Those of us who want to learn about our ancestors — who they were, where they came from and how they mingled (or didn't) with others around them — often turn to historical records or elderly family members for answers. But a new study by researchers at the Stanford University School of Medicine and the University of Miami Miller School of Medicine indicates that the answers can also be found within our own genes. The researchers compared patterns of genetic variation found in...

Generation Length For Mammals Is An Essential Reference Point For Conservation Studies

Pensoft Publishers Life history traits are the basic ecological descriptors of a species. These include physical traits, such as body mass and physiological traits, such as reproductive rate. Ecologists have investigated the variation in life history traits and their role in determining the response of species to changing conditions, such as climate change, as well as to anthropogenic stressors. Generation length is one of the most studied among such traits. It represents the age at...

Bitter Taste Gene May Have Been Beneficial To Human Evolution
2013-11-12 13:31:37

Brett Smith for redOrbit.com - Your Universe Online It can be puzzling sometimes when someone else finds the taste of your favorite food to be disgusting, but research has shown we all perceive the taste of various compounds differently. A new study from researchers at the University of Pennsylvania has found a genetic mutation making certain people more sensitive to the taste of a bitter compound could have been beneficial for certain human populations in Africa, resulting in the...

Two Mouths For One Worm

Max-Planck-Gesellschaft A devious evolutionary path between genetics and environment Depending on the environment in which the worm grows, the larva of the roundworm Pristionchus pacificus develops into either a wide-mouthed predator or a narrow-mouthed bacteria eater. A team of researchers at the Max Planck Institute for Evolutionary Biology in Tübingen, Germany, headed by Ralf J. Sommer have now discovered a developmental biological switch that determines the worm's mouth form....

Butterflies Offer Insights Into Evolution
2013-10-31 16:39:31

Michael Harper for redOrbit.com - Your Universe Online A new study from the University of Chicago finds it’s genetically easier to spin off into a new species than it may have once been thought, even if the two species remain close and interbreed with one another. After studying butterflies, the researchers found evolution can happen as the result of a process rather than a single event. In fact, in the case of butterflies, the beginning of a new species could begin with something as...

Washington University in St. Louis A range of examples suggests a lack of information about their fellows can favor cooperation and prevent conflict among animals — and even among genes For the Oct. 16 issue of Biology Letters, a special issue commemorating the 50th anniversary of W.D. Hamilton’s famous paper on kin selection, two Washington University in St. Louis biologists contributed an article describing intriguing exceptions to one of his predictions. The basic idea of...
