This is turning into a big story - see http://phys.org/print301240629.html ... the discovery of early human skulls in Georgia (in the Transcaucasus) which have been dated 1.8 million years ago, but surprisingly were found under medieval buildings, suggest the human family tree is not as varied or as lengthy as the consensus believes. The article is published in Science journal and requires reading in full before making lame assertions but the idea being explored is that Homo Erectus varied as far as shape, size, and type are concerned - but it must be emphasized, others disagree.
This question comes up all the time. What actually happened around 40,000 years ago. The old chestnust that Neanderthals were conservative in their diet no longer holds true - from a variety of evidence from different sites (but see http://phys.org/print298626001.html). A cave in the Caucasus mountains suggests Neanderthals were eating fish - or so it is theorised. It is assumed the fish were brought to the cave by humans for consumption - how else might they have got there. How else indeed.
Not the very modern humans but those that were around 40,000 years ago - see www.sciencedaily.com/releases/2013/09/130913093314.htm

Scientists from Liverpool John Moores University and the University of Nottingham have published their analysis of one of the sets of bones in Journal of Quaternary Science.

Modern leather workers still use similar tools - but these date 50,000 years ago. Bone tools have often been associated with Neanderthals in the past but the association has been denied as the deposits, usually found above the Neanderthal layers, has led to the accusation that the tools really belong to modern humans and have somehow penetrated into the lower Neanderthal levels.
At http://johnhawks.net/weblog/reviews/archaeology/upper/india/mishra-micro... ... is a discussion of a paper by Sheila Mishra et al which centres on the introduction of micro blade tool assemblages in India, and their possible association with an actual human migration, focussing on one site in particular in Madhya Pradesh (and now dated around 45,000 years ago). John Hawks is his usual sceptical self and uses it to discuss the Late Pleistocene in India.

Is it possible that migrations are also older than imagined - such as the genetic footprint of the first farmers. Might this mark the genetic footprint of a Palaeolithic migration - or is this pie in the sky.
At www.geneticarchaeology.com/research/Did_Neandertals_have_language.asp ... we learn that research seems to suggest Neanderthals were very similar to modern humans, in a variety of ways. The idea Neanderthals, or Homo erectus come to that, were completely different to modern humans is all down to scholarly classification - which box, or museum drawer a particularly skull might be stored away. Classification led to the idea modern humans are in some way special, rather clever creatures and therefore quite unlike their forebears.
On a day that a video has been published of a beheading of three Christian monks or Catholic priests in Syria by the very people some of our politicos want to get into bed with, and supply them with the arms to liberate Christian establishments by killing them all with kitchen knives, there is a story about Syrian Christians in Egypt at www.pasthorizonspr.com/index.php/archives/06/2013/deir-al-surian-a-treas... ... a geological depression west of the Nile delta was a cradle of Coptic monasticism going back to the 4th century AD.

The paper seems to imply they did not record what they could see but only what they believed as a result of their mythology. Perhaps they were also wearing blindfolds when they climbed up rock faces to make etchings in difficult locations.
