From a biology perspective, it may not be totally advantageous to grow in all three dimensions at once. Certainly, as life forms become larger, they also require more energy to sustain, and also become harder to cool (at least for the warm blooded ones). Generally speaking, keeping cool is a matter of surface area (aka skin). But growing double in each of the three dimensions would be 4x more skin than before, but would be 8x more mass/muscle. That’s now harder to keep cool.

So growing needs to be done with intention: growing taller nets some survival benefits, such as having longer legs to run. Whereas growing wider or deeper doesn’t do very much.

But idk mang, I’m in a food coma from holiday dinner, just shooting from the hip lol
