ARE YOU INTELLIGENTLY DESIGNED?

A4I never came away from an autopsy without reflecting on the marvelous design of the human body. I don’t know how many autopsies I attended over the years as a cop and a coroner. Lots. It’s not something you score. But I always looked at postmortems as a scientific—almost spiritual—systematic exercise in examining human design. 

They’re twelve major systems in your anatomy—all interlinked to ensure your survival. Remove any system (except maybe your reproductive one) and you’ll die. And these systems go about their intermingling business—day after day—year after year—without you having to consciously think about operating them.

Think about it.

A11All that’s required to live is a bit of maintenance and, when things go wrong, modern medical science usually knows how to patch you up. Today’s medical practitioners can replace your organs, your limbs, your hair, your eyes, your nose, and your teeth.

But what modern science doesn’t know is how all this came to be.

A5I’m going to do some edited plagiarism from William  A. Dembski, of the Access Research Network, who wrote on intelligent design. The idea has been around since the ancient Greeks, who did some pretty deep thinking about where they came from and where they were going.

Some of it was explained by mythology, some by theology, and some by analogy. But the central question—did something intentionally design us—remains unanswered today.

Personally, I think there’s a force of infinite intelligence at work. A force we’re not capable of truly understanding, comprehending, or explaining.

Design theory—also called design or the design argument—is the view that nature shows tangible signs of having been designed by a preexisting intelligence.

The most famous version of the design argument can be found in the work of theologian William Paley who, in 1802, proposed his “watchmaker” thesis. His reasoning went like this:

A12“In crossing a heath, suppose I pitched my foot against a stone, and were asked how the stone came to be there; I might possibly answer, that, for anything I knew to the contrary, it had lain there forever. … But suppose I had found a watch upon the ground, and it should be inquired how the watch happened to be in that place; I should hardly think the answer which I had before given would be sufficient.” 

To the contrary, the fine coordination of all the watch parts would force us to conclude that it must have had a maker—that there must have existed, at some time, and at some place or other, an artificer or artificers, who formed it for some purpose. We’d struggle to comprehend its construction and designed its use, just as we’ve struggled to understand ourselves.

A13Paley argued we can draw the same conclusion about many anatomical objects, such as the eye. Just as a watch’s parts are all perfectly adapted for the purpose of telling time, the parts of an eye are all perfectly adapted for the purpose of seeing. In each case, Paley argued, we discern the marks of an intelligent designer.

Although Paley’s basic notion was sound and influenced thinkers for decades, Paley never provided a rigorous standard for detecting design in nature. Detecting design depended on such vague standards as being able to discern an object’s “purpose.” Moreover, Paley and other “natural theologians” tried to reason from the facts of nature to the existence of a wise and benevolent God. They tried to prove God from the perception of perfect products.

All of these things made design an easy target for Charles Darwin when he proposed his theory of evolution. 

A16Whereas Paley saw a finely-balanced world attesting to a kind and just God, Darwin pointed to nature’s imperfections and brutishness. Although Darwin had once been an admirer of Paley, Darwin’s own observations and experiences—especially the cruel, lingering death of his 9-year-old daughter Annie in 1850—that destroyed whatever belief he had in a just and moral universe.

Following Darwin’s widely-accepted theory of evolution, the notion of design was all but banished from biology.

A17Since the 1980s, however, advances in biology have convinced a new generation of scholars that Darwin’s theory was inadequate to account for the sheer complexity of living things. These scholars—chemists, biologists, mathematicians, and philosophers of science—began to reconsider design theory. They formulated a new view of design that avoids the pitfalls of previous versions.

Called intelligent design (ID), to distinguish it from earlier versions of design theory (as well as from the naturalistic use of the term design), this new approach is more modest than its predecessors. Rather than trying to infer God’s existence or character from the natural world, it simply claims that “intelligent causes are necessary to explain the complex, information-rich structures of biology and that these causes are empirically detectable.”

Like I said, I never came away from an autopsy without a scientific and spiritual reflection on the marvelous design of the human body.

WHAT’S SO SPECIAL ABOUT THE HUMAN BRAIN?

AA1Why do we study other animals and they don’t study us? What is it about the human brain that allows the cognitive ability for abstract reasoning and creativeness? What is it that makes the human brain so special? It comes down to one thing that humans do that no other living creature does.

I just watched a fascinating TED Talk by neuroscientist Dr. Suzana Herculano-Houzel where she looks at the difference in animal brain structures and arrives at a shocking, yet simple explanation.

AA6For years, mainstream science assumed that there was a direct relationship to the rate of intelligence and the size of the brain. However if you look at the brain of a cow to the brain of a chimp, they both weigh around 400 grams. Using that theory, the two species should have about the same intelligence. Carrying it further, a human brain weighs about 1.5 kilograms, an elephant’s is 4.5 kilos, and a blue whale tops out at 9 kg. Something clearly is wrong with the size of the brain vs. intelligence theory.

Is there an intelligence relationship in the size of an animal’s brain to the size of its body?

Take gorillas for instance. Their bodies average 180 kg and their brains are 0.5 kg. Human bodies average 75 kg and our brains are 1.5 kg. So the human brain to body ratio are 7.2 times larger than gorillas and we appear to be a lot smarter – although that’s debatable with some people.

But the daily energy consumption that a human brain requires is proportionately much higher than a gorilla’s brain.

AA8Gorillas spend most of their day feeding to supply energy in keeping a larger body mass fuelled, whereas humans only require three quick meals to support a smaller body but a larger and more active brain. Human brains are only 2% of our body mass but require 25% of our energy consumption to operate. Gorilla brains only consume 10% of their daily calorie intake. So what’s going on here?

Dr. Herculano-Houzel researched the long-held assumption that there was a direct proportion of neurons, or thought processors, per weight of grey matter. It was thought that the human brain held around 100 billion neurons but she could not find the source of this information. So she decided to do some experimentation.

AA9She developed a process to extract neuron nuclei from grey-matter cells and established that the average human brain contains 86 billion neurons – 16 billion in our cerebral cortex alone, which is by far the highest in any species and the seat of cognitive awareness.

She observed that there was nothing different in the basic structure between human brains and other primates like gorillas, chimps, and orangutans. And yes, humans are just another species of primate. It’s just that we have a much higher brain to body size ratio and we have a lot more neurons that our cousins do.

AA13But our brain to body energy requirements are so much higher than apes, yet we feed far less. This led her to ask the question – What happened in our evolutionary process that made human brains so proportionately larger?

Anthropology determines that the human brain suddenly increased about 1.5 million years ago. Something else happened at the same time.

Humans learned to cook their food.

AA12We learned to use fire to pre-digest our caloric intake which supercharged the ability to fuel and grow the brain. Because of cooking high-calorie, high-protein foods, our brain size rapidly increased to becoming a large energy-consuming asset rather than a liability.

Humans spent far less time searching for, devouring, and digesting low calorie raw vegetative foods than other primates did. Our omnivorous diet allowed us to focus our cerebral cortex on developing better food processing ventures like agriculture, civilization, electricity, and supermarkets.

So what do we do that no other creature does?

We cook.
