A Lot of Hand-Waving by Evolutionists

by Lenny Esposito

In college, I was a physics major. In physics, we sought to provide some precise answers to specific data presented to us. For example, we know that a car turning a corner must rely on a certain amount of friction to turn a corner. We want to know how to calculate this so we can set safe speed limits on corners. In chemistry, we seek to know just what is happening when iron rusts or an acid and a base are combined. In medicine we seek to know exactly why someone who suffers from Sickle cell disease. Doctors have traced the problem back to a single DNA point mutation which then changes the coding of a single amino acid.1 This is pure science, seeking to find an answer while examining the details.

Of course, not all science can be done in this way. There are fields such as plate tectonics that take observed data and use them to create models of how the different plates of the earth’s crust will affect each other. Still, these models attempt to be very specific in just what is moving and how, and it’s this specificity that makes the difference in the explanatory value of any theory. The devil’s in the details, as it were.

What’s Needed to Make a Whale

Yet, when I talk with proponents of evolution, the discussions are different. Yesterday, I engaged again in an exchange with a proponent of evolution. I asked his again to provide a definition, to which he replied “Evolution Is Change in the Inherited Traits of a Population through Successive Generations” (borrowing the title from this web site.) But, as I wrote yesterday, that’s not a very useful definition. Just because things change doesn’t mean we get new biological systems. Men can be four feet tall or seven feet tall, but not 12 inches tall or 12 feet tall. Those who inherit the sickle cell trait are immune from malaria, but their children are at risk of a painful life and an early death. Even here, the inherited immunity isn’t a new feature, but a crippling of a functioning system.

So, I ask for specifics. I offered the humpback whale as an example. Supposedly, the whale evolved from a land mammal over the course of about 10-12 million years.2 One may try to explain the size increase by simple growth over time, (although a recent article in the journal Science says that such an explanation fails), there are still a huge amount of systems that must be changed for a land-dwelling mammal to change into an ocean-dwelling one. The nose must be migrated to the top of the head and turned into a blow hole. Breathing is no longer automatic but must take conscious effort. Walking limbs must be transformed into flippers. The kidneys must be changed to handle the intake of salt water. Testes must be located inside the body to keep warm. The young must be able to nurse under water, and on and on…
