'Fossil genes' reveal how life sheds form and function
...umans came to depend more on sight as color vision displaced a sense of smell that, in the distant past, was far superior to what humans enjoy today. In the Japanese yeast, the seven fossil genes that make up the eroding pathway are "still in the same place (on the genome) they are in neighboring species," say...Genetic clues found for common congenital brain disorder

...c relationships can be disrupted if one partner is displaced by an invader. Plants that rely on ants to disperse seeds generally produce a tough-coated seed that has a little ant snack, called an elaiosome, attached to it. A foraging ant picks up the seed and drags it off, often to an ant nest. The food reward...Invasive species: A few bucks and a click away
