How come in general evolutionary ancestors of most living species were bigger? Megalodon > sharks Sabre tooth etc > lions, tigers Prehistoric birds > modern birds Mammoths > elephants Ancient crocodiles > modern Moore’s law of evolved design miniaturization?

So you’re getting at sort of a size stability question? Eh why animals don’t hit an optimal/maximum size and then exist at that size indefinitely as long as that kind of animal remains viable?

Something like that. Biology seems to lack a general economies of scale mechanism. It’s usually special case like blue whale.

Seems like non-animals might be an interesting line of exploration here: high CO2 produced gigantic cycads, but I don’t know that I’ve heard of vegetation larger than Sequoias.

I was just thinking perhaps plants scale like backend industrial process tech while animals scale like consumer tech
