  1. Agriculture in beetles
    Think of weevils and most likely you'll think of spoiled food. But some weevils have turned to farming...

  2. Secondary xylem (wood) in vascular plants
    Evolution of wood in plants as distantly related as lignophytes, Calamites and Lepidodendron is an elegant example of convergent evolution. Plants responded in a similar way to a need for better structural support as they diversified and increased in size.

  3. Torus-margo pits in vascular plant xylem
    Torus-margo pits probably evolved once in the gymnosperms, after the split of more advanced gymnosperms from the cycads. Surprisingly, eight genera from five families of angiosperms, which are characterised by highly effective xylem vessels, have also evolved torus-margo structures.

  4. Autumn leaf colouration
    Autumn colours are likely to be adaptive, as the 'default' is simply to remain green up to leaf fall, and both red and yellow leaf colouration have evolved independently on many occasions in gymnosperms and woody angiosperms.
