An important requirement of life is a means of minimally accurate self-replication. Biologist Jack Szostak explains that “In order for RNA to have emerged as the genetic polymer that enabled protocells to evolve in a Darwinian manner, the process of RNA replication must have been accurate enough to allow for the transmission of useful information from generation to generation, indefinitely.”

Though there is no direct evidence for Adam and Eve having existed, this does not necessarily make the belief irrational. In principle, it may be supported by indirect evidence (if one holds to a religious belief, itself well supported by evidence, that implies the historicity of Adam and Eve). Either way, current science tells us little about whether Adam and Eve plausibly existed.
The intricacies of vertebrate blood clotting represent a significant challenge to evolutionary mechanisms. The process of clot formation is itself irreducibly complex and must also emerge simultaneously with a mechanism to prevent excessive clotting and to confine the clot to the site of injury. From a neo-Darwinian perspective, it is difficult to envision such a system emerging one step at a time without passing through maladaptive intermediate stages.
