ANN ARBOR — A new paper from scientists in North America, Europe and China reveals important details about key transitions in the evolution of plant life on our planet.

From strange and exotic algae, mosses, ferns, trees and flowers growing deep in steamy rain forests to the grains and vegetables we eat and the ornamental plants adorning our homes, all plant life on Earth shares more than a billion years of history. (more…)

*Research genetically traces flowers to a single common ancestor*

From southern Africa’s pineapple lily to Western Australia’s swamp bottlebrush, flowering plants are everywhere. Also called angiosperms, they make up 90 percent of all land-based, plant life.

New research published this week in the Proceedings of the National Academy of Sciences provides new insights into their genetic origin, an evolutionary innovation that quickly gave rise to many diverse flowering plants more than 130 million years ago. Moreover, a flower with genetic programming similar to a water lily may have started it all. (more…)

BERKELEY, Calif. — Studying the environment would be simple if it weren’t for one thing: Even an isolated ecosystem is unbelievably complicated. Factors to study include water systems, plant life cycles, carbon dioxide fluctuations, resource use by humans, and far more — and each can be studied at the scale of a plant or of the planet, and measured in an instant or over decades.
