Given the relative paucity of ova and plenitude of sperm, as well as the unequal feeding duties that fall to women, men invest less in children. Therefore, men should be expected to be less discriminating and more aggressive in competing for females. It was an elegant, powerful application of evolutionary theory to the mating game. In , David M. Buss and David P. Promiscuity, the researchers hypothesized, would have been more damaging to the female reputation than to the male reputation. If a man mated with a promiscuous woman, he would never be able to ensure his paternity. Men, on the other hand, could potentially enhance their status by pursuing a short-term mating strategy.
Hacking Your Genes Has Never Been Easier
Intelligence is believed to be among the conditioned genes that have to come from the mother. Laboratory studies using genetically modified mice found that those with an extra dose of maternal genes developed bigger heads and brains, but had little bodies. Those with an extra dose of paternal genes had small brains and larger bodies.
Researchers identified cells that contained only maternal or paternal genes in six different parts of the mouse brains which controlled different cognitive functions, from eating habits to memory.
Indeed, when surveyed for attributes in selecting a mate, both males and females felt kindness and an exciting personality were more important in a mate than good looks.
Now a study of the maternal genes of skeletal and mummified remains of 92 South Americans dating from 8, to years ago shows that all those lineages were wiped out. No living person descended from any the individuals tested is known to be living today. It is unknown how many people lived in the Americas when Columbus and the other conquistadors arrived. Estimates range from 1 million to million. One middling estimate puts the North American number alone at about 12 million people, who were reduced to , by Of the 84 genetic lineages among the 92 South American remains, not one lineage survived contact with Europeans, a new study says.

Link Meditate on health What researchers at Harvard Medical School discovered is that, in long-term practitioners of relaxation methods such as yoga and meditation, far more ”disease-fighting genes” were active, compared to those who practised no form of relaxation. In particular, they found genes that protect from disorders such as pain, infertility, high blood pressure and even rheumatoid arthritis were switched on.
The changes, say the researchers, were induced by what they call ”the relaxation effect”, a phenomenon that could be just as powerful as any medical drug but without the side effects.

Samaritan sources[ edit ] According to Samaritan tradition, Mount Gerizim was the original Holy Place of the Israelites from the time that Joshua conquered Canaan and the tribes of Israel settled the land. The two mountains were used to symbolize the significance of the commandments and serve as a warning to whoever disobeyed them Deut.
Samaritan historiography places the basic schism from the remaining part of Israel after the tribes of Israel conquered and returned to the land of Canaan , led by Joshua. In its account, after Joshua’s death, Eli the priest left the Tabernacle which Moses erected in the desert and established on Mount Gerizim and built another one under his own rule in the hills of Shiloh.
Abu l-Fath , who in the 14th century wrote a major work of Samaritan history, comments on Samaritan origins as follows: He used to offer sacrifices on an altar of stones. He was 50 years old, endowed with wealth and in charge of the treasury of the Children of Israel. He offered a sacrifice on the altar, but without salt, as if he were inattentive.
When the Great High Priest Ozzi learned of this, and found the sacrifice was not accepted, he thoroughly disowned him; and it is even said that he rebuked him.

At a time when single men around the world have been passionate by the wave of acquaintances through the Internet with brides from Russia and the term mail order brides becoming a symbol of the era, not many women from the former USSR were separated from Russian and Ukraine. But that is in vain. For all the similarities in characters the difference between girls from FSU is enormous.
What is it, beauty? Southern Europe is famous for the beautiful and temperamental ladies. Italians, Spaniards, and Russian wives are certainly attractive and sexy, but their beauty cannot be compared with the exquisite natural charm and natural beauty of the girls from our country. No country in the world will you find so many cute, slim and smiling women on the streets as in Ukraine. Do you not believe me? Just take a stroll through the streets of most southern Ukrainian cities such as; Odessa , Nikolayev , and Kherson where you need look no further.
Blondes , brunettes , redheads and brown haired, for an hour you will meet hundreds of Ukrainian beauties, even in real everyday life. They are caring mothers and excellent hostesses.

