Leaf size and venation show remarkable diversity across dicotyledons, and are key determinants of plant adaptation in ecosystems past and present. Here we present global scaling relationships of ...

Galapagos daisies evolved similar jagged leaves through different genes. This shows evolution can reach the same result in ...

A doctoral student has identified a long-overlooked pattern in how plants evolved their equivalent of lungs -- tiny pores on the surfaces of leaves called stomata. Using specialized imaging techniques ...

Pick up a leaf and it is hard not to notice the pattern made by the veins. For years, biologists, mathematicians and even poets and philosophers have tried to decipher the rules and regulations behind ...

“Leaves have evolved over millions of years to optimize light collection, transport of nutrients to and from the plant body, and mechanical stability against natural stresses,” says David Young a ...
