Cryptic African Wolf: Canis Aureus Lupaster Is Not a Golden Jackal
ScienceDaily (Jan. 26, 2011) — New molecular evidence reveals a new species of grey wolf living in Africa. Formerly confused with golden jackals, and thought to be an Egyptian subspecies of jackal, the new African wolf shows that members of the grey wolf lineage reached Africa about 3 million years ago, before they spread throughout the northern hemisphere.
As long ago as 1880 the great evolutionary biologist Thomas Huxley commented that Egyptian golden jackals -- then as now regarded as a subspecies of the golden jackal -- looked suspiciously like grey wolves. The same observation was made by several 20th Century biologists studying skulls. Nonetheless, the conventional taxonomy has not been changed. A new study, involving a collaboration of biologists from the University of Oslo, Oxford University's Wildlife Conservation Research Unit (WildCRU) and Addis Ababa University, has uncovered genetic evidence that unambiguously places the Egyptian jackal within the grey wolf species complex. It is not a jackal, but a wolf, taxonomically grouped with the Holarctic grey wolf, the Indian wolf and the Himalayan wolf. Dr Eli Rueness, the first author of the paper, states that "We could hardly believe our own eyes when we found wolf DNA that did not match anything in GenBank."
The genetic data indicate that the Indian and Himalayan wolves evolved as separate taxa within the modern wolf cluster even before the grey wolf radiated throughout the northern hemisphere. Furthermore, not only did these two types of wolves originate before grey wolves radiated in northern latitudes, but the wolfish colonization of Africa took place before the grey wolf radiation as well. The colonization of Africa by the ancestral stock of grey wolves took place about 3 million years ago and is today embodied by the animal that has hitherto been called the Egyptian jackal. Professor Claudio Sillero, of the WildCRU and current Chairman of the IUCN's Canid Specialist Group, added that "Ethiopian wolves split off from the grey wolf complex even earlier than the newly discovered African wolf."
The Oslo/WildCRU/Addis Ababa team also found genetically very similar specimens 2,500 km from Egypt, in the highlands of Ethiopia. Golden jackals are regarded by the IUCN (International Union for Conservation of Nature) as not endangered -- a "species of least concern" -- but the newly discovered African wolf may be much rarer. Certainly, it is a priority for both conservation and science to discover its whereabouts and numbers. Professor David Macdonald, an author of the paper and Director of Oxford's WildCRU, remarks that "A wolf in Africa is not only important conservation news, but raises fascinating biological questions about how the new African wolf evolved and lived alongside not only the real golden jackals but also the vanishingly rare Ethiopian wolf, which is a very different species with which the new discovery should not be confused." It seems that the Egyptian jackal is urgently set for a name-change, and its unique status as the only member of the grey wolf complex in Africa destines it to be re-named the African wolf.
According to Professor Nils Chr. Stenseth, an author of the paper and the Chair of the Centre for Ecological and Evolutionary Synthesis (CEES), "This study shows the strengths of modern genetic techniques: old puzzles can be solved." "This shows how genetic techniques may expose hidden biodiversity in a relatively unexplored country like Ethiopia," concludes Professor Afework Bekele at Addis Ababa University.

Egyptian jackal is actually ancient wolf

January 26, 2011
The Egyptian jackal, which may have been the inspiration for the Egyptian god Anubis, is actually not a jackal at all but a member of the wolf family. New genetic research in the open-access journal PLoS ONE finds that the Egyptian jackal is Africa's only member of the gray wolf family. The new wolf, dubbed by researchers as the African wolf, is most closely related to the Himalayan wolf.
"We could hardly believe our own eyes when we found wolf DNA that did not match anything in GenBank," lead author, Dr Eli Rueness, said in a press release. GenBank is an open-access nucleotide database.
The genetic data also points to an early origin for the Egyptian jackal/African wolf. In fact, researchers believe the animal is older than well-known wolves of the northern hemisphere. According to the study, Indian, Himalayan, and the new African wolf, broke off from the gray wolf before it moved north, colonizing Europe, northern Asia, and the Americas, further subdividing into different subspecies. Ethiopian wolves, which are a unique species of canids, are older still.
Long suspected by some biologists, genetic research has shown that the Egyptian jackal is actually a wolf.
The study does not appear to make a recommendation whether or not this new wolf should be considered a unique species in its own right or another subspecies of the grey wolf (Canis lupus). Currently, gray wolf subspecies number in the thirties, and distinction between species and subspecies continues to be debated for a number of them.
However the new African wolf is classified, researchers argue the discovery must change how the animal is viewed in conservation. The authors call for the African wolf to be assessed individually, especially considering evidence that the animal is rare. The animal is not protected in Egypt and is often persecuted as it is considered a threat to livestock.
In good news, the researchers discovered that the African wolf, previously Egyptian jackal, is actually present in the Ethiopian highlands, expanding its known range considerably.
"This study shows the strengths of modern genetic techniques: old puzzles can be solved," Nils Chr. Stenseth, Chair of the Centre for Ecological and Evolutionary Synthesis (CEES) and an author of the paper, says.