Dressed like a decent human being …Khmer women will treat you like a king. You just have to come to Cambodia. In fact, I was shocked at how many girls stared at me. Street hookers are everywhere.
Beauty beyond symmetry However, John Manning of the University of Liverpool in England cautions against over-generalization, especially by Western scientists.
The tables are scattered with pipettes and disposable blue gloves, cases of Red Bull and Slim Jims are near at hand, and Drake is pulsing on the sound system. But no jellyfish were harmed in the making of this beer. The process is shockingly easy. Download the Audm app for your iPhone to listen to more longform titles. I raise my glass and pause. I have no idea which species of jellyfish the GFP gene came from, but my hunch is that it has never been a regular part of the human diet.
Scientists have engineered glowing cats and mice using GFP, he points out, and the creatures lived just fine. For what he would call a science experiment and I would call conceptual art, he removed dead skin cells from his forearm just rub the same spot with a toothbrush times and used a tattoo needle to punch jellyfish DNA into his skin. The DNA was attached to a common virus that specializes in infiltrating human cells and parking itself there.
He also performed a DIY fecal transplant on himself, which was chronicled in the recent documentary Gut Hack , curing himself of years of irritable bowel syndrome. Just like that, this crunchy Vermonter who always shunned GMOs filled his belly with them, and starts looking forward to the week ahead. Extracting the DNA from life forms and inserting it into other life forms seemed like the kind of thing that required high-tech machines and years of trial and error.

In ancient Greece, Helen of Troy, the instigator of the Trojan War, was the paragon of beauty, exuding a physical Model Cindy Crawford, an example of symmetry Image courtesy of www. Indeed, she was the toast of Athens, celebrated not for her kindness or her intellect, but for her physical perfection. But why did the Greek men find Helen, and other beautiful women, so intoxicating?
In an attempt to answer this question, the philosophers of the day devoted a great deal of time to this conundrum.

Many believe love is a sensation that magically generates when Mr. No wonder so many people are single. A few years ago, I spoke to a group of high-schoolers about the Jewish idea of love. I’ll define it, and you raise your hands if you agree. Love is that feeling you get when you meet the right person. And I thought, Oy. This is how many people approach a relationship. Consciously or unconsciously, they believe love is a sensation based on physical and emotional attraction that magically, spontaneously generates when Mr.
And just as easily, it can spontaneously degenerate when the magic “just isn’t there” anymore.

Monica meanwhile chose an equally bold and bright dress, showcasing her figure in a neon bright animal print number teamed with black heels.
During the First Temple, it was possible for foreigners to help the Jewish people in an informal way until tension grew between the Samaritans and Judeans.
Despite large geographic distances between the communities and the passage of thousands of years, far removed Jewish communities share a similar genetic profile. This research confirms the common ancestry and common geographical origin of world Jewry. Jewish men from communities which developed in the Near East —- Iran, Iraq, Kurdistan, Yemen — and European Jews have very similar, almost identical genetic profiles.
The results support the hypothesis that the paternal gene pools of Jewish communities from Europe, North Africa and the Middle East descended from a common Middle Eastern ancestral population, and suggest that most Jewish communities have remained relatively isolated from neighboring non-Jewish communities during and after the Diaspora. Nat’l Academy of Science, May 9, The basis of this new field of population research is the study of the Y-chromosome, which is passed virtually unchanged from father to son.
The rare mutations -— which are changes in the non-coding portion of its DNA —- can serve as markers, which can distinguish peoples. By studying the genetic signatures of various groups, comparisons can be made to determine the genetic relationships between the groups. Y-chromosome research of the Jewish people began as an outgrowth of the study of Cohanim —- the Jewish priestly family.
These studies showed a very high genetic affinity among present-day Cohanim, indicating that they do have a common paternal ancestor, estimated to have lived some 3, years ago. This genetic anthropology promises to be particularly informative for tracking the history of Jewish populations, and helping to resolve the debate on the origins and migrations of Jewish communities in the Diaspora.
