In Jean Auel’s blockbuster novel, “The Mammoth Hunters,” the beautiful Ayla muses on the coming hunt. “How could creatures as small and weak as humans challenge the huge, shaggy, tusked beast, and hope to succeed?” she asks herself.

The cluster of white domes on Siding Spring Mountain in New South Wales, Australia, reminded me of the bulbs of the white Aminita mushrooms that spring up overnight in the New England woodlands after an autumn rain.

The world of Gilbert White
Exactly 200 years ago on this date [April 21, 1786], Gilbert White heard the voice of the cuckoo in the woods above Selborne village. Gilbert White was the curate of Selborne, a tiny village nested in a quiet dale about 40 miles southwest of London. The village has changed little since White’s day, and has become a place of pilgrimage for all who love nature.

Evolutionary games on the computer
Those who oppose evolution often claim that the theory is not “scientific.” They say that no hypothesis can qualify as science unless it can be tested by a controlled experiment.

Paradox of Paradoxides
Boston, Charlotte, N.C., St. John’s, Nova Scotia, Wexford, Ireland, and Holyhead, Wales, have something in common. All are situated on rocks that contain the fossils of a certain extinct trilobite, or marine arthropod, that are found nowhere else.

Rights of animals
When I was a boy growing up in Tennessee I once snitched my uncle’s .22 rifle and went hunting with my friends. My first shot brought a gray squirrel tumbling down through the branches of a tree. The squirrel lay on the ground at my feet, its belly pierced by a neat red hole, convulsed with pain. I watched, paralyzed by horror at what I had done, until one of my friends dispatched the squirrel with the butt of his rifle.

Random numbers that aren’t
Thirty years ago, at about the time I began to study science, I came across a book called “A Million Random Digits.” Here, in a volume as thick as the Boston telephone directory, were page after page of numbers with no apparent pattern. No matter how long you studied the numbers, there was no way to predict what digit would occur next.

The real story on Ireland’s snakes
In this space a year ago on Saint Patrick’s Day I wrote a little natural history of the shamrock. In that piece I said there was no evidence to suggest that Saint Patrick ever used the semi-mythical three-petaled plant to illustrate a lesson on the Trinity.

Pacing-off the cosmos
An old proverb says that a journey of a thousand miles begins with a single step. It is literally true that a single step was the beginning of our journey into the universe of the galaxies.

Snow and poker
Who could have predicted this almost snowless winter? Here it is March and I still haven’t taken my snow shovel out of the basement. I checked the “Old Farmers Almanac.” I checked the newspapers. As far as I can discover, no forecaster anticipated the remarkable deficit of snow in my part of the New England.
