When various organisms and plants first began conducting photosynthesis, the process did not result in the production of oxygen (anoxygenic photosynthesis). However, in time, a switch occurred, which enabled the emergence of an oxygenic (oxygen-production) version of the process. A team of experts now analyzes how th... |
