Phylogenetic comparative methods (PCMs) use information on the historical relationships of lineages (phylogenies) to test evolutionary hypotheses.The comparative method has a long history in evolutionary biology; indeed, Charles Darwin used differences and similarities between species as a major source of evidence in The Origin of Species.

For example, an individual plant might receive either more or less water during its growth cycle, or the average temperature the plants are exposed to might vary across a range. A simplification of the norm of reaction might state that seed line A is good for "high water conditions" while a seed line B is good for "low water conditions".
In the light-independent (or "dark") reactions, the enzyme RuBisCO captures CO 2 from the atmosphere and, in a process called the Calvin cycle, uses the newly formed NADPH and releases three-carbon sugars, which are later combined to form sucrose and starch. The overall equation for the light-independent reactions in green plants is [27]: 128
Palm trees form are in unrelated plants: cycads (from the Jurassic period) and older tree ferns. [231] Flower petals came about independently in a number of different plant lineages. [232] Bilateral flowers, with distinct up-down orientation, came about independently in a number of different plants like: violets, orchids and peas. [233] [234]
