In allometric growth, by contrast, different parts grow at different rates.
Different breeds of dog achieve their different shapes by means of genes that change the allometric growth relationships between the parts of the body.
Correlation does not give you the directionality of causation, so a few types of answers have been proposed — one is "junk" (large cells better tolerate the selective cost of useless DNA), one is "skeletal" (read Cavalier-Smith, it's complicated and involves a hypothesized allometric relationship), etc.
Not that maximal rigor is needed to establish your basic point here, but nowadays such allometric comparisons are typically done by regressing the variable that you are interested in (brain size) on the confounding variable (body size) and then examining the residuals instead of looking purely at proportions.
In fact, their eyes were somehat larger than would be expected from allometric dropoff in eye size in tetrapods.
How in the world can someone understand a paper describing the allometric law relating metabolic rate to body mass unless they understand power law relations, exponential and logarithmic functions, and linear regression?
Professor D'Arcy Wentworth Thompson, last of the great Victorian polymaths, author inter alia of the classic allometric study On
In all cases the PMO was well tolerated at doses equivalent to 80 mg/kg and 110 mg/kg in humans respectively (based on standard allometric scaling), suggesting the potential for a wide therapeutic index.
Model Quantum metabolism is an analytic theory of metabolic regulation which exploits the methodology of quantum mechanics to derive allometric rules relating cellular metabolic rate and cell size.
