View Full Version : Giant lion-eating chimps found in Congo

Deep in the Congolese jungle is a band of apes that, according to local legend, kill lions, catch fish and even howl at the moon. Local hunters speak of massive creatures that seem to be some sort of hybrid between a chimp and a gorilla.

Their location at the centre of one of the bloodiest conflicts on the planet, the civil war in the Democratic Republic of Congo, has meant that the mystery apes have been little studied by western scientists. Reaching the region means negotiating the shifting fortunes of warring rebel factions, and the heart of the animals' range is deep in impenetrable forest.

But despite the difficulties, a handful of scientists have succeeded in studying the animals. Early speculation that the apes may be some yeti-like new species or a chimp/gorilla hybrid proved unfounded, but the truth has turned out to be in many ways even more fascinating. They are actually a population of super-sized chimps with a unique culture - and it seems, a taste for big cat flesh.

The most detailed and recent data comes from Cleve Hicks, at the University of Amsterdam, who has spent 18 months in the field watching the Bili apes - named after a local town - since 2004. His team's most striking find came after one of his trackers heard chimps calling for several days from the same spot.

When he investigated he came across a chimp feasting on the carcass of a leopard. Mr Hicks cannot be sure the animal was killed by the chimp, but the find lends credence to the apes' lion-eating reputation.More here (http://environment.guardian.co.uk/conservation/story/0,,2126328,00.html)

No, that kinda sucks...

I couldn't find anything on the UvA (University of Amsterdam) site either.

I wouldn't want them living next door to me. :unnope:

Dingfod's picture and the one below are particularly interesting:

Chimps don't have prominent sagittal crests, but gorillas do and so did early hominids such as the members of the genus Australopithecus. (Chimps are much more closely related to us than they are to gorillas, so it would be imprecise to say that these apes are "evolutionarily intermediate" between chimps and gorillas -- if anything, it might be more accurate to say they're intermediate between us and "regular" chimps.)


Anyway, if a prominent sagittal crest is a normal feature of these "Bili Mystery Apes," it might well turn out that they're best considered to be a separate species from either Common Chimps (Pan troglodytes) or Bonobos (Pan paniscus). It'll be interesting to see where genetic analyses place them in relation to other chimps and to humans.

Don't get me wrong; I'm not suggesting they're more closely-related to humans than are the other two chimpanzee species. They almost certainly are not. Rather, it may turn out that, after the hominid/chimp lineages split, the chimpanzee lineage produce 3 distinct species rather than just 2. (Or maybe more, but 3 are still surviving.) After all, the hominid lineage produced numerous species, though only one survives today.

So, even if these "Bili Mystery Apes" turn out to be a separate chimp species, they wouldn't be any more closely-related to us than are the other two chimp species. On the other hand, the fact that both early hominids and these "Mystery Apes" had/have sagittal crests implies that the crests are an ancestral feature that was independently lost both in modern hominids and in (most) modern chimpanzees.

That's not surprising -- gorillas retain sagittal crests too, which lends further support to the conclusion that sagittal crests are an ancestral trait that has been lost in some ape lineages. Sagittal crests provide increased area for attachment of jaw muscles, and therefore allow a much more powerful bite. For gorillas, this allows them to tackle tough nuts and woody vegetation that few other animals can process. That might be the case for these "Mystery Apes" as well -- or it might be that the more powerful jaws allow for effective killing of animal prey as well. (Lions and other obligative carnivores have well-developed sagittal crests as well, giving them powerful bites for dispatching prey.)

Interesting stuff!

Cheers,

hmm.. however that link led me to this site (http://www.karlammann.com/gallery-bushmeat.php).

I think I'm going to be ill. I also think I'll be eating less meat than I already do. :vomit:
