortu zuen 1974an. Bobidoen familian (antilopeak, etab.) garatu zuen bere lana. Doktoretza jaso ondoren, Vrbak Afrikako azken milioi urteetako erregistro fosilei buruzko ikerketak egin zituen, fosilen sekuentzia arakatuz, geruza geologikoak aztertuz eta fosilen morfologia aztertuz. 

Kromdraai guneko indusketa-zuzendaria izan zen 1976 eta 1986 artean, eta Transvaal Museoko zuzendari laguntzailea 1977 eta 1986 artean. 1986an Estatu Batuetara joan zen, Yale Unibertsitateko Geologia eta Geofisika Sailean unibertsitateko katedradun izateko. Peabody Museoko  arduraduna zan zen 1987tik. 1995ean Yale Unibertsitateko Geologia eta Geofisika Saileko lehendakaria izan zen. 1996 eta 1999 bitartean Yaleko Zientzia Bioesferikoaren Institutuko zuzendaria izan zen, eta 1992-2010 bitartean Unibertsitate bereko Ecosave Zentroko zuzendaria.

 Berrikuntzak 
Vrba eta bere lankide Stephen Jay Gould exaptazioaren teoriagatik dira ezagunak. Vrba eta Goulden ikerketak ezaugarri genetiko baten jatorri historikoak ez duela beti bere funtzio garaikidea islatzen iradoki zuen.  Egokitzapen genetikoek funtzio berriak har ditzakete, eta eboluzioan aurrerago beste helburu bat lortzeko balio diezaiokete espezie bati. Vrba eta Goulden exaptazioaren ideia ere kritikatu dute azken urteotan adituek, ezaugarri genetikoak hainbat faktoreren presiopean daudela baieztatzen baitute, eta horrek zaildu egiten du noiz dagoen egokitzapena edo exaptazioa jokoan zehaztea.

Vrbak aldaketa-pultsuaren hipotesia ere garatu zuen, teoria makroebolutiboaren gehigarri esanguratsua. 

 Hedabideetan agerpenak 
Vrbak Planeta Milagroso (2005) dokumental sailean eta Ein Zufall im Paradies (1999) dokumental austriarrean parte hartu du bere burua aurkeztuz.
