0 Darwin Awards<br />
Darwin Awards “The Darwin Awards” is a Web site<br />
and series <strong>of</strong> books started in 1993 by Wendy Northcutt, a<br />
molecular biology graduate at the University <strong>of</strong> California<br />
in Berkeley. She began collecting stories <strong>of</strong> human stupidity,<br />
then opened a Web site in which people from all over<br />
the world can submit similar stories. Although the books<br />
and Web site claim to <strong>of</strong>fer examples <strong>of</strong> human evolution<br />
in action, it is highly unlikely that any <strong>of</strong> the stories actually<br />
represent the process <strong>of</strong> natural selection. They are,<br />
however, an interesting and entertaining way to examine the<br />
difference between the popular and scientific conceptions <strong>of</strong><br />
natural selection.<br />
The people in the Darwin Awards stories commit outlandish<br />
acts <strong>of</strong> stupidity that either kill them or prevent them<br />
from reproducing. Either way, their genes will not be represented<br />
in the next generation. They have removed themselves<br />
from the human gene pool in what the author calls “a spectacularly<br />
stupid manner,” which will contribute to the eventual<br />
evolutionary improvement <strong>of</strong> the entire species. This is<br />
the fundamental premise <strong>of</strong> the Darwin Awards.<br />
Examples include: A woman burned herself to death<br />
because she was smoking a cigarette while dousing anthills<br />
with gasoline; a man took <strong>of</strong>fense at a rattlesnake sticking its<br />
tongue out at him, and when he stuck his tongue out at the<br />
snake, the snake bit it; a college student jumped down what<br />
he thought was a library laundry chute, but libraries do not<br />
have laundry chutes, and the chute led to a trash compactor;<br />
a man electrocuted himself trying to electroshock worms out<br />
<strong>of</strong> the ground for fish bait; and a man tried to stop a car that<br />
was rolling down a hill by stepping in front <strong>of</strong> it. These are<br />
all stories that Northcutt attempted to verify before publishing<br />
them, and they are probably true.<br />
Despite the tremendous value <strong>of</strong> these stories as entertainment,<br />
it is unlikely that they actually represent evolution<br />
in action. The principal reason for this is that the death <strong>of</strong><br />
these individuals does not necessarily represent the removal<br />
<strong>of</strong> what could be called judgment impairment genes from the<br />
population. The lack <strong>of</strong> intelligence demonstrated by some <strong>of</strong><br />
these people may not arise from any consistent genetic differences<br />
between them and the rest <strong>of</strong> humankind. Even in<br />
cases where a specific genetic basis for intelligence has been<br />
sought, it has not been found; in the Darwin Awards database,<br />
it has not been sought. If the stupidity <strong>of</strong> the people<br />
arose from habits <strong>of</strong> thought they acquired from upbringing<br />
and society, then their deaths will have contributed nothing<br />
to natural selection.<br />
These stories may not represent a lack <strong>of</strong> intelligence so<br />
much as excessive impulsiveness. The proper order for intelligent<br />
action is (1) think, (2) act; to reverse these two steps<br />
is not necessarily as stupid as it is impulsive. The question<br />
then becomes, are there conditions in which impulsiveness<br />
confers a possible evolutionary benefit? He who hesitates<br />
long enough to think will sometimes live longer, but he<br />
will also sometimes miss an opportunity to acquire status,<br />
resources, or reproductive opportunities. Modern humans<br />
are sometimes intelligent, sometimes impulsive, and modern<br />
humans have inherited both <strong>of</strong> these behavioral patterns<br />
from prehistoric ancestors (see intelligence, evolution<br />
<strong>of</strong>; sociobiology).<br />
Most scientists believe that human genetic evolution has<br />
not recently progressed in any particular direction (although<br />
random genetic changes have continued to occur). Rather<br />
than allowing natural selection to eliminate inferior versions<br />
<strong>of</strong> genes, humans have invented technological responses to<br />
everything from the need for more food, to responding to<br />
the weather, to the control <strong>of</strong> diseases. Most scientists who<br />
study human evolution will insist that no measurable increase<br />
in brain size has occurred in the last 100,000 years, and no<br />
increase in brain quality in about 50,000 years.<br />

Darwin, Charles (1809–1882) British <strong>Evolution</strong>ary scientist<br />
Charles Darwin (see figure on page 109) was the<br />
scientist whose perseverance and wisdom changed the way<br />
pr<strong>of</strong>essional scientists, amateurs, and almost everyone else<br />
viewed the world. He presented a convincing case that all<br />
life-forms had evolved from a common ancestor, and for<br />
a mechanism, natural selection, by which evolution<br />
occurs. Earlier scholars had proposed evolutionary theories<br />
(see Buffon, Georges; Chambers, Robert; Darwin,<br />
Erasmus; Lamarckism), but, until Charles Darwin, no proposals<br />
<strong>of</strong> evolution were credible.<br />
Charles Robert Darwin was born February 12, 1809, in<br />
Shrewsbury, England, the same day that Abraham Lincoln<br />
was born in the state <strong>of</strong> Kentucky. Both men, in different<br />
ways, led the human mind to consider new possibilities and<br />
freedoms without which future progress would not have been<br />
possible. Darwin, like many other aristocratic Englishmen,<br />
was born into a rich and inbred family. His father, Robert<br />
Darwin, was a prominent physician, and his mother, Susannah<br />
Wedgwood Darwin, was an heir <strong>of</strong> the Wedgwood pottery<br />
fortune. Robert Darwin and Susannah Wedgwood were,<br />
in addition, cousins. Unlike other rich inbred Englishmen,<br />
Charles Darwin was to put his inherited wealth to better use<br />
than perhaps anyone ever has.<br />
Darwin had three older sisters, an older brother, and a<br />
younger sister. Scholars do not know what kind <strong>of</strong> impact<br />
the death <strong>of</strong> Darwin’s mother had upon him. Her death was<br />
painful and prolonged, and Darwin was only eight years old.<br />
Whether this event might have inclined him to think more <strong>of</strong><br />
evolutionary contingency, rather than divine benevolence, as<br />
the ruling order <strong>of</strong> the world, scholars can only speculate.<br />
The Darwin family was respectably but not passionately<br />
religious. Robert Darwin was secretly a freethinker<br />
but remained associated with the Anglican Church. Susan-
