The recent discovery of a giant squid with huge basketball size eyes has been promoted as an evolutionary survival response for detecting enemy sperm whales that would eat it.
But, how did the squid avoid the whales while its big eyes were still evolving over, supposedly, millions of years? Partially evolved eyes over millions of years do no good. Natural selection wouldn't have preserved them. The truth is the squid's eyes were designed from the beginning!
Natural selection occurs in nature but it doesn't produce biological traits. It only "selects" them. Natural selection can only "select" from biological traits and variations that are possible and which have survival value. If a variation occurs that helps a species survive, that survival is called being "selected." That's all it is. It's simply another term for survival of the fittest. There's no conscious selection by nature. It's a passive process. Natural selection is a figure of speech. The term itself is a tautology. Natural selection only operates once there is life and reproduction, not before.
Genes, not natural selection, produce biological traits. The real issue is not natural selection but what traits are genetically possible.
There are limits to evolution and natural selection in nature. Only evolution within biological "kinds" is possible (such as varieties of dogs, cats, horses, cows, etc.). Evolution is not possible across biological "kinds." The genes already exist in all species for micro-evolution (evolution within "kinds") but not for macro-evolution (evolution across "kinds").
Genetic information cannot happen by chance. Therefore, genetic and biological similarities between species are better explained due to a common Designer Who designed similar functions for similar purposes in all the various forms of life.
What about "Junk DNA"? The latest science shows that "Junk DNA" isn't junk after all! It's we who were ignorant of how useful these segments of DNA really are. Recent scientific research published in scientific journals such as Nature has revealed that these "non-coding" segments of DNA are vital in regulating gene expression (how, when, and where genes are expressed in the body). Just because these segments don't code for proteins or traits doesn't mean they're not useful or that they don't code for something else.
How did species survive if their vital tissues, organs, reproductive systems, etc. were still evolving? Read my Pravda Internet article: WAR AMONG EVOLUTIONISTS! I discuss: Punctuated Equilibrium, "Junk DNA," genetics, mutations, natural selection, fossils, genetic and biological similarities between species.
