Hasta muy recientemente, la explotación sistemática
de las aves con fines alimentarios se consideraba una característica
exclusiva de la conducta humana moderna. En cambio, algunos estudios han
dejado entrever que esto podía no ser de esta manera. En este contexto
se enmarca una investigación que ha hecho pública la revista Scientific Reportsdonde
se constata que los neandertales también habrían cazado palomas
salvajes (antepasados de los actuales) y formarían parte de su dieta.
En el trabajo ha participado Jordi Rosell, arqueólogo del IPHES e
investigador docente de la Universitat Rovira i Virgili de Tarragona.

Para
llegar a esta conclusión, un equipo internacional encabezado por Ruth
Blasco y Clive Finlayson, ambos del Gibraltar Museum, han analizado
huesos de palomas salvajes descubiertos en la cueva de Gorham
(Gibraltar), con una cronología comprendida entre los 67.000 y 28.000
años antes de ahora. Este rango de tiempo coincidió con la ocupación de
la cueva por los neandertales y, posteriormente, los Homo sapiens.
En
algunos de estos huesos -comenta Jordi Rosell-, hemos observado marcas
de corte o signos de cremación, que pueden indicar que aquellas aves
podían haber sido descuartizadas y cocinadas". "La proporción de los
huesos encontrados con marcas de corte -puntualiza el mismo arqueólogo-
fue relativamente pequeña, pero debemos tener en cuenta que este tipo de
animales requerirían una carnicería mínima y podían ser comidas
directamente con las manos. En este sentido, se han identificado marcas
de dientes humanos en algunos huesos, las cuales son una evidencia más
de que las aves fueron consumidas por los habitantes de la cueva".
Con
este trabajo, los investigadores proponen que los neandertales podrían
haber tenido habilidades similares a los humanos modernos en cuanto a la
obtención de alimentos.

Ancient pigeon bones reveal secrets of Neanderthals' bird diet
(AFP) - Neanderthals may have
caught, butchered and cooked pigeons long before modern humans became
regular consumers of bird meat, a new study has revealed.
Close
examination of 1,724 bird bones in a cave in Gibraltar revealed cuts,
human tooth marks and burns, according to research published in the
journal Scientific Reports on Thursday.
The
bones were from rock doves -- a species that typically nests on cliff
ledges and the entrance to large caves -- and the ancestors of today's
widespread feral pigeon.
The
discarded remains were dated between 67,000 and 28,000 years ago, a
period when the cave was occupied by Neanderthals and subsequently by
humans.
It was not known how
the birds were captured, though the team speculated they would have been
relatively easy to snatch from their nests "by a moderately skillful
and silent climber".
The
markings on bones from parts of the cave inhabited by Neanderthals
suggested the birds may have been butchered and cooked over fire, wrote
the researchers.
"Our results point to hitherto
unappreciated capacities of the Neanderthals to exploit birds as food
resources on a regular basis," the team wrote.
"More so, they were practising it long before the arrival of modern humans and had therefore invented it independently."
It had been thought that humans were the first to regularly eat birds.
Yet
at Gorham's Cave, "Neanderthals exploited Rock Doves for food for a
period of over 40 thousand years, the earliest evidence dating to at
least 67 thousand years ago," said the paper.
And these were not
sporadic meals, as borne out by "repeated evidence of the practice in
different, widely spaced" parts of the cave.
Other recent studies
have revealed that in addition to meat, Neanderthals ate vegetables,
berries and nuts, that they took care of their elders and used
sophisticated bone tools.
An enigmatic branch of the human family
tree, Neanderthals lived in parts of Europe, Central Asia and Middle
East for up to 300,000 years but vanished from the fossil record about
30-40,000 years ago.
Only a small proportion of bones found in the
cave's Neanderthal regions had cut marks on them, but the authors
pointed out that the birds were small and easy to eat without utensils.
"After
skinning or feather removal, direct use of hands and teeth would be the
best way to remove the meat and fat/cartilage from the bones," they
wrote.
"The proof of this is the human toothmarks and associated damage observed on some dove bones."
They conceded the scorch marks were not conclusive proof of cooking, but could also be waste disposal or accidental burning.
