Despite what creationists will tell you, proteins DO self-assemble into complex structures through Brownian motion. Brownian motion is the random movement of molecules driven by thermal energy. This process is extremely well-studied and understood, with decades of research in biophysics, structural biology, and molecular evolution confirming its fundamental role in life. Despite the seemingly chaotic nature of molecular motion, proteins fold and assemble into highly specific functional complexes with remarkable reliability. The key lies in thermodynamics and molecular complementarity—interactions like hydrogen bonding, hydrophobic effects, and electrostatic attractions guide subunits into their correct configurations. From enzyme complexes to ribosomes, and even massive molecular machines like ATP synthase, self-assembly through Brownian motion is not just a theoretical idea—it is an experimentally verified, mathematically modeled, and routinely observed cornerstone of molecular biology.
