The elk now steer clear of areas where they perceive risk from wolves, leading to the regrowth of aspens, willows, cottonwood trees, and berry-producing shrubs. That in turn has supported the resurgence of beaver and bird populations.

# Despite cartoons you may have seen showing a straight line of fish emerging on land to become primates and then humans, evolution is not so linear. The brains of other animals are not merely previous stages that led directly to human intelligence.
# Instead—as is the case with many traits—complex brains and sophisticated cognition have arisen multiple times in independent lineages of animals during the earth’s evolutionary history.
# With this new understanding comes a new appreciation for intelligence in its many forms. So-called lower animals, such as fish, reptiles and birds, display a startling array of cognitive capabilities. Goldfish, for instance, have shown they can negotiate watery mazes similar to the way rats do in intelligence tests in the lab.

In preparation for Charles Darwin's upcoming 200th birthday, the editors of Nature compiled a selection of especially elegant and enlightening examples of evolution.

They describe it as a resource "for those wishing to spread awareness of evidence for evolution by natural selection." Given the continuing battles over evolution in America's public schools — and, for that matter, the Islamic world — such a resource is most welcome.

However, I'd like to suggest another way of looking at the findings below, which range from the moray eel's remarkable second jaw to the unexpected plumage of dinosaurs. They are, quite simply, wondrous — glimpses through an evolutionary frame of life's incredible narrative, expanding to fill every possible nook and cranny of Earth's biosphere.

Why are environmentalists shooting goats? Why have they undertaken an elaborate plan to systematically kill hundreds of thousands of goats by means of aerial and ground hunting operations? Why to preserve life, of course.

To navigate the currents of ecological fate, most creatures adapt — but a few have stuck to their evolutionary guns.

Known as living fossils, they lasted for millions of years with barely a change, even as their relatives went extinct or took different paths across the tree of life.

Many are now threatened or endangered. But with some luck and a little help, living fossils will be able to survive the age of humans, too.
