...study published in the August 7 issue of Science, vulnerability to extinction runs in families, meaning that some groups of species have a higher likelihood of becoming extinct than others. "It turns out that some branches of the tree of life are more extinction-prone than others," says Kaustuv Roy, a biology professor at the University of California, San Diego. "Those traits aren't just a part of extinctions that human beings cause, but a general feature of extinction itself." (See the world's endangered species...
...Roy and his colleagues at the Smithsonian Institution and the University of Chicago examined 200 million years of history of marine clams, oysters and mussels; they picked the simple bivalves because they have a long and detailed fossil record. Going back to the Jurassic period, researchers analyzed when each genus - a taxonomic category just above species - disappeared, and whether relatives vanished at the same time. On average they found that closely related groups of clams went extinct together at a rate that was more often than expected by blind chance - generally those groups of species were confined to a fairly...
...much richer evolutionary history, because at least some representatives of all living things would make it to the present. But because extinction tends to be clumped around certain lineages, when extinction occurs we lose whole groups of species. "The long-term consequences are therefore much worse for biodiversity," says Roy...
...Focusing on the symbolic power of money, the study's authors, Xinyue Zhou of Sun Yat-Sen University, Kathleen Vohs of the University of Minnesota and Roy Baumeister of Florida State University, started with a simple hypothesis: reminders of money can alter how people experience social interactions - especially social acceptance and rejection.

...bias against Israel is well documented. Her review of the book Hamas: Politics, Charity, and Terrorism in the Service of Jihad was rejected by Tufts University’s Fletcher Forum on World Affairs as “all reviewers found the piece one-sided.” Ms. Roy ignores the major source of Gaza’s tragic situation: Hamas, internationally recognized as a terrorist group whose military power is growing thanks to abundant support from the Iranian regime. Since 2006, when Hamas won Gaza’s elections, it has failed to fulfill any of the promises...
