How Did Life Get Started?

The next section of I Don’t Have Enough Faith to Be an Atheist deals with the design of life. It focuses particularly on the most difficult problem of all for Darwinists – where did the first life come from?

The authors point out that the first problem when talking about evolution is in its definition. Darwinists make no distinction between microevolution and macroevolution, and thus use the evidence for micro to prove macro. Microevolution has been observed (changes within species), but it can’t be used as evidence for macroevolution, which has never been observed (the evolving of one organism into another kind of organism). Natural selection, the device Darwinists say that powers evolution, has never been observed to create new types.

There are five reasons the authors list to explain why natural selection can’t create new life. For one thing, there seems to be genetic limits built into basic types of animals. For example, dog breeders create different kinds of dogs, but the dogs always remain dogs. Secondly, the change that occurs within types of animals appears to be cyclical rather than directed toward the development of new life forms. The two authors use an example of Darwin’s finches, which were noted as having varying beak sizes depending on the weather. No new life forms came into existence; only the beak sizes changed in these birds. The third reason involves something called irreducible complexity. Living things are filled with molecular machines that are irreducibly complex, meaning that all the parts of each machine have to be completely formed and in the right places and in the right size in the correct operating order at the same time for the machine to function. The authors use as an example a car engine, which needs so many systems to operate together for success. These complex biological systems could not have developed in a gradual Darwinian fashion because intermediate forms would be nonfunctional. All the right parts must be in place in the right size at the same time for there to be any function at all. A fourth problem with natural selection is the non-viability of transitional forms. The authors use as an example the Darwinian assertion that birds evolved gradually from reptiles. Such a change would necessitate a transition from scales to feathers, but how could a creature survive that no longer has scales but does not quite have feathers? A creature with the structure of half a feather has no ability to fly. Finally, the authors discuss molecular isolation. If all species share a common ancestor, the authors indicate we should expect to find proteins sequences that are transitional from fish to amphibian, for example. That’s not what is found. Scientists have discovered that the basic types are molecularly isolated from one another, which seems to preclude any type of ancestral relationship.

But Darwinists say the fossil record supports their position – does it? It actually lines of better with supernatural creation. There aren’t missing links – there’s a missing chain. Nearly all the major groups of animals known to exist appear in the fossil record abruptly and fully formed in strata from the Cambrian time period. This is been called the Cambrian explosion or biology’s Big Bang. This, of course, is completely inconsistent with Darwinism. There’s no evidence of gradual evolution but of instantaneous creation instead.

Again, I’m going to quit at this point even though I have not finished the chapter in the book. There’s plenty here to think about.
