Is Darwin's theory of evolution correct?

Darwin's theory of evolution by natural selection with some variations been broadly accepted by the science community over the past century. Evolutionary biologist Richard Dawkins famously commented: "If you meet somebody who claims not to believe in evolution, that person is ignorant, stupid or insane." Biologist Stephen Meyers disagrees. He answers this question well in this short video by raising two significant doubts that force one to be skeptical about this theory. The first is the Cambrian explosion, where many species appeared without antecedents in multiple biological  big bangs and secondly, the DNA enigma, where extremely remote random mutations give rise to meaningful DNA sequences. The animated video summarises Meyer's book-length treatments of those two problems.  https://m.youtube.com/watch?v=DOIbcOoaxuY&feature=youtu.be   The Cambrian Explosion. A weird and wonderful thing happened 530 million years ago: A whole bunch of major groups of animals appeared abruptly within a geologically short window of time about ten million years. These novel animal forms emerged in the fossil record without evidence of earlier ancestors. So where did they come from? This question really bothered Darwin. And he acknowledged that he could give it "no satisfactory answer." Nor can scientists today.  Biologist Eugene Koonin, of the National Center for Biotechnology Information, describes the abrupt appearance of the Cambrian animals and other organisms such as dinosaurs, birds, flowering plants and mammals as a pattern of "biological Big Bangs."  So what caused all these new forms of life to arise?  In the 1950s, James Watson and Francis Crick made a startling discovery: The DNA molecule stores information as a four-character digital code. Strings of precisely sequenced chemicals inside the DNA helix store the instructions—the information—for building the crucial proteins that cells need to survive. Unless the chemical "letters" in the DNA text are sequenced properly, a protein molecule will not form. No proteins; no cells. No cells; no living organisms.  Bill Gates has said, "DNA is like a software program." Let's think about that for a second. For computers to run faster and perform more functions, they require new code. Well, the same is true for life: To build new forms of life, the evolutionary process would need to produce new genetic information—new code. But this raises questions about the creative power of natural selection and mutation. Natural selection is a simple sorting process. Species keep favorable mutations that allow them to survive but eliminate bad mutations that cause their members to die out. No one doubts that natural selection is a real process and that it produces minor variations, but many biologists now doubt that it produces major innovations in biological form.  To see why, think again about software. What happens if you introduce a few random changes into computer code? You'll likely mess it up, right? Though it might still work—if you don't make too many changes. But if you make enough random changes, your program will stop functioning altogether. You certainly can't keep doing this and expect some cool, new program to pop out. There's a mathematical reason for this. In all codes and languages, there are vastly more ways of arranging characters that will generate gibberish than there are arrangements that will generate meaningful sequences.   And this applies to DNA.   Remember, natural selection only "selects" sequences that random mutations generate. Yet experiments have established that DNA sequences capable of making stable proteins are extremely rare—and, thus, really hard to stumble on randomly.   How rare? While working at Cambridge University, molecular biologist Douglas Axe showed that, for every DNA sequence that generates a relatively short functional protein, there are 10 to the 77th power nonfunctional sequences. Now consider that there are only 10 to the 65th power atoms in our galaxy. So finding a new DNA sequence capable of building a functional protein is like searching blindfolded for a single marked atom among a trillion Milky Way galaxies. Talk about a needle in a haystack!  In his book Darwin's Doubt, even 4 billion years of life's history is not enough time to overcome a search problem this big.  So, two serious doubts about modern Darwinian theory: The Cambrian Explosion—the sudden appearance of new animals, which evolutionary theory has failed to explain; and the DNA enigma—the implausibility of random mutations producing the information needed to build new forms of animal life. Scientists who know about these problems are not "ignorant, stupid, or insane;" they are just appropriately skeptical.
