Genetic Study Tackles Slow Plant Domestication Mystery

By Diana Lutz, Washington University in St. Louis Domestication genes tend to be insensitive to the rest of the genome and to the environment. Could finding this subset of robust genes have slowed things down? “The Modern View of...

Genetic evidence supports role of gene family in cancer development Researchers have found a major piece of genetic evidence that confirms the role of a group of virus-fighting genes in cancer development. Our understanding of the biological processes that cause cancer is limited. UV light and smoking are two well-understood cancer-causing processes. Exposure to either of these processes causes distinguishable patterns of genetic damage, or 'signatures', on the genome that can lead to...

From time to time, living cells will accidentally make an extra copy of a gene during the normal replication process. Throughout the history of life, evolution has molded some of these seemingly superfluous genes into a source of genetic novelty, adaptation and diversity. A new study shows one way that some duplicate genes could have long-ago escaped elimination from the genome, leading to the genetic innovation seen in modern life. Researchers have shown that a process called DNA...

redOrbit Staff & Wire Reports - Your Universe Online A newly-identified genetic association with facial asymmetry in ancient cavefish could shed new light into mysteries surrounding conditions such as cleft palate or hemifacial microsomia in humans, according to research appearing in a recent edition of the peer-reviewed journal Genetics. Joshua Gross, an assistant professor in the University of Cincinnati’s Department of Biological Sciences, and his colleagues compared the...

Humans Drive Evolution Of Conch Size
2014-03-19 15:47:45

Smithsonian Tropical Research Institute The first humans to pluck a Caribbean fighting conch from the shallow lagoons of Panama's Bocas del Toro were in for a good meal. Smithsonian scientists found that 7,000 years ago, this common marine shellfish contained 66 percent more meat than its descendants do today. Because of persistent harvesting of the largest conchs, it became advantageous for the animal to mature at a smaller size, resulting in evolutionary change. Human-driven evolution...

Europeans' Appearance Altered Over Five Millennia Of Natural Selection

April Flowers for redOrbit.com - Your Universe Online A great deal of research has been focused on the factors that have influenced the human genome since the end of the last Ice Age. An international team of scientists—including anthropologists at Johannes Gutenberg University Mainz (JGU), geneticists at University College London (UCL), and archaeologists from Berlin and Kiev—has analyzed ancient DNA from skeletons, finding that natural selection has had a major effect on the human...

Unraveling The Hidden Variation Of Bacteria
2014-03-07 13:02:27

Instituto Gulbenkian de Ciencia This news release is available in Portuguese. Our intestines harbor an astronomical number of bacteria, around 100 times the number of cells in our body, known as the gut microbiota. These bacteria belong to thousands of species that co-exist, interact with each other and are key to our health. While it is clear that species imbalances may result in disease, it is unclear at what pace does each species in the gut evolves, a process that contributes to the...

It's Not All Sexual Selection
2014-03-05 14:54:45

University of Maryland Baltimore County Since the days of Darwin, scientists have considered bird song to be an exclusively male trait, resulting from sexual selection. Now a team of researchers from the University of Maryland, Baltimore County (UMBC), the University of Melbourne in Australia, Leiden University in the Netherlands and The Australian National University says that's not the whole story. The team used information from several sources, including the Handbook of the Birds of...

Researchers Discover Gene Responsible For Dissected Leaves
2014-02-14 13:19:31

Max Planck Institute Arabidopsis thaliana lost the RCO gene over the course of evolution and thus forms simple leaves Spinach looks nothing like parsley, and basil bears no resemblance to thyme. Each plant has a typical leaf shape that can differ even within the same family. The information about what shape leaves will be is stored in the DNA. According to researchers at the Max Planck Institute for Plant Breeding Research in Cologne, the hairy bittercress (Cardamine hirsuta) has a...

Paleontology
2014-01-12 00:00:00

Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...
