Chevalier de Lamarck

Different organisms originated separately by spontaneous generation from nonliving matter.

We now see a hierarchy of species because they differ in age

Species differ from one another because they have different needs.

The biphasic C4 system reduces photorespiration dramatically by increasing levels of CO2 near Rubisco to enable Rubisco carboxylation to outcompete the oxygenation reaction.

In CAM plants, Nocturnal phosphorylation of PEPCase controls primary carboxylation. PEPCase‐kinase transcripts accumulate during the night, controlled by the circadian oscillator and metabolites.
