Studies of co-evolution biased toward “striking and exaggerated phenotypes”, researchers say

The authors seem to suspect that “the widespread impression that coevolution is a rare and quirky sideshow to the day-to-day grind of ecology and evolution” is wrong and that new tools for uncovering it will show it to be more common. Co-evolution must require a fair amount of cooperation between utterly different life forms. If natural selection is the model, one failure would end a multi-stage process. Read More ›

“We suspect that if one’s model system or species of study does something unique and interesting, TRGs [taxonomically restricted genes, aka orphans] will be at least partially responsible, and worth seeking out.” Curiously, the PNAS paper seems to show that. Read More ›

From ScienceDaily: A new study in the Proceedings of the National Academy of Sciences breaks down the genetic history of 1,700 species of ants and 10,000 plant genera, and the researchers found that the long history of ant and plant co-evolution started with ants foraging on plants and plants later responding by evolving ant-friendly traits. … “There are a number of different structures plants make that are specific for ant use,” explains Nelsen, who led the study with his fellow Field Museum researchers and co-authors Rick Ree and Corrie Moreau. “Some plants have evolved features that persuade ants into defending them from attack from other insects and even mammals. These include hollow thorns that ants will live inside, or extra Read More ›
