The Present
Oxygenic photosynthesis accounts for virtually all of the production of organic matter from non-organic ingredients. Production is split about evenly between land and marine plants, and phytoplankton are the dominant marine producers.
The processes that have driven evolution are still operating. Well-known examples include the changes in coloration of the peppered moth over the last 200 years and the more recent appearance of pathogens that are resistant to antibiotics. There is even evidence that humans are still evolving, and possibly at an accelerating rate over the last 40,000 years.

Famous quotes containing the word present:
“Talk to them about things they don’t know. Try to give them an inferiority complex. If the actress is beautiful, screw her. If she isn’t, present her with a valuable painting she will not understand. If they insist on being boring, kick their asses or twist their noses. And that’s about all there is to it.”
—John Huston (1906–1987)
“How do you know antiquity was foolish? How do you know the present is wise? Who made it foolish? Who made it wise?”
—François Rabelais (1494–1553)
