This may not be brand new, but I find it funny here and there.

Long “interbreeding” between man and chimpanzee
Man's ancestors and chimpanzees would have crossed during millenia if not million years, before a final separation, much more recent than one thought, according to a study published online on Wednesday by Nature.
According to this work, undertaken by American researchers under the direction of David Reich, from Medical Harvard School in Boston (Massachusetts), the two breeds initially separated 6,3 million years ago at most, and probably less than 5,4 million years ago, but that did not prevent them from carrying out exchanges of genes.
That, as scientists specify, is particularly perceptible in X chromosomes (female chromosomes)*, which similarities seem to reflect a long “de-hybridization” between the two breeds. The final “divorce” would have only occured in the end of a long period of “interbreeding” which perhaps lasted 4 million years.
“The study gave unexpected results as for the way in which we separated from our closest parents, chimpanzees. We noticed that the structure of the population which existed around the period of this speciation (appearance of new species) was different from any modern monkey population. Something very particular had to occur at this time”, David Rech summarizes in an official statement accompanying the scientific text.
The results question the statute of Hominides considered as man's oldest ancestors , such as the sahelanthrope (alias "Toumaï"), a man from 6 to 7 million years, Orrorin (known as “the ancestor of the millenium”) [...] [I cut it, it's boring]
In addition, the complete sequencing of the genome of chimpanzees did not bring the discounted indications either . While accumulating a considerable amount of data, the collective work, which was published last year, confirmed what was already suspected: the two species are genetically identical to 99%, without making it possible to define in precise terms the specificity of man.**
The geneticists thus remained vague while noticing that the genetic differences between man and chimpanzees are sixty times less numerous than those that distinguish us from mice, and that between a human being and a chimpanzee this number is ten times as big as what distinguishes two individuals from our own species.
* Then women certainly got more involved in monkey sex, didn't they?
** In other words, scientists cannot precisely tell the difference between man and chimps...
