Same-Handed Molecules Are an “Overarching Design Principle” in Life, Say Researchers
Without foresight to solve heterochiral incidents, a primordial cell would quickly perish even if, against all odds, it began homochiral.
Why Epigenetics Contradicts Evolutionary Theory
Epigenetic mechanisms are ubiquitous in biology. Because of epigenetics, organisms with otherwise identical genes (e.g., twins) can be quite different.
For Navigating Animals, a Gift from Magnetotactic Bacteria
Nowhere do these scientists explain how bacteria invented magnetotaxis and encoded it into their genes.
Engineers Crash the Evolution Party, Rethink Biological Variation
Miller and Luskin discuss fruit flies, finch beaks, stickleback fish, mutational hotspots, phenotypic plasticity, and the gravity well model.
Studies on Insect Wings Validate Engineering Models for Adaptation
The “long-winged” phenotype is generated if the environmental conditions deteriorate due to reduced food supply or overpopulation.
