Cannibalism
Linked to Mad Cow Disease
Cannibalism in
ancient times may have caused epidemics of brain destroying diseases like Kuru
and Creutzfeld Jacob disease, a team of British researchers suggest.
Those two diseases and the
human form of mad cows disease are believed to be caused by prions, an abnormal
protein missing nucleic acid that can cause proteins to clump in the
brain.
The disease can be spread by
eating flesh contaminated with prions.
Some people have gene
mutations that protect them from those illnesses.
The research team led by
John Collinge of University College in London, reported in Friday’s issue of the
journal Science that the protective genes, called polymorphisms, are mutant
versions of prion protein gene and show signs of having spread through the
population through natural selection.
“What we’re showing here is
evidence that selection for these polymorphisms has been very wide spread or
happened very early on in the evolution of modern humans, before human beings
spread all over the planet,” Collinge said in a statement. “We can’t say which
of those it is; but the obvious implication is that prion disease has provided
the selection pressure.”
Suggesting that cannibalism
could have spread the diseases, increasing pressure to develop protective genes,
the study cites the Fore people of Papua New Guinea, who were devastated by an
epidemic of prion disease Kuru between 1920 and 1950.
It was there practice at
mortuary feasts to consume diseased relatives until cannibalism was banned in
the 1950s.
Collinge studied 30 women
that had participated in these feasts and still living, and found 23 had the
genetic variation that protects against Kuru.
It’s the same genetic
variation that helps protect against Creutzfeld Jacob disease, the study noted
and the human form of mad cow disease is known as new variant Creutzfeld Jacob
disease.
“There is extensive
anthropological evidence that cannibalism is not just a rarity that happened in
New Guinea,” Collinge said.
Other evidence of
prehistoric cannibalism includes cuts and bruising marks on Neanderthal bones
and biochemical analysis of human faeces.
Giuseppe Legname, a prion
disease researcher at University of California, San Francisco, called the paper
intriguing but said he would like to see data from a larger population
sample.
“We know – that some
polymorphisms make people resistant to prion diseases,” he said. “But we need to
learn more before we can drawer any conclusions.”
As far as cannibalism goes,
he added, “that’s something interesting. We don’t have much information about
prehistoric times and what were our ancestors’ habits.”
