"There is little doubt that this haplotype is present because of mating with our ancestors and Neanderthals. This is a very nice result, and further analysis may help determine more details," says Dr. Nick Patterson, of the Broad Institute of MIT and Harvard University, a major researcher in human ancestry who was not involved in this study.
"Dr. Labuda and his colleagues were the first to identify a genetic variation in non-Africans that was likely to have come from an archaic population. This was done entirely without the Neanderthal genome sequence, but in light of the Neanderthal sequence, it is now clear that they were absolutely right!" adds Dr. David Reich, a Harvard Medical School geneticist, one of the principal researchers in the Neanderthal genome project.
So, speculates Dr. Labuda, did these exchanges contribute to our success across the world? "Variability is very important for long-term survival of a species," says Dr. Labuda. "Every addition to the genome can be enriching." An interesting match, indeed.
Recent work on the Neandertal genome has raised the possibility of admixture between Neandertals and the expanding population of H. sapiens who left Africa between 80 Kya and 50 Kya to colonize the rest of the world. Here we provide evidence of a notable presence (9% overall) of a Neandertal-derived X chromosome segment among all contemporary human populations outside Africa. Our analysis of 6092 X-chromosomes from all inhabited continents supports earlier contentions that a mosaic of lineages of different time depths and different geographic provenance could have contributed to the genetic constitution of modern humans. It indicates a very early admixture between expanding African migrants and Neandertals prior to or very early on the route of the out-of-Africa expansion that led to the successful colonization of the planet.
http://www.ted.com... We're not done with anatomy. We know a tremendous amount about genomics, proteomics and cell biology, but as Diane Kelly makes clear at TEDMED, there are basic facts about the human body we're still learning. Case in point: How does the mammalian erection work?

I, a female, was enjoying my learning experience while reading and watching through this entire post when I was suddenly ground to a halt by Helen's seemingly curt and sarcastic reply to Bill's moving of comments. I find the philosophy of sexuality to be extremely important and on topic. I had intended, when I got to the end, to thank Terry for all the wonderful information he has posted about sexuality and the science and philosophy of sexuality. Instead I find myself very much on the defensive. IMO, the thread is clearly marked as sexual content so you can choose whether to read or not.
Now, Terry, Thank you so much for all the great information!
A joke below which highlights our revenge as fundamental moral system, 'love' as a thing to be cherished and 'love' used as a tool to harm.
And, then also, the joke understands the creative punitive understanding learned by children on how they to may be punitive against others to get what they want.

The Lemmy Joke
Motörhead ( /ˈmoʊtərhɛd/) are an English heavy metal band formed in 1975 by bassist, singer and songwriter Ian Fraser Kilmister, known mainly by his stage name Lemmy, who has remained the sole constant member.
The band is often considered a precursor to or one of the earliest members of the New Wave of British Heavy Metal, which re-energised heavy metal in the late 1970s and early 1980s. Usually a power trio, Motörhead had particular success in the early 1980s with several successful singles in the UK Top 40 chart.
The albums Overkill, Bomber, Ace of Spades, and particularly No Sleep 'til Hammersmith, cemented Motörhead's reputation as one of Britain's foremost rock bands.
Written and directed by MEF Executive Director Sut Jhally, The Codes of Gender applies the late sociologist Erving Goffman's groundbreaking analysis of advertising to the contemporary commercial landscape, showing how one of American popular culture's most influential forms communicates normative ideas about masculinity and femininity.
In striking visual detail, The Codes of Gender explores Goffman's central claim that gender ideals are the result of ritualized cultural performance, uncovering a remarkable pattern of masculine and feminine displays and poses. It looks beyond advertising as a medium that simply sells products, and beyond analyses of gender that focus on biological difference or issues of objectification and beauty, to provide a clear-eyed view of the two-tiered terrain of identity and power relations.
With its sustained focus on how our perceptions of what it means to be a man or a woman get reproduced and reinforced on the level of culture in our everyday lives, The Codes of Gender is certain to inspire discussion and debate across a range of disciplines.

Gender Advertisement refers to the images in advertising that depict stereotypical gender roles and displays. Gender displays are used heavily in advertising in order to establish the role of one gender in relation with the other, and some scholars argue that advertisers are obsessed with gender. However, unlike sex which is the product of biologically based male-female difference; gender is not natural but rather a sociocultural construction which refers to the relationship between men and women or femininity and masculinity. It is this relationship that advertisers are obsessed with, because people define themselves by gender, and gender can be “communicated at a glance,” making it easy for advertisers to use this theme in their work.
All of us have some sort of "philosophy of life," even though we may not have verbalized it. Here you can get ideas for your own philosophy of life. You can see what others think of your own philosophical ideas, and you can help others to become clearer in their own thinking.
When there is difference of opinion, we have an opportunity for "friendly debate," a very growth-promoting experience.
