Can Random Genetic Mutations provide Natural Selection the Raw Material it Requires to Create New Species?
Darwin Starts with a Populated Environment
Darwin’s theory of Decent with Modification through Natural Selection does not address how life began. Darwin’s theory attempts to explain how, over time, some members of a well marked species may begin to diverge in organic structure, habits, etc. into incipient (or emergent) species and eventually into an entirely new species. Darwin’s studies, observations, and postulations begin with an environment already significantly populated with organisms. For instance, in The Origin of Species chapter on the Struggle for Existence, the struggle is against numerous other competing species and is a central component to Darwin’s theory on Natural Selection.
Darwin states in The Origin of Species, Instinct chapter:
“I must premise, that I have nothing to do with the origin of the primary mental powers, any more than I have with that of life itself (1).”
Darwin’s definition of Natural Selection
Darwin states, in The Origin of Species:
“Can it, then, be thought improbable, seeing that variations useful to man [under domestic breeding] have undoubtedly occurred, that other variations useful in some way to each being in the great and complex battle for life, should sometimes occur in the course of thousands of generations? If such do occur, can we doubt that individuals having any advantage, however slight, over others, would have the best chance for surviving and of procreating their kind? On the other hand, we may feel sure that any variation in the least degree injurious would be rigidly destroyed. This preservation of favorable variations and the rejection of injurious variations, I call Natural Selection.” (1)
I must briefly comment on The History Channel’s recently aired two hour program titled “How Life Began.” I watched it, curious to find out what the latest thinking is regarding this subject. The show should have been titled “How DID Life Begin?” Throughout the program, we were taken through a Life Factory that can create living cells. In one segment, the “goop” destined to become a living cell, disappeared behind a curtain and the narrator said something like, “We don’t really know what happens behind that curtain, but somehow a living cell emerges.” The rest of the program (most of it) was a case study in Evolution. The program was full of speculative explanations for how life began and has “evolved” into the diversity we see today in the world around us. It made the case that everything has been figured out except for a few nagging details and none of the many difficulties with the Neo-Darwinian Theory of Evolution were discussed. In summary, there’s nothing new here. Click HERE for a more thorough review of the program.
Now, for the good stuff. I’ve been doing a lot of research on DNA, gene theory, etc. and find the topic fascinating. The complexity of DNA, coding and manufacturing mechanisms is astoundingly complex.
Big Science teaches that all living things are the product of time and chance as proposed by Neo-Darwinism or current evolutionary theory. It is taught in public schools as fact when it is at BEST a weak theory based on many unproven assumptions. However, as science marches forward, this theory is developing cracks and is beginning to crumble under the weight of serious scrutiny. Here I will document a few thought provoking “challenges” evolution faces.
As I look around at nature, I see a huge amount of variety among both the plant and animal kingdom. You can almost sense a statistically uniform distribution of characteristics, attributes, etc. from least complex to most complex. For example, one could argue the difference in physical complexity between a chimpanzee and a human is not that great. Both have similarly complex DNA, organs, etc. However, there is at least one anomaly that can be observed – the gap in intelligence between humans and the next most intelligent life form. If one could measure and then graph the intelligence of all life forms, the graph might look like the following:
