why is it impossible for animals to grow to certain sizes without collapsing under their own weight? If you just scale everything up 1:1, why can’t they just function normally at increased sizes?
In: Biology
Animals need to be adapted for their size. Larger animals need very complex mechanisms for getting oxygen to their tissues in comparison to insects for example. Also as size increases, surface area:volume ratio decreases, so less heat is lost. Animals will therefore evolve an optimal size for temperature regulation in their environment.
