...xuality. Verhey asked the 103 enrolled students to classify their beliefs about evolution and creationism before and after the course. Most of the 66 students who completed the survey had previously been exposed to both evolutionary and creationist accounts of life. Sixty-one percent of students in the interv...New book expands biological classifications to account for 'alien' life
...a type of life goes extinct doesn't mean you don't classify it. Otherwise you wouldn't have dinosaurs on the tree of life. And until now there hasn't been any place to put RNA life." In the current popular classification system the highest levels are three domains bacteria, archaea and eukarya, the last of ...First big influenza genome study reveals flu evolution
...ra) cause widespread flu among humans. Researchers classify type A influenzas according to structural variations in two surface proteins: hemagglutinin (HA) and neuraminidase (NA). Like changing coats, the influenza virus changes the shape of these HA or NA proteins when it accumulates minor mutations or reas...Finding rewrites the evolutionary history of the origin of potatoes
... job is to help determine what is a species and to classify those species into related groups," Spooner explains. "Other scientists use these results as a kind of roadmap to guide them in the use of these species based on prior knowledge of traits in other species."
