Biologists explain how organisms can tolerate mutations, yet adapt to environmental change (1/24/2010)

Biologists at the University of Pennsylvania studying the processes of evolution appear to have resolved a longstanding conundrum: how can organisms be robust against the effects of mutations yet simultaneously adaptable when the environment changes? ...> Full Article


Evolution caught in the act (1/3/2010)

Mutations are the raw material of evolution. Scientists at the Max Planck Institute for Developmental Biology in Tübingen, Germany, and Indiana University in Bloomington have now been able to measure for the first time directly the speed with which new mutations occur in plants. Their findings shed new light on a fundamental evolutionary process. They explain, for example, why resistance to herbicides can appear within just a few years. ...> Full Article

Time in a bottle: Scientists watch evolution unfoldA 21-year Michigan State University experiment that distills the essence of evolution in laboratory flasks not only demonstrates natural selection at work, but could lead to biotechnology and medical research advances, researchers said. ...> Full Article


Evolution coup: Study reveals how plants protect their genes (9/11/2009)

Unlike animals and humans, plants can't run and hide when exposed to stressful environmental conditions. So how do plants survive? A new University of Montreal study, published in the journal Proceedings of the National Academy of Sciences, has found a key mechanism that enables plants to keep dangerous gene alterations in check to ensure their continued existence. ...> Full Article


Species diversity helps researchers refine analysis of human gene mutations (9/7/2009)

In the September issue of Genome Research, Dr. Sudhir Kumar led a team of researchers at the Biodesign Institute at Arizona State University in examining DNA mutations from both healthy and diseased patients.Their work evaluates the reliability of computer models aimed at predicting the eventual effect of such mutations. ...> Full Article



We are all mutants (8/30/2009)

We are all mutantsResearchers have calculated a general rate of one mutation in each 15 to 30 million DNA letters in humans. Using next-generation sequencing, researchers sequenced part of the Y chromosome from two distant male-line relatives. Despite 13 generations of separation -- with a common male ancestor 200 years ago -- they found only four letters that differed. Mutation is the ultimate source of human genetic variation and has implications for both evolutionary and disease genetics. ...> Full Article

Tiny differences in our genes help shed light on the big picture of human history (5/2/2009)

Scientists from Cornell University have developed a new tool for identifying big events in human history and pinpointing the origins of specific gene mutations. This research, published in the May issue of the journal GENETICS, helps shed light on times when the human population moved close to extinction and helps scientists close in on gene mutations that make some demographic groups more likely to develop diseases such as cancer, heart disease, diabetes, among others. ...> Full Article


Researchers show adaptation plays a significant role in human evolution (1/19/2009)

For years researchers have puzzled over whether adaptation plays a major role in human evolution or whether most changes are due to neutral, random selection of genes and traits. "Others have looked for the signal of widespread adaptation and couldn't find it. Now we've used a lot more data and did a lot of work cleaning it up," said Dmitri Petrov, associate professor of biology at Stanford University and a senior author of the paper. ...> Full Article
