Supporters of evolution generally respond by arguing that this objection is simply an argument by lack of imagination, or argument from incredulity: a certain explanation is seen as being counterintuitive, and therefore an alternate, more intuitive explanation is appealed to instead. In actuality, evolution is not based on "chance", but on predictable chemical interactions: natural processes, rather than supernatural beings, are the "designer". Although the process involves some random elements, it is the non-random selection of survival-enhancing genes that drives the evolution of complex and ordered patterns. The fact that the results are ordered and seem "designed" is no more evidence for a supernatural intelligence than the appearance of complex non-living phenomena (e.g. snowflakes). It is also argued that there is insufficient evidence to make statements about the plausibility or implausibility of abiogenesis, that certain structures demonstrate poor design, and that the implausibility of life evolving exactly as it did is no more evidence for an intelligence than the implausibility of a deck of cards being shuffled and dealt in a certain random order.
It has also been noted that arguments against some form of life arising "by chance" are really objections to nontheistic abiogenesis, not to evolution. Indeed, arguments against "evolution" are based on the misconception that abiogenesis is a component of, or necessary precursor to, evolution. Similar objections sometimes conflate the Big Bang with evolution.
Christian apologist and philosopher Alvin Plantinga, who believes evolution must have been guided if it occurred, has formalized and revised the improbability argument as the evolutionary argument against naturalism, which asserts that it is irrational to reject a supernatural, intelligent creator because the apparent probability of certain faculties evolving is so low. Specifically, Plantinga claims that evolution cannot account for the rise of reliable reasoning faculties. Plantinga argues that whereas a God would be expected to create beings with reliable reasoning faculties, evolution would be just as likely to lead to unreliable ones, meaning that if evolution is true, it is irrational to trust whatever reasoning one relies on to conclude that it is true. This novel epistemological argument has been criticized similarly to other probabilistic design arguments. It has also been argued that rationality, if conducive to survival, is more likely to be selected for than irrationality, making the natural development of reliable cognitive faculties more likely than unreliable ones.
A related argument against evolution is that most mutations are harmful. However, the vast majority of mutations are neutral, and the minority of mutations which are beneficial or harmful are often situational; a mutation that is harmful in one environment may be helpful in another.

=== Unexplained aspects of the natural world ===

In addition to complex structures and systems, among the phenomena that critics variously claim evolution cannot explain are consciousness, hominid intelligence, instincts, emotions, metamorphosis, photosynthesis, homosexuality, music, language, religion, morality, and altruism (see altruism in animals). Most of these, such as hominid intelligence, instinct, emotion, photosynthesis, language, and altruism, have been well-explained by evolution, while others remain mysterious, or only have preliminary explanations. No alternative explanation has been able to adequately explain the biological origin of these phenomena either.
Creationists argue against evolution on the grounds that it cannot explain certain non-evolutionary processes, such as abiogenesis, the Big Bang, or the meaning of life. In such instances, evolution is being redefined to refer to the entire history of the universe, and it is argued that if one aspect of the universe is seemingly inexplicable, the entire body of scientific theories must be baseless. At this point, objections leave the arena of evolutionary biology and become general scientific or philosophical disputes.
Astronomers Fred Hoyle and Chandra Wickramasinghe have argued in favor of cosmic ancestry, and against abiogenesis and evolution.

== Impossibility ==
This class of objections is more radical than the above, claiming that a major aspect of evolution is not merely unscientific or implausible, but rather impossible, because it contradicts some other law of nature or is constrained in such a way that it cannot produce the biological diversity of the world.

=== Creation of complex structures ===

Living things have fantastically intricate features—at the anatomical, cellular and molecular level— that could not function if they were any less complex or sophisticated. The only prudent conclusion is that they are the products of intelligent design, not evolution.
Modern evolutionary theory posits that all biological systems must have evolved incrementally, through a combination of natural selection and genetic drift. Both Darwin and his early detractors recognized the potential problems that could arise for his theory of natural selection if the lineage of organs and other biological features could not be accounted for by gradual, step-by-step changes over successive generations; if all the intermediary stages between an initial organ and the organ it will become are not all improvements upon the original, it will be impossible for the later organ to develop by the process of natural selection alone. Complex organs such as the eye had been presented by William Paley as exemplifying the need for design by God, and anticipating early criticisms that the evolution of the eye and other complex organs seemed impossible, Darwin noted that:

[R]eason tells me, that if numerous gradations from a perfect and complex eye to one very imperfect and simple, each grade being useful to its possessor, can be shown to exist; if further, the eye does vary ever so slightly, and the variations be inherited, which is certainly the case; and if any variation or modification in the organ be ever useful to an animal under changing conditions of life, then the difficulty of believing that a perfect and complex eye could be formed by natural selection, though insuperable by our imagination, can hardly be considered real.
Similarly, ethologist and evolutionary biologist Richard Dawkins said on the topic of the evolution of the feather in an interview for the television program The Atheism Tapes:
