Indirect support for these claims has also came from a recent study (Patterson, N., Richter, D. J., Gnerre, S., Lander, E. S. & Reich, D. (2006), Genetic evidence for complex speciation of humans and chimpanzees, Nature 441:1103-1108), where it is suggested that the separation between the chimp and humans lineages was far from a "clean" speciation event, involving gene exchanges a long time (millions of years) after their "separation".
Another interesting twist came very recently with a preliminary anouncement concerning the sequencing of Neandertal nuclear DNA (as opposed to just mtDNA) - see, for example the review in Pennisi, E. (2006), The dawn of stone age genomics, Science 314:1068-1071. One of the teams involved (the Max Planck Institute for Evolutionary Anthropology in Leipzig) seems to have found some hints of admixture (but everything is still preliminary). As S. Pääbo puts it: "Taken at face value, our data can be exaplained by gene flow from modern humans into the Neandertals" (cited in Pennisi, 2006:1070), suggesting, thus a directional geneflow. However, until more reliable data and details on the techniques and associated risks (contamination, decay, etc.) are available, one must refrain from speculating too much.
