Document Summary
Enire evoluion of mulicellularity was enabled by suicient oxygen concentraions. Energy required for making certain products in mulicellular organisms requires certain levels of oxygen. Surface area to volume rule has such high predicive power allometry can predict features of organisms. If oxygen is the key factor in mulicellular organisms, and relaive surface area is changing. Break up coal into dust, or air is full of dust, then lighing a match will blow it up. Explosive surface area is larger in dust than coal. Dust in the middle of coal is blocked from transfer processes. Fundamental morphological and physiological funcions come back down to it. Coal has a small surface area and won"t burn surface area increases with decreasing size of chunks, allowing it to ignite easily. Lump = elephant, dust = insects, insects run at a higher rate. Insects have larger relative surface area than the elephant. Convert to log form exponenials into straight lines.
