Insects Evolved Radically Different Strategy to Smell

Darwin's tree of life represents the path and estimates the time evolution took to get to the current diversity of life. Now, new findings suggest that this tree, an icon of evolution, may need to be redrawn. 
Functional protein divergence in the evolution of Homo sapiens
davidd submitted, created time 10 months 3 weeks (genomebiology.com)
Protein-coding regions in a genome evolve by sequence divergence, and gene gain and loss, altering the gene content of the organism. However, it is not well understood how this has given rise to the enormous diversity of metazoa present today. In order to obtain a global view of human genomic evolution, they quantify the divergence of proteins by functional category at different evolutionary distances from human.
Team Uncovers New Evidence of Recent Human Evolution

By identifying 582 genes that have evolved differently in different populations in the past 60,000 years, including a dozen that protect people from obesity, diabetes, hypertension, and other diseases, researchers have found powerful new evidence of recent human evolution.
Evolution of Counting Is No Simple Operation

You may not realize it, but when you tell the grocer you'd like a half-dozen eggs for your family of six, you're using a primitive numbering system.
Now, a study of Pacific Island languages suggests that counting systems can evolve in reverse, becoming more object-specific.

Evolution cause Mom in a Full, Upright Position
Eric wu submitted, created time 1 year 3 weeks (sciencenow.sciencemag.org)
Gravity is not kind to the pregnant woman. With 7-plus kilograms added to her tummy, a soon-to-be mother must stretch her lower back to balance the bulge. Now, a study suggests that women's spines evolved to help them carry the extra weight. The findings show how the need to reproduce can drive evolution, say the authors, but some scientists argue that the changes in the spine stem from an already well-explained phenomenon.
How women bend over backwards for baby

Researchers have found that the vertebrae that make up a woman’s spine have evolved to give her more support, probably to help her cope during pregnancy. The results hold true for modern mothers as well as those of their ancient ancestors, Australopithecus, who lived more than two million years ago. Vertebrae in men lack these features.
Human Evolution Is Speeding Up
Eric wu submitted, created time 1 year 4 weeks (sciencenow.sciencemag.org)
Plentiful food has made it easier than ever before to survive and reproduce in many parts of the world, so it's tempting to think that our species has stopped evolving. But a controversial new study says that isn't so. Far from slowing down, human evolution has sped up in the past 40,000 years and has become 100 times faster in the past 5000 years alone, according to the analysis. This means that even though some people have been globe-trotters who interbreed, most humans on different continents are becoming more different, rather than blending together into one genetically homogenous race.
Human Ancestor Preserved in Stone

A hugely important discovery was found by workers at a travertine factory near Denizli, Turkey. They sawed a block of the limestone for tiles and discovered part of a human skull. Researchers says that it appears to be a long-sought species of human that lived 500,000 years ago, however, the fossil also reveals the earliest case of tuberculosis (TB).
TB's presence might provide clues about what this early human looked like and how it adapted to new habitats
It's No Delusion: Evolution May Favor Schizophrenia Genes
wugongliang submitted, created time 1 year 1 month (www.sciam.com)
Schizophrenia, the psychotic disorder marked by hallucinations, delusions and cognitive disorganization, affects roughly 1 percent of the U.S. population.* Many of those afflicted, however, also have reduced reproductive fitness, which means they are less likely to pass a genetic profile associated with the condition onto their offspring.
Scientists unearth 'missing link' jawbone
jane2007 submitted, created time 1 year 1 month (www.theregister.co.uk)
Scientists are postulating that a 10 million year old jawbone unearthed in Kenya's northern Nakali region may belong to the so-called evolutionary "missing link" - the common ancestor of African great apes and humans.
New Ape Fossils Found in Africa
Eric wu submitted, created time 1 year 1 month (sciencenow.sciencemag.org)
Fossil hunters exploring the eastern edge of the Rift Valley of Kenya have found the jawbone of a 10-million-year-old ape that appears to be a close relative of the last ancestor of humans, chimpanzees, and gorillas. The discovery of this ancient ape strikes a new blow against a theory that apes in Africa died out millions of years ago only to be replaced by other apes that had migrated to Europe and Asia and then returned.(This news described the finding of new ape fossils and other questions on them.It may be usefull for archaeologists.So I recommend the article.)
Study on strippers reveals evidence of human estrus.
Darkfrog submitted, created time 1 year 2 months (www.ehbonline.org)
Unlike most mammals, which have an estrus cycle -- they go into heat, during which they give off detectable visual and chemical signs of fertility -- humans have a menstrual cycle. For many years, scientists had assumed that our little sniffers had lost the ability to pick up on anything more subtle than an overdose of Axe. However, a study performed on eighteen eager ecdysiasts found that they get about half again as much in tips while ovulating than they do during the leuteal phase, and twice as much as they do during menstruation

A Canadian scientist has published a provocative study that predicts decreasing fertility rates in developed countries will reverse their decades-long trend and the "maternal instinct" will naturally return. In short, he argues, Darwinism should eventually doom the DINKs -- the "Double Income, No Kids" category of popular demographics.
The Majority of Recent Short DNA Insertions in the Human Genome Are Tandem Duplications

"As is already well established in the context of gene and segmental duplications, our results demonstrate that duplications are also likely to constitute the predominant process for rapid generation of new genetic material and function on smaller scales. "

"An ambitious project that promises to extend humanity's view of itself.
“NO MAN is an island,” wrote John Donne. He was thinking of the wider society of which every human being is a member, but it is also true that human bodies themselves are societies. Besides the 10 trillion human cells in a body, there are another 100 trillion bacterial cells
