Over the last few years, I've received various reactions from the public about my articles on transhumanism. Those reactions have ranged all across the board--from spewing hatred to mocking skepticism to genuine interest.

Now that Ebola is here, it has captured the attention it arguably deserved from us long ago. The latest news is that the patient first diagnosed in the U.S. is in critical condition, and receiving experimental therapy. Lapses in our public health system have been acknowledged, and a scramble to contain the damage, and prevent spread, are playing out as we look on, and worry.

God and Some Scientists

Kelly James Clark

In a recent New York Times op-ed, evolutionary biologist David Barash recounts telling the undergraduates in his animal behavior class that evolutionary science has "demolished two previously potent pillars of religious faith and undermined belief in an omnipotent and omni-benevolent God." Barash's claims of demolition are more "op" than "ed," I'm afraid.

There is much that remains to be learned about the evolutionary process. Many problems remain without known solutions. But the sources of genome variation, including rapid changes throughout the genome, are no longer mysterious.

Why Do Giraffes Have Long Necks?

Clearly the giraffe evolved this uncommon and helpful trait in order to reach those nourishing leaves. That's how natural selection works. If you're a 6-year-old.

Is The Male Desire For Younger Women The Cause Of Menopause?

Vivian Diller, Ph.D. | Posted 11.24.2013 | Fifty
Vivian Diller, Ph.D.

Many women are bewildered by menopause. Even scientists struggle to explain its very existence in human females. You see, women (along with short-finned and killer whales) are among the small handful of species unable to reproduce until the end of life. It wasn't always that way -- menopause evolved over history -- and there are few good hypotheses to explain why.

On the Origin of Cuckolds

Baba Brinkman | Posted 08.17.2013 | Science
Baba Brinkman

Confronted with the hyper-vigilant and often violent jealousy of generations of men protecting their genetic legacy, evolution predicts a psychological arms race between the sexes, producing ever more keen-eyed and suspicious men and ever more creatively deceptive women.

In correspondence and comments on some of my blogs, there have been confusions or questions as to what I mean by "natural genetic engineering" (NGE). I will use this blog to spell out what my understanding of NGE is.

The Power of Sexual Selection: How Psychology Influences Evolution and Vice Versa

Our psychology has been shaped by a sometimes uneasy balance of natural and sexual selection -- the practical need to acquire our daily bread and the romantic need to find love and produce offspring.

We have a natural environment. And a world of fast-food drive-through restaurants, fax machines, escalators and email is not it. The nutritional environment we live in is toxic to us. The effects of that toxicity are rampant chronic disease and epidemic obesity.

Darwin and the Atom

Victor Stenger

In commemoration of Charles Darwin's birthday, we will be reading again about evolution. Much of it will have been said before, many times. Here I am going to try to take a less familiar line and show how Darwinian evolution by natural selection has roots in the atomism of ancient Greece.

Who Was the Greatest Psychologist?

Allen Frances | Posted 04.11.2013 | Science
Allen Frances

In most realms of human endeavor, no one person ever stands out as clearly greater than the other greats in that field. Because so many are great, no one person ever shines brightest. Psychology is an exception -- Charles Darwin does tower over this field.

This particular morning in mid-April was quite chilly, although clear. In fact, the early suffusion of sunlight was promising a day of great beauty. Not that Michelle was listening to such promises. Far too busy. And besides, the climate inside was always perfect.

We have long known that lucky charms and superstitious rituals provide psychological comfort to those hoping to win the lottery, knock in a winning run, or get an A on a calculus exam, but now there is good evidence that our superstitions actually work -- not through magic but through psychology.
