And that while this sexual ‘three-or-moresome’ has some pretty great advantages, it also forces plants to spend a fair amount of energy just in attracting the middle men.… Read more

When autumn comes, leaf shedding deciduous species effectively shut it all down. They reabsorb as many nutrients as they can from their leaves, throw the remaining orange-red husks to the ground, and hunker down for the cold times.… Read more

With time, the proteobacteria evolved into the modern mitochondria, a process that involved most of its very own bacterial genome being stolen away, and sequestered in the nucleus of the host.… Read more
