Why we flock to zoos

Why we flock to zoos

In the NYT, Diane Ackerman asks why human animals flock to zoos.

More than 150 million people a year visit zoos and aquariums in the United States. Why do we flock to them? It’s not just a pleasant outing with family or friends, or to introduce children (whose lives are a cavalcade of animal images) to real animals, though those are still big reasons. I think people are also drawn to a special stripe of innocence they hope to find there.

Crow playing on the rooftop snow

I’m always on the lookout for images of non-human animals using tools. A recent example, including a photo of a gorilla using a stick to test the depth of river water during a crossing. But also consider this crow:

And speaking of amazing animals, consider this finding regarding rats:

The often maligned rodents go out of their way to liberate a trapped friend, a gregarious display that’s driven by empathy, researchers conclude in the Dec. 9 Science.

E. O. Wilson’s Theory of Everything

E. O. Wilson’s Theory of Everything

The November 2011 edition of The Atlantic presents E. O. Wilson’s “Theory of Everything.” Wilson’s theory takes into account the “eusocial” status of human animals, something that we share with ants and bees, but very few other species. Eusocial animals build complex societies wherein “individuals specialize in various activities and sometimes act altruistically.” Wilson has taken the position that eusociality is not the result of close genetic similarity (the explanation offered by “kin selection”). Rather, he is a strong advocate of “group selection.” By the way, E. O. Wilson is no relation to another Wilson who has strongly advocated group selection, David Sloan Wilson (and see here). Here’s how E. O. Wilson presents group selection, according to a passage from The Atlantic:

In his new book, Wilson posits that two rival forces drive human behavior: group selection and what he calls “individual selection”—competition at the level of the individual to pass along one’s genes—with both operating simultaneously. “Group selection,” he said, “brings about virtue, and—this is an oversimplification, but—individual selection, which is competing with it, creates sin. That, in a nutshell, is an explanation of the human condition.

“Our quarrelsomeness, our intense concentration on groups and on rivalries, down to the last junior-soccer-league game, the whole thing falls into place, in my opinion. Theories of kin selection didn’t do the job at all, but now I think we are close to making sense out of what human beings do and why they can’t settle down.”

By settling down, Wilson said, he meant establishing a lasting peace with each other and learning to live in a sustainable balance with the environment. If Wilson’s new paradigm holds up—“and it will,” he insisted in an e-mail exchange several weeks after visiting Gorongosa—its impact on the social sciences could be as great as its importance for biology, advancing human self-understanding in ways typically associated with the great philosophers he criticized.

“Within groups, the selfish are more likely to succeed,” Wilson told me in a telephone conversation. “But in competition between groups, groups of altruists are more likely to succeed. In addition, it is clear that groups of humans proselytize other groups and accept them as allies, and that that tendency is much favored by group selection.” Taking in newcomers and forming alliances had become a fundamental human trait, he added, because “it is a good way to win.”

This article is a wide ranging work that offers much insight into Wilson’s history and accomplishments, and more. For instance, Wilson, an early outspoken advocate of sociobiology, takes some shots at Stephen J. Gould, who he calls a “charlatan.” Several decades ago, it was the now-deceased Gould who led the attack against Wilson regarding sociobiology.

This is an excellent read, and I highly recommend it.

A day at the zoo

Yesterday, my daughter and I visited the Saint Louis Zoo. The idea was to have some fun shooting photos of the animals. The day was overcast and cool and many of the animals were active. I shot each of these photos using a Canon S95 pocket camera.

Gallery of ten photos below (hit “full size image” for correct aspect ratio).

Visiting with gorillas in the wild

This lucky tourist in Uganda had the experience of a lifetime. As he wisely sat motionless, a group of gorillas came of to check him out. The gorillas enter the camp at about the one-minute mark. Here’s the story at Huffpo, and here’s the video:

Huge find of ancient whale fossils in the desert

In a desert in northern Chile, scientists are busy digging out dozens of fossils of the ancestors of modern whales, many of them complete skeletons. The fossils are up to seven million years old. This will add to an impressive collection of whale and pre-whale fossils already in the scientific record. And see here.
