Anthropologists working with the recently discovered remains of a 1.8 million year old human have begun reaching some startling conclusions regarding the diversity of the human form at that point in our evolution. What have been hitherto presumed to have been separate human species now appear to actually have been simply very different but completely contemporary members of the one species, Homo Erectus. This video from The Guardian introduces the topic:

That should start a right good stair heid rammy amongst the paleo-anthropologists, they're an argumentative and vitriolic bunch. The Johanson-Leaky feud over Lucy's family was a doozy. A lot of territories will now be defended with the vigour of bull elephant seals.
Talking of Johanson, didn't he originally think that the Hadar au. africanus specimens were different species until he was persuaded that the differences were due to sexual dimorphism?

I've had a look at the Science article and the argument seems persuasive, at least to one who isn't au fait with the a lot of it; there's another more detailed illustration of the 5 skulls drawn from different aspects and the variety of size, shape, jaw robustity and brain case size is striking. The main problem in deciding whether or not these and the African homos are all of the same species, I suppose, is the paucity of examples of, say, h. rudolfensis which does, it must be said, look very different to the Dmanisi skulls. Maybe he ran into a rock face while getting away from a big cat.

Whoever is right, I wouldn't want to argue with no 5, he's a scary looking dude.

Yes, Ferval, some different thoughts from different sides...
Saw this evening on the BBC world site:
http://www.bbc.co.uk/news/science-environment-24564375

And yes Temperance, I too see a hallo around the name of our most distinguished leader...

Kind regards and with esteem to both,

Paul.

Paelontologists are divided into two species, "lumpers" who regard all contemporary fossils as being of one species, and "splitters" who will postulate a new species (especially if they have discovered it) for any new discovery which isn't virtually identical to existing ones. Professoris dmanisianus is obvously a representative of the "lumper" tendency.

Discovery of a jaw bone in Ethiopia has pushed the date for the earliest human back by 400,000 years;

For a given value of the term "human" - I don't reckon that one is "Homo", rather another Australopithecine - possibly a new species, more likely just an early member of one of the known ones.

Triceratops,

beaten in the spurt...
I wanted just to start a thread about:

Human like footprints in Crete:

Cretian Footprints

HUMAN-like footprints have been found on an ancient sea shore. They shouldn’t be there. They’re in the wrong place at the wrong time.

The key word would appear to be human-LIKE, they may not even have been made by hominids ... crucially the prints also do not seem to show a deep heel-print which is one of the signatures of a truely human-like bipedal gait.

Which in turn begs the question, what did make the tracks?

Or a descendent of this chap, the 7 million-year old Graecopithicus from Northern Greece and Bulgaria:



... or their dating is a bit out.

Interesting nevertheless.

PS : I take that reconstruction of Graecopithicus to be anatomically correct, as least as far as one can be sure given the paucity of remains, but for a 7 million-year-old hominid it does look remarkably "non-primitive". The face at least would not raise many eyebrows were he to be sat on public transport. Indeed I once dated a guy who looked very much like that ... hairy and often rather unshaven, and very, very  muscular ... but although amiable and pleasant, he was not, intellectually, the sharpest handaxe in the basket.

Isn't it just amazing what can be deduced from this..........



If you dressed that reconstruction in an old oil stained vest he would be the very image of a fisherman we met in Thassos in the early 70s.

Yes, yes, Meles meles you too have a history...and a rich one... Wink

Kind regards from your friend Paul, not that hairy, muscular and so on one...

PS: Couldn't resist, it was starker than myself...
PPS: But murderers said the same...

We all, every one of us, have our history, Paul.

Although strictly don't family tales only really become 'history' once they've been reliably written down, otherwise they're still just 'anecdotes'. But apologies to the OP, we're straying away from the subject and dem old bones.
