The “selectivity filters” in membrane channels of living cells are able to discriminate between very similar molecules or atoms using complex mechanisms.
It wasn’t until Jorn Dyerberg encountered ID researchers like Michael Behe that he gave it that name.
Winston Ewert recently published a paper in BIO-Complexity suggesting that life is better explained by a dependency graph than by a phylogenetic tree.
From the molecular nanomachines within a tiny cell to the large-scale structure of the universe, design is everywhere to be found.
