'Neanderthals mated with some modern humans after all and left their imprint in the human genome, a team of biologists has reported in the first detailed analysis of the Neanderthal genetic sequence.
The biologists, led by Svante Paabo of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, have been slowly reconstructing the genome of Neanderthals, the stocky hunters that dominated Europe until 30,000 years ago, by extracting the fragments of DNA that still exist in their fossil bones. Just last year, when the biologists first announced that they had decoded the Neanderthal genome, they reported no significant evidence of interbreeding.
Scientists say they have recovered 60 percent of the genome so far and hope to complete it. By comparing that genome with those of various present day humans, the team concluded that about 1 percent to 4 percent of the genome of non-Africans today is derived from Neanderthals. But the Neanderthal DNA does not seem to have played a great role in human evolution, they said.' - http://www.nytimes.com/2010/05/07/science/07neanderthal.html
Timeline
1829: Neanderthal skulls were discovered in Engis, Belgium.
1848: Neanderthal skull found in Forbes' Quarry, Gibraltar. Called "an ancient human" at the time.
1856: Johann Karl Fuhlrott first recognised the fossil called "Neanderthal man", discovered in Neanderthal, a valley near Mettmann in what is now North Rhine-Westphalia, Germany.
1880: The mandible of a Neanderthal child was found in a secure context and associated with cultural debris, including hearths, Mousterian tools, and bones of extinct animals.
1886: Two nearly perfect skeletons of a man and woman were found at Spy, Belgium at the depth of 16 ft with numerous Mousterian-type implements.
1899: Hundreds of Neanderthal bones were described in stratigraphic position in association with cultural remains and extinct animal bones.
1908: A nearly complete Neanderthal skeleton was discovered in association with Mousterian tools and bones of extinct animals.
1953–1957: Ralph Solecki uncovered nine Neanderthal skeletons in Shanidar Cave in northern Iraq.
1975: Erik Trinkaus's study of Neanderthal feet confirmed they walked like modern humans.
1987: Thermoluminescence results from Israeli fossils date Neanderthals at Kebara to 60,000 BP and humans at Qafzeh to 90,000 BP. These dates were confirmed by electron spin resonance (ESR) dates for Qafzeh (90,000 BP) and Es Skhul (80,000 BP).
1991: ESR dates showed the Tabun Neanderthal was contemporaneous with modern humans from Skhul and Qafzeh.
1997: Matthias Krings et al. are the first to amplify Neanderthal mitochondrial DNA (mtDNA) using a specimen from Feldhofer grotto in the Neander valley.[21]
2000: Igor Ovchinnikov, Kirsten Liden, William Goodman et al. retrieved DNA from a Late Neanderthal (29,000 BP) infant from Mezmaikaya Cave in the Caucasus.[22]
2005: The Max Planck Institute for Evolutionary Anthropology launched a project to reconstruct the Neanderthal genome.
2006: The Max Planck Institute for Evolutionary Anthropology announced it planned to work with Connecticut-based 454 Life Sciences to reconstruct the Neanderthal genome.
2009: The Max Planck Institute for Evolutionary Anthropology announced the "first draft" of a complete Neanderthal genome is completed.[23]
2010: Comparison of Neanderthal genome with modern humans from Africa and Eurasia show modern non-African humans have 1–4% Neanderthal DNA

OMG! Did they ask Raymond for a sample of his DNA? It could explain alot.

Hey Maggie
How you feeling, any better?

Yeah, you are probably right, but somehow it feels true.

Yuck you smoke? Sorry to hear that you smoke. I quit after about 30 years so anyone can do it. No wonder you are sick.

Get a room! LOL

Quit crying and instead quit smoking. It is easy, a piece of cake. How many years have you smoked?
The love thing I already told you what to do.
LMAO
Peace
