New Article in Science Boosts Plausibility of a Primordial Pair

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 Incredible Design of Vertebrate Blood Clotting

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.
