Algae Knew about Quantum Mechanics 2 bln yrs Before Humans

In a new study, a team of chemists from the University of Toronto in Canada have observed quantum mechanics at work in photosynthesis in marine algae, which suggests algae knew about quantum mechanics nearly two billion years before humans.

"Our latest experiments show that normally functioning biological systems have the capacity to use quantum mechanics in order to optimize a process as essential to their survival as photosynthesis," said chemistry professor Greg Scholes, lead author of the study.

Scholes and his colleagues isolated light-harvesting complexes from two different species of marine algae and studied their function under natural temperature conditions using a sophisticated laser experiment known as two-dimensional electronic spectroscopy.
