That’s Bananas!—How flowers get fancier
Frivolous as it may sound to us, making pretty flowers is serious business for a plant. Fancier flowers often mean more attention from pollinators and greater reproductive success, and the huge diversity of flowers around today shows that the evolution of new flower types has paid off. But how can plants afford to experiment with such an important developmental process? As Becky Povilus explains, they do and they don't.
The evolutionary implications of viral life
We aren't even sure if they are really alive, but, as Maryam Chaib de Mares explains, the distribution of viruses across the three domains of life (Bacteria, Archaea, and Eukarya) may reflect how viruses have shaped the evolution of cellular life.
