> Why don’t more plants evolve towards the “grass” strategy?
Grasses have a trick: Grass blades grow at the base of the blade and not from elongated stem tips. This low growth point evolved in response to grazing animals and allows grasses to be grazed or mown regularly without severe damage to the plant. https://en.wikipedia.org/wiki/Poaceae#Description
In The vital Question https://en.wikipedia.org/wiki/The_Vital_Question Nick Lane is arguing that the eukaryote symbiotic cell (archea host, bacterial mitochondria symbiot) leads, via sex and the requirement for gene compatibility between the small mitochondrial genome and the host nuclear genome, to a "best fit" pressure on organism with extreme metabolism. Simplified, "Heartbeat hypothesis" (https://en.wikipedia.org/wiki/Rate-of-living_theory) doe snot apply to, say, birds, that have extreme metabolic requirements (= flight). The fact that, among mammals, is bats that fit the same longevity may indicate that the mitochondrial-nucleus gene match idea could be right.

Evolution, because no other phenomenon can drive the required complexity to reach 'life'. Natural selection works by inheritance and mutation. Things that can create copies of themselves with mutations that allow selection to act on, this list is short.