Re: Chacal egipcio no es un chacal, sino un lobo!
Da gusto salsear en este foro, hace menos de un año que hablamos de este tema y ¡ZAS! NOTICION, los chacales con supuesta introgresión genética de perro, vamos hÃbridos de perro y chacal eran en realidad lobos, lobos puros.
Me imagino que llegados a este punto habrÃa que mirar por todo el norte de Africa por que en Libia también se han solido ver chacales rarillos.

Re: Chacal egipcio no es un chacal, sino un lobo!
Pues la noticia a mi me crea cierto malestar, porque nuevamente un bicho asà ha sido completamente despreciado, cuando estaba delante de nuestras narices. Ahora practicamente no se sabe nada de él, por no haber no hay casi ni fotos. ¿En qué medida ha sido exterminado el animal en su hábitat, con certificado cientÃfico , "por ser sólo un chacal?
La biologÃa no me parece inocente ni en este caso, ni en otros.

Re: Chacal egipcio no es un chacal, sino un lobo!
A mi me parece más "propenso" a ser disparado si es un lobo qué no un chacal...

Y me recuerdo de esa conversa sobre algunos estraños chacales norte africanos...
Re: Chacal egipcio no es un chacal, sino un lobo!
Adjunto las fotos que aportó Rachid al post de Fauna Marroquà en la que aparece el "chacal" que curó y recuperó con sus manos, en la foto en la que posa encima de una tortuga y subido a una caja de madera se le ve casi adulto y a mi me resulta un chacal rarito.

Re: Chacal egipcio no es un chacal, sino un lobo!
RAB, pero no mucho más, porque si ya al chacal se le tiene que perseguir por todos los medios, ¿cuanto más podrÃa ser si "fuera lobo"?
Por otro lado, llevarÃa muchas décadas protegido.
Como sugerÃs, a mi también me parece que esto abre la posibilidad de que el lobo esté o haya estado presente "de incognito" por todo el norte de Africa, hasta Marruecos, el Sahara etc...
Para mi es otra prueba de que la biologÃa ortodoxa no deberÃa ser tan prepotente y cerrada, porque ya se ve que mete a menudo la pata hasta el fondo.

Re: Chacal egipcio no es un chacal, sino un lobo!
Imagen clara de un lobo africano (Canis lupus lupaster) aquà si se ve un lobo y no un chacal (Canis aureus).

Re: Chacal egipcio no es un chacal, sino un lobo!
lo que yo no entiendo es como veian un chacal en este animal, si parece un lobo en todas las fotos que he visto.
De todas formas, a mi me extrañaba mucho que no hubiese lobos en el norte de Ãfrica. Si hasta habia osos!! Y como bien dice Jonas, habria que ver esos chacales marroquÃes que vimos en unas fotos...
¿Alguien sabe si el canis lupus aureus comparte distribucion con el Lobo etiope? Deben de estar muy relacionados, no en vano son los más cercanos geográficamente y es hace relativamente poco tiempo que el Lobo Etiope se definió como especie.
Un saludo!

Re: Chacal egipcio no es un chacal, sino un lobo!
Ahora habrá que mirar toda la genética de los cánidos de la zona, Lobos, Chacales y Lobos de Simein.
Yo me he llevado una gran sorpresa con la última foto se ve un lobo (hasta ahora las fotos que he visto eran de cánidos raros), pero ojo, lo veo diferente a los lobos arábigos.
Me recuerda a los lobos rojos del sur de Norte América, aquà también hubo debate sobre la posibilidad que fuesen coyotes o hÃbrido de coyote y lobo.
Como bien dices Kaiser, osos, ciervos, zorros rojos, jabalÃs, Ãbices, etc. han conseguido desbordar el Nilo/Sinaà ¿por que no iba a hacerlo el lobo?, especie de una adaptabilidad geográfica total.
Parece mentira pero esto de la naturaleza sigue regalándonos sorpresas insospechadas.

Re: Chacal egipcio no es un chacal, sino un lobo!
A mi ese lobo se me parece mucho a un lobo ibérico, y muy poco o menos a un lobo árabe.
Todo es posible. Ya sólo queda por ver a estos lobos "eurosiberianos" cazando arruÃs en algún documental...jaja
